11/9/17- Primary Drive
Today I cracked into the primary drive and found the likely cause of the rattling. The compensator sprocket nut was not even finger tight. Manual specifies over 100 ft lb's of torque. I'm still waiting on the primary gasket to arrive but then should be putting the thing back together and take for a spin. Didn't re-index the shift lever on the inner primary but I think I got it more snug by tightening up everything else properly.
Hopefully with the vacuum cap leak plugged, the shifting tighter and the compensator sprocket and primary chain tightened up the bike will run well tomorrow. Fingers crossed...
