sprokets an stuff

Thanks gents I will start planning to renovate the mounts and get this done it sounds exactly like my problem.

btw I had a spare 15 mins this morning so I changed the 18 tooth front sprocket to a new 17 tooth, I went with a genuine Yamaha cush drive one, quite nice  the bike is different with the 17 tooth sprocket, don't know yet if it's good different or bad different, certainly picks up quicker.

One thing I did notice is that the old 18th tooth sprocket is hardly worn after 20,600 kilometers guess the Scott Oiler, despite being a right PITA is doing its job.

I have grabbed a bit of inch water pipe and have started building the puller to do the motor mounts, prolly get around to it some time next week

'92+ bikes have fully rubber mounted engines if memory serves me.  I seem to remember others saying the lower engine mounts on those years also seize up.  David R. said it was a PITA to get them out, but once everything is cleaned up and working the way it should, almost all the vibes were gone.

Yup... the difference is dramatic.  There are pictures in the gallery section under Misc FJ Photos.  And David R. documented the process well. It's worth the effort.

Anyone here running an 18t front, and a 42t rear on a stock FJ swingarm?
What length chain do you get? How many links?

I can tell you that with 17/42, 110 links...  it just fits, gotta put the chain on the wheel before inserting the axle, and chain adjustment is very forward.  I think 112 links would workout about right..

I'm currently running that exact combination on my '85.  Using the standard 110 link chain.

I'm using an 18/42 combination on my '91 with stock swingarm and use a 112 link chain.

My 86 runs lovely with 18 up front to give a bit more swingarm clearance and a 46 on the back.
According to the marvelous mechanical gearing calculator (to be found in the files) - 18/44 leaves things pretty close to the 86 standard of 17/41 (1 tooth on the front change equalling 3 on the back) - this was the case or so it felt. Anyway, went for a little lower gearing since we've great roads here near Napa.
I like the difference - quicker, obviously when trying and an added bonus of livening up 5th gear enough, so when you're just wanting to be lazy you can stay in 5th and the engine does the rest. I suppose it's a little more buzzy at interstate speeds, but I try to avoid that kind of riding if possible.

Oh nearly forgot - my advice.
The guy who works for the 'sprocket center' (google it) was really super helpful and has a chain link calculator. They sell DID heavy duty things - pricey but worth every cent for peace of mind. The sprockets they sell are all steel which is meant to be the way to go - mega strong if a bit heavy. Recommended.
