Anyone have encounter wz the gearing...
Problem:
1. Is it true when u kick into 3rd gear but it stay at 2nd gear?
2. When u kick into 4th or 5th gear(when u the RPM nearly hit 10)...all of sudden it drop by itself to 3rd or 4th gear...

All this i encounter during my trackday .....

No. Can't say I do.
Are you doing clutchless shifts?
Is the track bumpy in the area you're trying to shift at?
What's the condition of your shift ratchet inside? There's the wheel that rides over the detents of the shift drum. If it's worn or damaged somehow, it could be allowing the drum to rotate up or down.
