I missed 2nd gear and revved past 12k, now i've got a new sound...

Sorry it was not my intention to ignore your good advices based on your knowledge and experience. It's just that I assumed the worst based on the noises I got. I'll do a 25 mph 10 mile limp to the shop to have the bike checked. I was not able to get a clear recording of the noise as it was impossible to hear on the playback.

Here's a vid. When I put my fingers on the front sprocket while turning the rear wheel I could feel the clicking. But there was no play on the axle.
I had a short testride and the noise was gone. But something didn't feel right when cornering. I have little experience fixing motorcycles, but is this noise normal?

A good mechanic could pick your problem in 10 ft, but if you don' t have access to one of those you are stuck with internet advice based on your description.

A noise that only happens while accelerating and with the weight of the bike on the road is unlikely to be replicated on the stand spinning the wheel. Your suggestion that it felt funny around the corner still points to a problem in the back wheel, be it the carrier bearing or wheel bearings.

Don't be fooled by bearings that feel smooth when turned by hand either. Unless literally falling apart, shot bearings feel smooth without load on them.

I couldn't hear anything unusual in the video, but that means little, I'm half deaf.

Keep us posted.

I have to warn you .About 25 years ago I had same symptoms on my 1100 i ignored it and one day my backwheel locked up in a lefthand corner and i crashed i was lucky as speed was low.Just seconds before that i was in high speed...
It was impossible to get the bike in gear after that.I had to come back and pick up the bike in a van. and the gearbox had to be rebuildt with a new second gear sprocket.

^^^Good advice. If the tranny locks up, pulling in the clutch lever won't help you.....

[motorider17]

Thanks for your advice. Friday I will have the bike checked by a mecanic. He have been fixing Yamahas for 30 years, so i'll post the results. I will leave the bike at the shop and get on the bus to get home. Hopefully it's a small job.

I'm glad to hear you're getting it looked at.  Good luck!

[motorider17]

The shop lubed the chain and had a test ride. Bike appears to be fine and they advised me to change oil and look if i can see any metal chips. So it looks like the biggest problem was inside my head.

Glad to hear another old FJ is still on the road.  Hey, treat her with a little respect.  I short shift thru 2nd and really don't push the engine in any gear.  Damn, our bikes are 33+/- years old.... that's like 231 in dog years!

Until you change out the soft oem shift forks, sure go easy in second gear....but FJ's (well maintained, well tuned) absolutely love living in the kookaloo zone.

They are most happy when they are singing their 8k rpm song. They are amazing engines.

To ensure a "positive shift", you should upgrade to the RPM Roller Shift Detent Kit. The kit uses a roller bearing detent lever and a stiffer spring for that quicker, more positive shift to make sure the transmission cogs get engaged properly.

The early shift forks were not "soft" so to speak, but they were much shorter than the current forks which allowed them to flex and disengage the cogs.

Thanks for the tip, looks like this is what I need. Appx. How many hours is needed to fit these?

Its worth each cent!. Miles better that the Factory shift kit. Soft, precise, positive, there is no risk of losing a gear when riding hard. One of the best improvements that I´ve done to my FJ
