Hay guys I'm at the point of a total rebuild starting at the 2nd gear replacement and moving up.
I'm taking the line of a street bandit pic i'm sure we have all seen.
(https://s-media-cache-ak0.pinimg.com/originals/6f/fe/db/6ffedb3e3538bd257580ecc86e78c992.jpg)
can you guys give me some thread/links for engine rebuilds specifically cylinder swaps and bore outs, just need to see what's available.
My valves are all shot to shit, and i'v got to fix 2nd gear, and while i'm at it I might as well see what kits are available

The only engine kits that I know of are from Andrews Motorsports in Concord, North Carolina USA. They do offer shipping to Australia. There are currently 5 kits available. from mild to wild, pick your poison. Three kits are plug and play drop in kits while the larger two will require modification of the lower cases. A fellow FJ owner installed the 1380 kit and had the pistons modified to lower the compression ratio to better perform on pump gas.

Fred much appreciated will have a look through and see how I go, prob looking at the 1297 Kit however Might get the current head Bored here in Aus to save the cash.
As you mentioned in your reply up to the 1297 were straight fittouts yer no lower end work required?
Ta
Fred Been through your rebuild that is awesome.
This is the same build that I'm looking at I hope you dont mind me racking your brain during my build.
Say your clutch what is it a slipper clutch? and that window who did you get to do that Very nice?

Part of the reason I went with the Andrews 1297 kit was the custom cylinder sleeves that they use. With their sleeves there is no modifying of the lower cases. For oversized pistons, the general rule has always been. You can
Bore the existing sleeves up to 1219cc's without resleeving and no modification of the lower cases. You have to resleeve starting at 1250cc's, using off the shelf Wiseco sleeves and pistons. The lower case has to be modified to accept the larger sleeves.
Another reason that I went with the complete cylinder and piston kit is that the precision work is already done by a very respected company that is well known within the FJ and Legends community. I had a very bad experience trying to get a FJ head re built locally a few years ago.
There is an Aussie or two that have big bore engines. Hopefully they will chime in on what they did.

I have a slightly modified OEM clutch. The RED pressure plate is from A.P.E. and I use Barnett heavy duty coil springs. I have installed the wide inner fiber disc mod, along with the RPM Roller Shift Detent kit.
The clear clutch cover is a one off cover that I purchased from an XJR1300 owner in England.
Fred
Nice one looking at the UK XJR Sites Now Gonna Have me 1 of them.

NICE :)
I just rebuilt my engine to FACTORY specs over those big bore kits after I did my research.
Every macho fuck out there wants a big bore kit. Big piston big power right?
Only if you get the airflow right.
The trouble is your compression increases way above factory and now you have extremely turbulent air
being sucked in your cylinders. You must now change the carb slides to compensate for the fucked up airflow.
If yo choose a 0.5mm or 1 mm oversize piston your motor stays within factory design specs and you dont need to
mod ur carbs.
A 1000 japenese engineers designed the FJ1100 motor. One mechanic with a big bore kit can fuck up how your engine runs.
Sure you might get more power but overall the tourque and powerband curves for big bores are not the same as factory.
U may have more power but a fucked up tourque band and weird running bike.
Its your engine though so have at it.
Skier, tell us more.....
Have you had a bad experience by which you base your opinion?
.....or are you just guessing?

I am not sure where you looked for your research. Randy Raduechel at RPM, Curt Andrews at Andrews Motorsports and Hank Scott at RRC Performance Engines are world class FJ engine builders. Both for the motorcycles and the Legends race cars. I NEEDED to rebuild my upper end due to massive oil consumption. I did not open a perfectly great running engine just to get a few more ponys. I did my research and determined if I was going to open the engine to repair the oil consumption, why not spend a small amount more and get a plug and play Big Bore kit. Your assumptions of a bad or funky running engine is WAY off. Obviously you have not read my engine build thread. I have over 10000 miles on my Big Bore engine and it runs and performs as if it rolled off the showroom floor yesterday, with some extra punch included. You need to understand....adding CC's to a FJ engine is no longer an experiment and has not been for many years. Randy, Curt and Hank Scott have the big bore builds down to a science.
Let me explain how close theses engine builders can get. I purchased my Big Bore kit from Andrews Motorsports, I installed it myself with the guidance of Randy @RPM and a few other forum members. RPM jetted, adjusted and installed a set of Hank Scott adjustable needles in a new set of carbs for me in California, based on my intake, exhaust mods and elevation in South Central Kansas. Literally, the very first time I pushed the starter button to start the engine, it fired off and ran. The only adjustment that I had to make was the idle. In closing....I bought my Big Bore kit to cure horrendous oil consumption and I got an everyday rider that no longer consumes oil and has a wicked punch whenever I crack the throttle a little extra. Am I happy with my Big Bore build....You bet I am, Do I think I would have been better off doing a Yamaha spec overbore? Not for the money involved.
Sorry guys....end of rant
Fred
You tell him Fred. :good2:
"A 1000 japenese engineers designed the FJ1100 motor."
Isn't the "Japanese engineered" carbureted 1999-2007 XJR1300 the same mill? If so, we're not doing anything different than the Yamaha engineers by increasing displacement.
http://www.motorcycle-usa.com/2014/10/article/2015-yamaha-xjr1300-first-look/ (http://www.motorcycle-usa.com/2014/10/article/2015-yamaha-xjr1300-first-look/)
"...The XJR1300 got its first life when Yamaha bored-out its old 1188cc air-cooled Inline Four to 1250cc for the 1999 model year and it's been going strong ever since. In 2007 Yamaha added fuel injection and throughout the years the Tuning Fork brand has tweaked here and there to meet emissions standards, but for the most part the powerplant has remained unchanged."
:Facepalm:
hmmmm..."skier..." created his account March 13, 2017, 01:22:01 PM. First post is pretty nasty. Did we not ban a guy like this a while back who then created another account and then proceeded to insult everyone, until that account was banned as well? Just sayin'

LOL!
A big bore by itself will usually improve your torque curve!

I doubt there are 1,000 engineers working for all of Yamaha.
Fred said "I can't post a question about requiring, new members to pass an IQ test before joining the forum". So I am not posting this as a question, just passing along what I was told.
Kurt
Holy Toledo!
Hmmm, let's see.... there is Brutus I've seen down in Tennessee, the Wizard down in the San Jose area, Mr. Conlon down in southern California, another California southerner from Semi Valley, Fred from Kansas, apparently some fellows from down under and of course the Giant Killer from somewhere up north....
And no doubt a host of others who got it all wrong...?!
May I suggest that CutterBill has it right... there is no argument!!!
We have heard this opinion before on our FJ forum. Something along the lines of "Yamaha's got it right, why mess with it? Why modify anything? 17" rims and modern radial tires will fuck up the handling of the bike...etc, etc.."
Ad Naseum.
While several specifics of skiier's post are inaccurate, I noted that he used "you might" and "you may" in his statements....He did not say "you will" an important distinction.
I do agree with him on a couple of points.
1) slapping on a big block without knowing what you're doing will end poorly. About like a monkey with a machine gun. (not you Marcus)
2) compressing the added volume of displacement into the same squish area will result in a higher compression, yep, that's true. You've got to have a plan to address that, especially if you're running Kalif. piss water pump gas.
3) if you are pulling more air into the motor, you must address the airflow...i.e. add more fuel. Proper Jetting is critical.(not the slides skiier, the jets)
4) power and torque will not be the same as factory. Yep, that is true.
5) you might have more power, but end up with a fucked up torque curve and a weird running bike...
Very true. With the improper selection of cams, you can have a bike that howls at the track, yet runs like shit on the street.
Skiier's overall premise that "you can't go wrong if you stay with stock specifications"
Boring, but true. Kind of like ordering vanilla ice cream when you can have Cherry Garcia.
That said, I sure enjoy that RPM 1380cc engine, fucked up torque curve and all.
A man's got to know his limitations....and some thing's are best left to professionals.
Sincerely
Macho Fuck.
.... and there ya go... I did learn something - again on this site. Very informative. My mildly modified FJ (brakes, suspension, exhaust) has so far been seemingly indestructible with its stock engine - even in my hands. It's good to know that when the time comes for an engine rebuild (at this rate maybe when the sun explodes) I can get it rebuilt with a big bore kit by an experienced engine builder (maybe by that time even myself... :scratch_one-s_head:?) with confidence that it will function as good as stock.
With an engine design that's going past 30yrs old from the FJ-FJR-XJR series - like many have said - the engine components, quality kits, and specialists available have a proven track record. This ain't the 70's where you pays yer money and takes yer chances. Dyno tests are no longer the exclusive perview of race shops. They are readily available for anyone now to tune them properly.
Maybe skiier did have a bad experience with a big bore kit on a previous bike, or on his "FJ". I would guess IMHO it's not the failure of the big bore kit but the improper application or subsequent abuse of it.
I also learned do not Google search for images of Macho Fuck. Definitely NSFW! :bad: Seriously Don't! Trust me! :shok:
That bad eh, Paul :rofl: :rofl:
Oh God, and I had to go look without thinking :Facepalm:

Oh my god im sorry I didnt means to offend your sensibilities.
Jeez doesnt matter what the fuck one says on social media someone is always offended.
I didnt say anyone was stupid all I meant was do your own research and understand why things
are done the way they are.
Ask randy why yamaha changed the slides on the carbs when they upsized fromm 1100 to 1200.
Stop being so easily offended.
GO FUCK YOURSELF.

I dont know everything but I have an engineering degree and I can read.
Why dont you ask your experts why yamaha modded their carbs when they went
from 1100 to 1200.
All I was saying is factory specs are generally more reliable than aftermarket.
Dont be so easily offended youu little girl.
(popcorn) (popcorn)
Well now that you asked: According to Randy, Mikuni (not Yamaha) changed the carb slides (flat bottom to curved bottom) in 1985, about 1/2 way thru the production run of the 1985 FJ1100's. In other words, the curved slides came out when the 1100's were still in production.
If I had a wish, I would wish for an IGNORE button on this forum.
