I just got my 88 250R with 310cc kit on it. So far the motor runs great but I suspect a water leak or oil leak - maybe both.

Other than that, I have difficulty shifting into 3rd or 4th, sometimes 5th and 6th.

It downshifts just fine, but it wont go up into 3rd or 4th. Sometimes it will after waiting like a min or 2 in that gear at cruising speed then it'll finally go. Sometimes it'll just go right in no problem.

I also noticed that if I gun it then shift, it doesnt want to. But if I go easy then shift, it is more likely to shift.

Any of this sound familiar to you guys? What do you think my problem might be? I plan on pulling the motor out to replace the crankshaft collar and seal on clutch side, as well as the mechanical seal. I hope to find the problem with the shifter while in there.

I'll bet you the problem is with the transmittion, you are looking at some money to fix that, though. New gears are expensive, also the gears tend to take out the shafts.
