Sitting around the campfire drinking beer with my brothers. No wait we were fishing. Right. Browsing Kijiji I saw an 84 Fj1100 for $400. Must be crap. Oh well. Couple more beers. Text the guy I will take it.

Turns out it was stored in a heated garage for 20 years. 25,000 kilometers. Since I just finished restoring an 86 a few months ago I decided to tear this one down and get started.

Everything was intact, but two exhaust studs. Hmm. Maybe that's why it was parked. The guy even gave me two chin spoilers for it that were not in the picture. A friend who worked close to the PO picked it up for me. I hadn't even seen it.

So now the fun part. My plan is to do a full restomodification to it. Powdercoat all the steel bits that I am re-using. Clean and paint the motor.

Swap out the swing arm for an FZ1 if I can find one. My current daily driver has an FZ1 set up and I love it.

I also wish to do a complete front end swap. Also while it is apart I am thinking of having the front subframe under the fairing welded up to allow a mirror installation on the fairing, as opposed to the stock handle bar set up.

The old girl is stripped right down to the motor. I will detail it and probably paint it as well. Two exhaust studs where broken. I broke two easy out bits from Crappy tire trying to remove the studs. I ended up carefully drilling out the old studs and tapping new threads. It is impossible ( almost ) to drill a stud out as the bit will want to find the softer metal . Funny how it will do that. Reminds me of horizontal earth boring. The rockets we used 20 years ago would go off in search of the softest soil. Sometimes with disastrous results. ( pulling services out of water mains springs to mind. Pun intended. )
Where was I? oh yes. Drilling out the old broken studs. I didn't get the holes perfectly straight as the bits would walk a little. With care and patience I managed to tap them out and the new studs went in beautifully. Also the exhaust lines back up nicely as well.
I am looking for a donor bike now. A 91-95 FZR 1000 or a YZF600R. Also am thinking still about welding up some brackets to the fairing stay to add mirrors to the fairing. Anyone done this and have any info to share? Does and don'ts?
Johnnie, are you going to pull the head for a peek inside? Possible heat damage?
I wonder what caused those exhaust studs to break.

Pat, everyone likes an excuse to delve a bit deeper but that's drawing a bit of a long bow isn't it? Heat damage? The exhaust is already a 1000 F + at that point on a normal running engine.
Noel
Could excess heat cause exhaust studs to break? I don't know Noel, that's why I put it out there.
1400* egt is common with the turbo Miata crowd...lean conditions put out 1600+ before failure.
One stud breaking, ok just bad luck there...but 2 breaking? It appears that johnnie's '84 is using the oem exhaust system so it can't be from any undue weight on the studs...
Any thoughts on what could break 2 studs on a seemingly stock engine? Over torquing the nuts?
I don't recall johnnie posting any compression or leakdown numbers on the engine.
It would be a shame to come as far as paint, reassembly and startup only to find out that you need engine work...
Great Pat, now I am worried. Honestly based on the condition of the bike I just assumed someone had let it sit for so long that they rusted and broke from trying to remove them. The PO was going to make it into a streetfighter, but couldn't get it running right. He sawed the back fender first , with what looks like the teeth of a beaver. I swapped the original carbs for a clean set of 86 carbs and it ran like a top. The motor is on the bench and we are using it for the valve adjustment tutorial. Perhaps we will uncover valve issues then.

The most common mistake of DIYer's is over tightening. You can always tell when something has been assembled by inexperienced hands wanting to make sure it doesn't come loose, that, butchered screws and hammer bruises. While it
could be many things, the most likely is simply being over tightened by the PO, and in the absence of other indications, not suspicious.
Broken exhaust studs are hardly an uncommon event and rarely, if ever, an indication of something more sinister.
Pat, we seem to have an interruption to regular programming here, your usual common sense and good judgement has abandoned you momentarily. Making a connection between a couple of broken exhaust studs and serious internal problems is indeed a tenuous one and now you've gone and got him all worried. There is no such thing as dismantling a motor just for a "peek", you remove the lid from a jar to have a peek. In the absence of indications suggesting work is required why would pull apart an engine that has been well stored and only has 25,000km's on it? The additional work of removing the head insitu,
if you need to, pales compared to removing it just for a peek.
If it runs well, leave it. If it doesn't fix it.
Motors are never the same once they've been apart.
Noel
Ok, I missed the part about the carb swap, and you got the engine "running like a top..". Carry on
As far as Noel's concerns about r/r the head....and that your motor "will never be the same" is silly.
Broken studs are very common on the FJ/XJ/XJR's in areas that are not dry like the western US.
I sold well over 100 Yamaha exhaust studs (http://www.rpmracingca.com/proddetail.asp?prod=Head%3AExhaustStud) last year.

Thanks Noel. And Randy. When removing the exhaust from my spare motor 4 or 5 studs came right out of the head. I tried removing the nuts from these studs by clamping them in a vice. No way. I could not remove them. Tells me these things can be stubborn. Also we live in the " rust belt ". They salt the roads from Dec. til Mar. The front tire picks the crap up and sprays it onto the front of the motor. Right in the middle. Of course I don't ride on the winter but some years we can actually ride at least one day every month. NOT this year unfortunately.
My comment about worrying was mostly tongue in cheek. This will be my FJ number seven. First one I bought in 87. I have never had the pleasure of any motor problems. So the thought of motor issues didn't occur to me.
Having read so many posts from other re-building projects I almost want to do one!!
Also I appreciate any feed back. Good bad or indifferent.

No problem, the distinction was not lost (and the statement wasn't silly, ask Randy)
Noel
I had several exhaust studs come out when I removed my exhaust, and the ticket for removing the nuts from a loose stud is to double-nut the free end, and then vise it by the tightened double-nuts and remove the stuck nut.
I then stuck all my rusty studs and nuts into my derust-er and then reinstalled them with lock-tight. Unless they're deeply rust pitted, they should be like new.
Update. Found a very nice YZF 600 R front end a week ago. Donor bike is a 97. Bought the complete rear at the same time, caliper, rotor swing arm etc. Getting stoked now to get going on it. Then I looked at the front fender and the blue matches the stripe on my 90. Hmmmmmm. Uh oh. Plans have changed.....
If you're doing the YZZF600 front, get all the RaceTech goodies. Compression & rebound valves and springs too. Don't try it yourself. Get RaceTech, or Traxxion or "The Fan" to do the installation. You'll make a mess of it, guaranteed (DAMHIKIJK I can provide pictures if you still don't believe me).
Thanks Simi-ed. I have been in contact with thefan and he has already given me all the part numbers I need. After watching a video on youtube about how to rebuild one of these I decided to get professional help. It looks like it will cost a few bucks but oh well.
Also can anyone tell me what size tire they use on a YZF front? The tire on it currently is a 110. Could/should I use a 120? Or is the speedo calibrated for the 110.
Wheel is 17 x 3.5. I use a 120/70x17. I don't think there is an appreciable difference in tire height/circumference. I have not checked speedo or odometer calibration. Maybe I should, but it hasn't driven me to go there yet.

Sorry Joe we did the tutorial at the Tech day which we had a few weeks ago. Too bad you couldn't make it!

Well the restomodification has come to a halt as riding season is in full swing here in southern Ontario. Here is what I have been doing. My slave cylinder started leaking and it was rebuilt last year so I ordered a new one from RPM. Also I purchased the crash bars from Herr Randy as well. As usual the parts came quickly and as is normal were the correct ones that fit! Also I ordered a set of CBR mirrors. They are just over 100 a pair new from Honda. One FJ mirror retails for 90 here. Time to take a road trip to Boston.
So here is the update on the Restomodification. After having dismantled the 84 I had some work to do on another bike for a friend. His Buell 1125R needed a valve lash check. That was a pain in the caboose but we got her done. After that my 91 FZR 1000 went in the lift, as it had a small oil leak that was very hard to diagnose. After many months of installing and removing the carbs to run the bike and make it leak we discovered that a small plug that filled in a bore hole for an oil feed was leaking. It was TIG welded and now the leak is gone. Finally after having this low mileage FZR for almost 12 years I can ride it. It has 3100 k on it. The first valve adjustment has not been done yet.
So to get to the matter at hand. I am sending the frame for the 84 off to be powder coated and was wondering what thoughts others had for frame colors. I in the meantime bought another 84 with all the mods. RPM shock, RPM fork valves, Vibranators, Shorai battery, Fzr wheel on front. GSX-R wheel with underslung caliper. I can't remember the rest. The 84 which is stripped will be receiving all the mods as it is being re-built. So it will not be a stock bike. So I am thinking of changing the frame color. Any one have any suggestions? I know Joe will say red.

I have always liked the look of Franks black frame and have to make this decision myself shortly.
To me, the front down tubes are ugly in the way they join and not something to draw attention to and don't "tie in" with the black motor (and until recently, black exhausts) so I painted them black and left the rest silver and I am quite happy with that.
(https://farm8.staticflickr.com/7486/15637542064_c4ec47620d_b.jpg)
I think I would also be happy with an all black frame but it is those down tubes that I most dislike in silver.
Thats a helluva steal, congratulations are in order :drinks:
It would appear you've turned one running scooter into three with some elbow grease and a bit of green.
Frank, that's a cherry ride. Looks a bit like mine but shinier :i_am_so_happy:
Black is always polished but since your scooter doesnt need fresh paint I'd suggest a silver or Chromed frame and maybe some fire truck red & silver shoes. Consider replacing the coil springs on all your OEM lines with gold/brass coils.
Best of luck, maybe you mail me one of those chins when i get arount to cosmetics. If they'll swap onto a 92.

Noel,
Although you claim not to have a polish fetish, your bike always ranks up with the most pristine. Do you have white-glove staff?
Jeff
The paint on the tank and plastics are all nice so I am leaning towards black frame and wheels. Although a darker charcoal grey for them all intrigues me as well.

Haha, I wish. One of the reasons it always looks clean is because it's always getting dirty, really dirty, and gets washed after every ride.
The
really big job is the initial detail when you first get it, from that point on, maintaining it is easy.
It's really not
that tidy. I've put 90,000kms on it in 6.5 years and it is starting to show, mostly with stone chips.

C'mon Noel, you know the score, Pics or it didn't happen. :biggrin:
Another update. Sort of. I did a winter bike trip and the poor bike sat. In the meantime I found a complete FZ1 swing arm and complete front end. So I am thinking of using them on this 84 bike. The YZF front is going onto my current bike. My question now is what is involved in making the shock linkages work. I see a few bikes on here with thunder ace rear ends but no 84's.(The thunder ace appears very similar to me, excusive of the length) My current bike (Black Betty) has the FZ1 rear so I am aware of how that will work, just not the shock linkages.
Also I have an RPM shock for the 84 and am wondering if it can be made to work on this bike with the FZ1 swing arm.

Yes Pat ,exactly like that.
Maybe not as shiny ?
What do you need to know?
To convert the pre-dog bone FJ's ('84-'87) over to the dog bone linkage (needed for the TAce swinger) you need the relay arm off the '89-91 FJ. Later FJ's ('92-'93) had the linkage offset to make room for the ABS pump.
Along with the relay arm, you will need a shorter shock used in the late model FJ's
So I won't be able to use my RPM shock off my 84? I do have a spare relay arm.
No, ask FJ Monkey, he just went through this on converting his '86 over to dog bones while trying to retain use his RPM shock. Monkey Mark wanted to go to the dog bones to add some rake to his FJ. It's a known fact the enhancement in handling when the FJ's rear end is raised, putting more weight on the front tire, so it's shame the RPM shock has no provisions for rear height adjustability.
On my TAce conversion, I did temporarily use my '84 Penske shock (which has a threaded shaft adjustment feature) but even with lower shock clevis** threaded all the way in (i.e. shock as short as possible) the shock was still too long...It worked but, because of the longer length, the angle on the relay arm was not optimum...I traded my '84 Penske shock for a '89 Penske shock which has a shorter shock body.
** I forgot to mention that you will need to convert the lower shock mount over from the eye type mount, to the clevis type mount, needed to fit the '89-91 relay arm.
Thanks Pat. I must now determine if I want to use the GSX-R set up with the RPM shock I have, or use the FZ1 setup with a different shock. HMMM. So many possibilities.
I do have a Penske on another bike, with the rear raised slightly. It does handle very nice, if a bit slow. I am switching over to a YZF front on that bike, once my wheel and top triple get back from powder coat. The YZF front is a little shorter and will place some more weight on the front. The main difference I see between using the FZ1 set up is that one can raise the rear. With the GSX-R set up and a factory swing arm,(84) one can only drop the front end for the same effect.
Johnnie,
another option, one that I am doing to my newly acquired 84 is to use ALL FZ1 components. I am using the swingarm, relay arm with stock dogbones and a shock all off of a 2005 FZ1. you will have to lose the centerstand but for me, my bike didn't have one....no biggie. the biggest hurdle to overcome ( not a big one) is you will have to modify the upper shock mount, or do what I did on my 92 is cut the top shock mount off completely and fab a new one.
in my opinion this is a better alternative than mix matching suspension components from different machines and designs.
good luck,
Scott

Yep, the '84/'87 upper shock mount will need to be cut off and replaced with a new one allowing the longer RPM shock. I have the new shock mount mocked up in a solids design software and a spare '86/'87 frame to weld it on to. Not sure about the FZ1 mods, but it sounds like fun...

Johnnie,
another option, one that I am doing to my newly acquired 84 is to use ALL FZ1 components. I am using the swingarm, relay arm with stock dogbones and a shock all off of a 2005 FZ1. you will have to lose the centerstand but for me, my bike didn't have one....no biggie. the biggest hurdle to overcome ( not a big one) is you will have to modify the upper shock mount, or do what I did on my 92 is cut the top shock mount off completely and fab a new one.
in my opinion this is a better alternative than mix matching suspension components from different machines and designs.
good luck,
Scott
I do have the complete rear end, shock , linkage, rotor, wheel, caliper etc. Do you have any pictures of your shock mount modification? I am curious what it looks like. Does your shock FZ1 shock work well on the FJ? And what to do with this nice RPM shock I have here?

Okay I am going to look at the difference between the upper shock mount on the 84 vs. the 89 frames I have here. I did follow your thread . So you are converting your 86 to dog bones and a longer 89-90 RPM shock?

Here's a pic of my 92 upper shock mount I made
I am logged in but see no pic.

I don't have any dimensions worked out yet but I know I am close to a working design...

Well I am always seeing this gorgeous bike of Pat Conlon's, so I decided to post a picture of one of my beauty queens. This is a 91 FZR 1000, which for me has a long history. I visited my local Yamaha dealer, in 1991. In the mechanic shop was this very FZR 1000. It belonged to the head mechanic, who became a good friend. He only put 1,000 kilometers on it and stopped riding due to health issues. It sat in his basement for ten years. Now it is part of my collection. It had a small oil leak. it was leaking from a plug used to fill a bore hole for an oil feed to the head. This winter that plug was welded and now she no longer leaks. Finally after years of sitting the FZR is back on the road. New tires are being installed as we speak and soon I can enjoy another 5 valve Yamaha.
Also to get to the original point, I have finally finished the YZF front end swap on my 90 FJ. It was to be a winter project ,but I was coerced into doing an Alabama, Louisiana bike trip in February. I am quite happy with the conversion. My former set up was Gold valve emulators and straight springs in the stock FJ forksand an RPM fork brace. It worked very well, but the YZF front seems more supple. Less impact harshness. Funny how the front end seems lighter, which it is ,but I didn't expect to feel it. The forks where set up by Bill Proedhel. I am not sure if I spelled that right, sorry Bill if I haven't. Thanks for a job well done Bill.
Wow, that is one mint classic that is a keeper!
Finally the frame , tail section , etc are at the powder coater. I am doing it all black. I am getting re-started on this bike .

The frame has arrived and the motor installed.

Hey Monkey. If you get to fabing the mount up. Make 2 more and I'll be your first and second customer. For Monkey made upper shock mounts.

Dan, I have a local shop that could quote this part, cut and bent. Might be a bit pricey for a small run of 10 or 20 pieces. But If do then I post a price and see if we get enough interest.
I'm in for 2.

I had the linkage from a donor 89 milled down to mimic the dimension of the pick up point on an FZ1 swingarm. I will have the ability to use a stock FJ shock but will order a length adjustable Penske or equivalent in stead. Once the bearings for the swing arm and linkage arrive the resto-modification will continue. I also have an FZ 1 front end to install. Also we will be visiting RPM in February and will install an XJR counter shaft cover with corresponding shift shaft and clutch pushrod.

The other side of the bike. It's name will be Original Betty. I never named my bikes before , but a friend asked me, if I did name my 90 what would it be. After thinking about it I named the 90 Black Betty. After that song by a band I think went by the name Ram Jam. Or something. My wife heard the name and assumed it was named after an ex girlfriend, Betty. So now all the bikes are named Betty. The 86 was Red Betty, 90 is Black Betty, and now the 84 will be Original Betty. I know nobody cares but it makes me laugh.
Looking good.A remake of Back Betty by Aussie band Spiderbait

Cool, I like that version. Nice video too. Makes me think the name was right.

Now the FZ 1 swing arm is attached. The bracket for the brake switch has been modified for clearance purposes. And for the second time I did not put the shock linkage bolt in the frame before installing the aluminum side plate. So off it will come . I will use my 90's dogbone length to make up a couple more. Then I will order a shock from someone, an adjustable length unit.
