Regarding your transmission, what did you have done? Did you have some of the dogs undercut? Only modification I ever did to the transmission was I put in hybrid ceramic bearings. I always felt it shifted better than any other bike I've owned. It takes very little effort and just a small tap of the foot to shift up or down. So I'm curious if others have done under cut to improve things even more. I've never hit a false neutral or popped out of gear.

If I were to someday build another motor I might consider cryo treating things then microblue coating. Probably not because it's gonna make me go faster, more because I would be interested to see if I could get just a little less friction.
