Potential shift shaft problem
I pulled the motor to replace the stator cover gasket. When I was trying to remove the cover, it was hanging up on the shift shaft/seal. I sprayed wd40, then pb blaster with a 20 minute wait, both with no effect. I finally resorted to prying between the case and cover with rag wrapped wrenches while tapping on the shift shaft (tapping increased in effort as aggravation set in). It would move about a 3rd a millimeter at a time, but came off after about 30 minutes of work. When I put it all back together, I noticed the shaft had about an inch of inward travel, which I assume is a dislodged snap ring. My question is: what potential damage might have been done while "tapping" on the shifter shaft? I know replacing the thing will require a significant amount of work, so my goal once the bike is all put back together is that it shifts. But if it doesn't.............?
