I bought a fj1100 last week.
I have 2 GP1200 waverunners a 1997 and a 1999 now I have a 85 fj1100 too.
So far its a nice bike the transmision will need undercut gears probably when it gets colder and I put her away for winter.
Low miles on the clock 18000 ml needs a rear tire and I need to get licenced.
Then its taking a 8 hour trip to Tennesse
My waverunners have been modified my 99 is waiting on LA Sleeve to resleeve one of my cylinders to fix a stuck piston I had earlier this year.
Its on Max bore has raised comp and is ported.It should be pushing around 165-170 HP.
Who knows whats in store for my j1100 in the future :good2:
welcome to the group scotty!
the kookaloo is strong in you! :good2:

I will learn my way aroud the bike and the website.
Hope im not in the wrong place but how do you post pics.
Welcome to the group..
Thanks for the welcome guys.I might buy a Dunlop GT501 150/80-16 for the rear.
I have a Maxxis 120/80-16 v rated on the front and I cant find a v rated Maxxis for the back.I see some nice Radial tires out there for the back but they dont match the front.I did find a Maxxis the right size but it was H rated not V rated.

Thanks for posting pics for me.They are all yamaha's.
I like how the 85 fj100 matches the colors on the 97 GP1200
You're going to have to get a late model FJ1200 to match the other waverunner!
No $$$ left right now.Hurting the 99 GP1200 just cost me $1000 for parts and machining.Then I bought the fj1100.Also my daughter is having a baby boy, today most likely.I am taking a 8 hour road trip on the fj to go see her within the next week.I will be geting my licence tommorow night dmv is open till 7:00pm.
I went and got my permit today but had no way to get my bike there without risking a ticket,tommorow weather permiting 60% chance of rain I have someone who can ride up there with me on his bike.
I also ordered a rear tire Dunlop GT501 150/80B-16 (71V) my Maxxis rear is somewhat worn in the middle im not sure if they will let me test with it or not,if not i will borrow my friends bike.
I had a Texas licence class M 27 years ago lol I expect the test will be no problem :drinks:
As far as a second fj give me some time its far easier to work on one bike if you have a second one to ride whille you work on the first one.
That or I may just start building a second motor.Got lots to learn but I have built lots of 2 stroke Yamaha motors.Leaving things stock performance wise to me is just wrong.Looking stock I like but I always want more power.
I wont be offering advise to anyone because I know verry little I will mostly be watching and listening but I like my 1985 fj1100 a lot and looking forward to riding it and learning more about it.
Daughter is in the hospital im waiting on a phone call from her insignificant other lol.
I did not get my licence they would not let me test because of rain.I did go out there I rode at least an hour in the rain.Bike ran great other than if it sits in the rain.It will have a hard time starting and will run rough for a whille.(not firing on all four)
Im bummed I did not get my licence I might have to wait for Saturday.I need a licensed rider to go with me.
Im off the rest of the week but need a licensed rider to go with me.Schaumburg DMV is just down the street,any takers :lol: :lol:
Schaumburg... Illinois? :unknown:

I was mostly kidding about the late model FJ...the red & white's match, a late model blue would be fairlly close to the other one.
It is much easier to ride one while wrenching on the other. -- and you're not so likely to take shortcuts in order to get back on the road instead of doing things right.

I would like a later model fj with it painted the same color as the 99 GP1200.
She ran great in the rain but had some issues whear she did not like to iddle at the lights.I was thinking it might be ignition related but it could be water dripingon the carbs etc.

I'm in Joliet. I'd be more than happy to accompany you to the DMV, but I'm out of town
this weekend; I'll be back next week. I used to live in Schaumburg (Village in the Park,
just northwest of the corner of Golf and Roselle) and I used to work in Wheeling, so I
know the area pretty well.
If you need anything, let me know. I've got workspace, a fairly extensive set of tools,
and a few spare parts. There aren't many FJs in the area...I've seen a few, but
apparently they aren't members here.

I would like to meet you and thanks for the offer to help out.
that sounds good.I should be fine with the dmv I will find one open on Saturday and go then unless I can find someone who could go during the day this week or tonight as some are open till 7 tonight.
I plan on at least going through my carbs after I go on this trip to see my daughter I have pod filters on there and don't know what jets etc are in there.
If it was my waverunner I would know the carbs on the bike I will figure it out as I go.
But back to the FJ would love to have you give me pointers.
I am waiting on a rear tire in the mail i found a place that will change it for me but I don't have a center stand so I need to figure that out too.
FJ seems like it needs some carb work to me.If it was my GP1200 I would try adjusting the low speed adjuster screws 3 44 mm Mikuni SBN carbs.
FJ has Mikunis but they look quite different.
Cant wait to get my licence and go see my daughter and the new baby its going to be an adventure.I did get a helmet yesterday for the trip.
Bike was not running on all 4 cylinders today after riding in the rain yesterday.I found a few things wrong.Dd not know I could turn the fuel off under the tank and did not know that I could disconect the throttle cable in the middle.My cable was binding causing my rpm to go up if I turn the bars tight.I rerouted it and will test it tomorrow.I found one of the tips inside one of the plug wires caps was stuck on the plug not in the cap.I also found that I need to get some NGK's the Champions in there were no Champions.I fixed the cap stuck the plugs back in made sure all the caps were tight put evrything back together andI did get it to run but not worth a crap.Pulled it apart again and found that the Fuel line had colapsed at the petcock.Clamped the old line and cut it so I could drain the tank and lift it away from the bike thats when I found out that reserve on the petcock is really off lol.Fuel line had been kinked and also had colapsed.I had a new piece of hoe so i put it in and hooked up the tank and put the gas back in.I also found out that I only have one cable on the throttle instead of two.I think I found the right routing for the throttle cable I need new plugs some clamps and a cable and I think she will run as good as she was a few days ago.i will be working on it early,I hope to have her running good so I can rent a motorcycle tailer to take her to the DMV for my test.
The '85 petcock has 2 positions: ON and PRIME.
ON only flows fuel when there is a vacuum present on the diaphragm, or if the shutoff o-ring is missing/bad.
PRIME flows fuel all the time.
There is no Reserve.
DavidR.
what position should the petcock be in then up or down.
Vertical should be ON, horizontal should be PRIME
Do you have the vacuum line connected?
DavidR.
i figured out that down was on and horizontal was primer i still dont know how the primer works its not what im used too.Been trying to get her running all day spent a few hours finding plugs.Cant get her to fire mutch at all and I know my fuel line is good no kinks.
How do work the primer other than just turning it on ?
I could use a phone call with some advice fuel is stoping at the carbs not geting to the cylinders.
630 202 6472 if anyone wants to help.
Vacuum line is on.

All you need to do is turn the petcock to "prime".
The "prime" position just bypasses the vacuum-operated diaphragm which controls the fuel flow in the "on" position. In other words, in the "prime" position fuel should flow freely through the petcock even in the absence of engine vacuum (like, not running). In the "on" position, engine vacuum opens the diaphragm and allows fuel to flow when the engine is running, but blocks fuel flow when the engine is off.
Start with the simple stuff. Pull the hose from the tank connection and see if you've got fuel flowing when it's at "prime". If no, suspect the petcock. If yes, reconnect the hose at the tank, disconnect it at the carb end, and again check for fuel flow.
Don't tear into the carbs until you verify that the fuel is actually getting there...
Rossi
Still wont run.Pulled carbs because I couldnt get One of the drain screws out.
I think the battery might be suspect although it looks new.Was in the garage till 1:00 am.
I opened up the float bowl side and all was good inside I could see the N/S were not stuck closed,pulled acouple of jets out and nothing was clogged.
Reasembled evrything and tried to start her.She would fire ocasionally but only with the throtle closed all the way.
Going to try and work it out later today.
Ohmed out the spark plug caps I dont have a service manual yet so I dont know what they should ohmed out at.It looks like 2 of them are bad though.I lost one of the springs and the small long piece from one of them. :dash2:Going to look for some new caps tomorrow.
Good news shes running bad news I dont have time to get out to Elgin to take the test.
I am running 93 octane I read somewhere that she needs 91 or better is that right.
When i bought it i was told it only needed 87 octane.
What octane do I run in the fj ?

Spark plug cap resistance; 7.5k-12.5k. How were you able to get it running?
I have new ones in stock if needed as well.

Randy, I have a question for ya?? I have always wondered why the oem spark plug ends had resistance built into them? I have replaced the coils and wires on a few bikes and the replacement ignition wiring just had rubber boots on the end of the wires.. I have never ohmed out any of the wires but they dont look as they have any resistance in them?? Just wondering thanks in advance....

Well it has to due with radio frequency interference (RFI). My dad said back in the early fifties laws were passed to reduce the RFI coming from cars. He remembers being able to here a car approaching and leaving the area of his house by the whine in the TV from the ignition system. I googled RFI and it basically says the same thing.
One thing the FJ has is solid core wires which means the resistance must be done within the spark plug boot. When one changes over to the Dyna, Accel or similar system they install carbon core wires which provide the required resistance.
That is my 2 cents...someone else with better electrical expertise can probably can provide more information than I can.
Randy - RPM
I went to the nearest motorsport place I could find and they had some new end caps for the coil wires so I bought two of them.They were slightly diferent in that the tail section was longer but the screw was shorter.I will go back and get two more to match the two I bought.I ran her for at least 75 miles today she ran good but seems to be running rich to me.(no mph #s so far)Alan my friend who went riding with me on his 750 vulcan said he could smell gas when he was riding behind me.I need to address the throtle cable next she wants to rev up if I turn the bars to the right I did try re routing the one cable I have without success.I suspect if I had the second cable it might not want to do that so much.I will put it back to where it was originally I can see wear marks on the frame so It will go back there.That and I have my new GT501 that needs to get mounted on the rear.I missed getting to the dmv today by about 1/2 hour because I had to wait for the shop to open at 10:00 am so Monday its going on a trailer and im driving it to the dmv to take my test.
Do I need to run 91 octane or better im guessing yes so I am running 93.I will buy a manual in a few weeks when im not so broke thats usually the first tool I buy :yes:

Thank you we have 87 89 and 93 at most pumps so I will run 93.I could mix 89 and 93 and get 91 if I wanted though.

Scott,
Slightly off-topic, but there's a couple of rides this week that you and your buddy may be interested in since it sounds like the FJ is back in running condition.
Thursday night, the Chicagoland Dual Sport Riders meet for dinner. Location is a bit up in the air, but right now it looks like Hooters in Downers Grove or Fuddruckers in Schaumburg. 7:00 PM, maybe followed by a short ride. Nice guys. http://www.meetup.com/Chicagoland-Dual-Sport-Motorcycle-Club/ (http://www.meetup.com/Chicagoland-Dual-Sport-Motorcycle-Club/)
Sunday – Chicago Area Riders. Meet at Egg Harbor in Barrington, 210 S. Cook St. (south of County Line Road on Cook), 9:AM – earlier if you want breakfast. Loose affiliation of area riders; not really a club; very diverse but mostly cruisers. Women, men, Harley, sportbikes, even a dual-sport once in a while. They ride pretty slow and stop a lot, but they're good people, and there's usually a nice turnout. No website, but here's the e-mail I received:
"Ladies and Gentlemen.
It is with great pride to announce that the long awaited June ride composed by the very illustrious Ed has been planned for our pleasure and enjoyment.
Tell your friends, your co-workers, your relatives, your clergyman, your congressman, your pets----Facebook--Twitter--You Tube--Craig's list—MSNBC--ebay----to anyone who will listen...........
All are welcomed
No fees------no dues------just YBOYB*

A JUNE SUMMER FUN RIDE
June 27 2010 --- Sunday
(Karen's B-day too!!)
Northerly westerly direction----easy going roads---scenic sights---leisurely paced
Meet at Egg Harbor
Near Route 59 and Lake Cook Road/East Main Street in Barrington
Arrive before 9am if you want to eat, greet, chit, chat, engine bored and stroked, front forks removed and replaced, inner tubes washed, reupholster seat, swing arm bearing greased, learn techniques on how to use your rear view mirror, learn how to insert your ignition key into the switch, etc. etc.
Rolling starts very shortly after 9am
Planned lunch stop in sunny Wisconsin approximately 1ish/2ish pm
Please rsvp Ed at: edbodnar2000@hotmail.com
(* means your butt on your bike lol lol lol)"

Sounds good but I hope to go out of town to see my daughter and her new baby this week so some time after that.Last night the bike wouldnt start the neutral light came on but no headlight and it would not crank.After playing with the sidestand switch all was good.Started this morning as well.
I find my throttle hand goes numb when riding at higher speeds I would like to have some really good paded grips and some decent gloves to soak up the vibrations.What would everyone sugest.Longer grips or extentions to make the bars longer would be good too I think.Also I am going to get new mirrors when i can afford some.There are a lot of little things I will be doing over time to make the fj better for now I just need that licence and im going to rack up some miles :good:

Regular unleaded is fine.... the manual says to use 91RON or greater, in the US we grade fuel using (ron+mon)/2, RON is typically a higher #. I run 87 year round, in Tucson.... 103F today. No problems, she never pings....

A few years ago, I worked on a Late Model stock car team...... the 1st couple times out, we had a major problem with the ignition crapping out on top end. It turned out to be the crappy
carbon-core plug wires...... we put on a set of spiral-wound solid core wires and never had a problem with it again......
The Yamaha engineers chose to use good-quality steel-core wires with a resistive terminator in the cap. Same RFI-suppression, but no worry of the carbon-core crap breaking down at high RPMs.... and the Late Model was only turning ~7500-8000 RPM. The FJ will go to 10Grand....

Im back 1175 miles round trip.

I had a great trip I got lost on the way and had to wing it so I spent extra time in the seat.Next day she got rained on and wouldnt run.I had no spark at that time.Found water in the connectors by the coils checked some other contacts and she fired back up.My Daughter and her new baby boy were doing awesome so I stayed for 2 days then came home.Took 8 hours coming back and took 12 hours going :crazy:
Hot and humid and I pushed her hard so I was having some trouble with the bike when I would slow down to ask directions.Gas was vaporising in the carbs because I am missing the heat shield between the carbs and cylinders.I can safely say she will run the claimed top speed on the spec sheet and a little more though.Somewhere on the return trip one of my rear signals mysteriously dissapeared I thought I had blown a bulb and was going to change it when I saw the turn signal was gone.My 1985 FJ1100 needs a lot of little things done I do have a few parts coming including the heat shield and some rear signals but she is sound enough to get me where I need to go.I also cleaned out the choke cable it was almost jammed so starting is easier and I installed a side stand switch.I had a pod filter come apart and taped it temporarilly so I have bought some new ones I am guessing they get oiled if so what oil and how do you aply it spray/dip ?.I ride my 85 every day it helps with stress,not so yesterday and today.I have never seen so many cops with people pulled over.I went for short rides and came back home.I will be replacing all the turn signals for led ones sometime soon but for now its going to be oem lights.

They emailed me back and I do run them dry.
It looks like rain Sunday and my ported top end for the 99 GP1200 has not come back yet so Sunday I should be able to get the heat shield on the 85 FJ.
I might buy some oil and do a oil change too.
Bike has never run the way I want so I took a look in the carbs last night.Removing the screws was a bitch some had been stripped already.I found that the needles are not stock they have slots and shims.I think there was 6 slots and the clip was in the second one from the top.there was 2 washers one small and one bigger on top of the clip.Where do I set the needle hieght to clean up the low end.Right now she starts hard.If she does not start on the first few tries she drains the battery real quick and then I need a jump.Seems to start a bit easier with a jump.I do have a 2 new batteries lol.......

Scott,
It all depends on whether your bike is rich or lean. The needle position won't make a lot of difference for starting anyhow. This is determined much more by your idle jets, and float height.
Have you thoroughly cleaned the carbs, including all the passages?
David Raforth (SlowOldGuy) sells a kit with every screw for the carbs replaced with socket head SS screws and a set of float jet O-rings and complete instructions on cleaning and base setting of your carbs. Well worth getting a kit (its cheap too) from him.
Alternatively Randy (rpm@swaybar.com) can ultrasonically clean your carbs. I don't know what he charges for this, but others have been very happy.
If you just want to do it all yourself and ask us questions along the way you'll still need to have everything clean and also provide all the sizes of the jets and needles that are in your carbs. While the stock US carb needles only had a single groove, the bikes sold outside the US had 5. And DynoJet (and maybe Factory) needles also had a number of grooves. Do you know (or suspect) that your bike may have had a carb kit installed sometime in the last 25years?

I suspect I am rich because if I add fuel using the choke symptoms get worse.If I blip the throttle it comes back to the same rpm but seems to come down slower than it should.It also sounds fat to me.
The person I bought it off was clueless and didnt know what was done to the bike he had about 15 psi tire pressure and only ran it around his neighbourhood.He didnt even title it.
I sent a email about the carb bolt kit too David Raforth but have not got a reply.I do have a couple of stainless steel cap screws I can use to replace the ones that were already striped.
I need to know what jets I should be running and what slot I should have the clips in :scratch_one-s_head: I also need some pics of a home made carb sinc manometer so I can make one and can see how you hook it up.I have 4 pulse lines and the meter would have 4 vacum tubes but I am using 2 of the vacume lines off of the carb intake tubes.
I did see some residual build up on the needles which I removed.I want to try lowering or raising the needle today I just have not decided wht way to go.
Do I keep the 2 washers above the needle with the small spring or does the small washer fit above or bellow the needle ?

for some reason it seems aftermarket needles tend to put extra wear on the emulsion tubes which in turn will make it run real fat.
its worth giving them a close inspection for ovaling
KOokaloo!

I lowered the needles today and she ran better I also turned in the idle mixture screws (2 turns out) and synced the carbs by looking through the butterflys.
I found a pin hole in one of the Diaphragm's so will need to address that.
Ran her for about an hour with no issues
I lost one of the c clips for a jet needle and the guys at Arlington Motorsports gave me one no charge they have done me good on a few small items for good prices.Got my rear tire mounted there :good: They are just a few minuits away as well they get a recomendation from me.
Carbs have a Dynojet kit in them so I am going to try there setings with and without the stock/dyno pilot air jet.
I have reset the needles and the idle mix screws are 3.5 turns out.Working on starting issue and proper running issue ay the same time I dont think there related but could be.
here is a link to the fj1200 dynojet instructions.

In the kits I have installed on several bikes I have found that DJ tends to go a bit too rich on the main. Try 2 sizes down from the recommendation as a good starting point.
I went with http://www.dynojet.com/pdf/4109.pdf (http://www.dynojet.com/pdf/4109.pdf) for the 85 FJ1100,they even have the 84 and 85 set up diferent I thought they would be the same.
Went out in 6:00 pm traffic and she seems to run good.I wonder what cold starts will be like and what mpg I will get.So far she seems good.
Looked at the trans gears I bought a few weeks ago,I counted the teeth on the gears to see if they were 1100 or 1200 gears.I also counted the teeth on my rear sprocket to see if I had stock gearing.17/40 sprockets and undercut 1100 gears.

Correct that 17/42 sprockets :dance:
Clean em off good, and you'll find the tooth count stamped on them someplace, I'll betcha :)

You are correct #s are stamped on there.I might go with the 18/38 chain and sprocket combo when I get my undercut gears installed.Bike has not needed a jump since Sunday so possibly she is tuned close enough to start without draining the battery so my starting issues would be fixed too.I will need to do the clutch she will slip when the grip gets twisted hard.Forks are super soft they need work.I got shift forks and a drum with the gears what else will I need to have when I do the trans gear swap.I saw the 2nd gear fix write up and I know I will need a couple off tools I was wondering if there was something else I was missing.
Today I built my 99 GP1200 motor and installed it as well.Should be about 165 hp.I need a Illinois sticker and some gas and she is ready for break in.The 97 needs a sticker too.I got a package UPS today 2 windshields for the bike :good: I will put one on the bike in the a.m. I ran out of time after droping the motor in the waverunner.I installed a wall socket a light switch and a series of lamps in the bathroom as well.

Over achiever...... :ireful:
Waverunner fired up and sounds bad ass.Had a garage full of 100 octane exhaust fumes to sniff lol...
She is a nasty girl I will get a sticker for her and then I will go abuse her.
I have a bunch of carb parts coming for the FJ1100 including some carb slides and diaphragms.I lowered my needles 1/2 a slot or 1 washer and she runs better but the pinhole in the diaphragm has her still rough at low rpm mostly at idle.
Scott, maybe let it run in the garage for a good long while with your troublesome neighbor there to keep an eye on things. Make sure you close the door so nobody else is bothered by the noise. Enough carbon monoxide in the blood and he might become a motorhead like you!
My 99 is one of the fastest 97-99 GP1200 in the country as far as I know.Once I get her broke in i will be looking for a RXP 215 hp or a RXPX 255 hp to race.
It should be close I think I can win if I can get a good holeshot.Power to weight ratio should be about the same.My ski wants to get airborne out of the hole its hard to hook up.I wish my FJ1100 would lift the front end like my GP1200 does.
Scott,
For relief of front wheel pressure try this-

just make sure you have a sticky rear tire, my 16" bias plys would just spin!
I took some pics the other day I posted them in the gallery.
I need to go to the river and break in my race motor for my 1999 GP1200 the 97 and 99 go into storage in October.
If you want to see some video there is some youtube video of the 99 before I put the ported cylinders on her.

Hand held GPS jumped out of my pocket about a week ago and got destroyed.
I have put 6000 miles on the FJ1100 and Friday I parked her and have redone the trans and am ready to reinstall the engine as soon as i get the clutch basket bolted back on etc.I will take some pics of the trans damage and post them in the gallery when i am done.
