I’m sure hoping I can find some help here. I have a 1990 Fourtrax 300. It had been running great and then was parked. Went back the next day to start it and it wouldn’t go into neutral so I couldn’t start it. Loaded it in my truck to have it looked at and it went into neutral. Was able to shift through all the gears with the motor off. I went through the gears 4 or 5 times and then it stopped shifting again. I have pulled off both right and left side covers and all gear shift components are good. After I got it apart, I was able to get it to shift through two gears and now it won’t shift again. Could this be a bent fork? Hoping someone can shed some light on the problem.
