Rub on Ya Titties
Hi Guys
Working away on an old basket case motor rebuild. Removed the shift fork assembly and i found some interesting / concerning wear.
There is this obvious crack in the case. It's not gone right through, but it has distorted the case where it protrudes near the front sprocket and is very close to the needle bearing for the shift drum.
Secondly, when i removed the shift drum i found this wear pattern at the other end. Ive already ordered a complete and good used fork assembly plus a NOS needle bearing (and my shift forks were pretty wasted). Im investigating case repairs.
My question is: wear like this on the shift drum, what would cause it? Could the case be bent slightly causing the drum to move out of alignment from the crack? Or is it just high miles? It doesn't look normal too me
