Alternative Rotor Bolt for CB750
« on: July 31, 2018, 05:14:42 PM »
We milled the rotor on my Salt Flats motor to use as a retainer to keep the starter gear intact. We have no shortened the retainer to within a few threads of the crank-end. Would like to locate a bolt with more threads toward the head as a replacement. Any suggestions?  I will check my CB & CL 77 parts bin.........maybe CB340-450?

Are you going to have enough threads in the end of the rotor to use a puller if you ever need to remove it??
Don't fix it if it ain't broke!
