So I got an 1988 Ninja 250 that has turned into problem after problem.

The bike doesn't want to shift right. I can pull in the clutch and put it in to first or second. but I can't shift the bike up with the clutch to third or any higher gear. The only way I could shift to third or forth is bike letting on and off the gas a bunch of times and trying to shift hard a bunch of times.

I am thinking Shift forks are messed up.

Any ideas. Or something could be put in wrong again since when I took apart the top end someone at one point put all the intake valves on one cylinder and all the exhaust valves on the other one. I duno what other SMRT ideas they had for the transmission.

Thanks
 
When's the last time you changed the oil?
 
Oil

When I got it. since the carbs flooded and leaked the the cylinder walls. so there was a lot of gas in the oil as well.
 
ideas???

I am about to rip down the motor all the way.
 
1) How many miles on the transmission?
2) Is the clutch cable actually disengaging the clutch? Test: Put the bike in 1st. Pull in the clutch. Can you roll it around the garage? If you can't roll it around, then adjust the clutch cable. There's too much slack.
 
Pull the right cover and check the pawl mech on the end of the shift drum. A simple tip-over in the garage against the shift lever can fuxor teh whole assy. Easy fix tho. Good luck. :|
 
I would first check clutch engagement (doubt youll find anything since 1st and 2nd is good)

My bet is shift forks and dogs
 
thanks guys.

I'll check it out tonight. Motor has 2,400 miles on it.

with a wet clutch and a cold bike that's never easy to do.
 
Agreed, but you *can* roll it. If you can't roll it, then the clutch isn't disengaging.
