If it gets worse check your emissions solenoid (if you have a CA model)


Leopard, I know you want to help, but please don't give any advice. You don't know what the fuck you are talking about. The emissions circuit deals with fuel vapors...it has nothing to do with what the op is experiencing. You need more knowledge before you start giving advice.

I'm asking you please, this time....
1) Free Owners Manual download: https://tinyurl.com/fmsz7hk9
2) Don't store your FJ with E10 fuel https://tinyurl.com/3cjrfct5
3) Replace your old stock rubber brake lines.

Well, rode out to the ethanol-free station today to put some hi-test in with a bit of Seafoam. The float hasn't stuck since my last post, and didn't do it today. However, I think I am losing second gear. Bearing in mind what you guys said on the matter while I was out today, I paid closer attention to my shifts when going into second. It definitely is having trouble shifting into second gear at higher RPMs, and though it's not popped out of second on me just yet, I wager I should still nip this in the bud. I wonder, though, if I should just get new shift forks from RPM, or if I should go ahead with the whole undercut transmission, shift forks, detent roller, etc. I'm not afraid of spending a few hundos on the bike if it'll give me a better riding bike in the end, but I still am curious just how far any of you FJ veterans would take this issue on your own bikes.
Try not. Do, or do not; there is no try.

The second gear issue is not a "maybe" condition. If you are in 2nd gear and pulling hard, 6K+ in the RPM range and it pops in and out like a revlimiter then you have a 2nd gear issue. If you can redline in 2nd gear then you do not have the dreaded problem...

It sounds like you have a bent shift fork , but 2nd gear has not rounded the dogs off yet.

you could put a shift detent kit in it and get a few more years before doing the gears and forks , but that would mean always shift into 2nd below 6k rpm.
This is what I did for years knowing my forks were weak and it sucked riding the fj having to baby the 1st to 2nd shift all the time. Makes is tough mountain riding twisties .

To replace the shift fork you have to split the case to get to it, and the gears are right there anyway . Might as well do the whole thing.

This is where I am at now with my FJ . I am kicking myself for not doing it sooner . :dash2:

Some members have only replaced 2nd gear and wish they had done the whole gearset the first time when they end up having to do it twice cause another gear goes bad.

So if you like to haul ass and do high rpm shifts and blip down shifts and generally ride with your hair on fire do the whole transmission gearset with 3 new forks and detent kit. You will be set for a very long time.

If you are more of a pleasure rider with occasional moments of rippin and grippin then do just 2nd gear fork and detent kit and cross your fingers.

I would highly recommend doing the whole thing with the super beefy shift forks that Rpm Randy sells. Thats what I am doing. :good2:

I had this problem years ago and all i did was clamp the fuel line and run her out and restart with choke full on to make sure.
Then i opened the screw on the float bowl and used a rubber pipe, held the throttle wide open and blew through it with a compressor.
Never had the problem again. Give this a try and see what happens. Good luck
