popping out of 2nd and into 3rd. The guide pins on the shift forks have some wear on them. Wondering if its hanging up on the shift drum. Can't really see if its hanging up on the shafts. will this wear cause this. I have the cases split and am shifting this by hand and watching the action. Couple of gears have some wear on them but it looks like the problem is smoothness with the pins and drum groove. thanks wil.
