Gents,
Running into an issue with a newly installed tri-spark set up on a ‘73 850 Commando. After a complete rebuild the bike looks great and runs well.... kind of. After setting the initial timing on the tri spark the bike will start relatively easy. However after I shut the bike down, the rotor (containing the magnets) drifts out of place from the taper fitting in the camshaft causing a loss of correct timing. I’ve cleaned the contact surfaces, torqued the bolt that provides the taper fit down pretty hard, tried to shim it... etc and no matter what the rotor still shifts out of time after shutting the bike down or extended idle period. Somewhat stumped and wondering if anyone has seen this issue before?
Thx,
-John
