Number of Shift Drum Rollers
Posted: Tue Nov 26, 2019 2:22 am
I am closing the cases on a 250 narrow case single and suspect that I don't have the recommended number of rollers on the shift drum. The motor I am trying to bring back to life has 13 rollers that only complete about 3/4 of the drum circumference. A parts engine I also have had 15 rollers. What is the recommended number?
