Popping out of 4th gear

(1/4) > >>

Gage.record15:
When the bike is accelerated in fourth gear it pops back to third, if you skip fourth and go to fifth the bike continues to run fine under acceleration, any ideas of what this could be? Thanks

Foxx4Beaver:
Sounds like a bad circlip (broken).
There's a very slight chance it could be the gear shift mechanism spring, but probably not if it's only doing it in 4th.  Unfortunately, you'll have to split the cases, and don't just replace the one circlip, replace all of them....on a positive note, it'll be a great time to freshen up some bearings and anything else that might appear questionable.

Thank you for the quick reply, I have the cases split but didn’t know where to go next, I’m going to make sure everything is there according to the book and come back with pictures of anything that might appear worn or damaged, I expected there to be noticeable damage but I’ve learned the transmission is very precise.

Thanks for the video, everything seemed to work just as yours did in the video, I disassembled the two shafts and they have all of their parts and no damaged circlips. I noticed a few things while disassembling though, one being a few gear dogs that seemed somewhat worn, the second being that third gear was stuck on the countershaft, it spun freely but got caught when pulling it off, the splines are slightly burred where the gear sits. I have quite a few pictures of anything else you may need to see to try and help diagnose this problem.
