Patriots,
Quick question regarding the Gear Shift Drum Guide. The large screw-nut & inner assembly atop the upper crankcase, that helps you find neutral when shifting. After a parade rest take down & rebuild this part was giving me some issues. Namely when assembled, it would seize up the shift mechanism. When uninstalled (not present) the mechanism would shift as smooth as milk.
Through some trial and error, I determined the problem was the screw nut (#17 in the pic) was the issue. I did this through isolating each part to see if they independently had the seizing effect or as an aggregate. When placing the nut it by itself (without the spring, lock washer, and o ring) it would seize the shifter.
I placed an additional washer (roughly a 1/32 -1/16 of an inch) on in-between the lock washer and the screw-bolt. The bike still shifts, (although it is stiff) and I can find neutral.
My mantra with modification is "if it works & doesn't put you in danger it's good to go." I doubt this slight modification would have an impact, but I wanted to run it by the Round Table first.
Thanks Team
(as a side note, the spring is still strong & straight & the ball bearing appears completely round ((I tested it by moving it on a mirror to look for any wobbles or other imperfections)) the o-ring is fine)
