I'm new here, but I hope you guys can help me.
I have just purchased this bike and it was sitting for quite a while. It did not run when I got it. I have changed all fluids, replaced spark plug, disassembled and cleaned carb, and replaced about 20 bolts that were missing. I got it running great, except for shifting. It seems hard to engage in any gear. And the most concerning is that it slips out of 4th gear. If you want 4th, you have to hold the shift lever up???? And also with reverse, if you do not hit the throttle quickly, it does not stay in reverse????
Any ideas on what to do, I really don't want to have to split the cases if i don't have to
