Even the original Honda 50 (C100) had a problems with the shift levers coming loose do to lack of maintenance. I've even seen it on bikes without the heel shifter.

As far as maintenance, sure...you can keep tightening it as you slowly destroy it (by misusing it) and eventually you will need a new shaft.

Yeah. Once you stand on it once or twice and screw the shaft up or twist the shifter arm, or oval the shift bushings, or destroy a pressed joint, it is definitely going to need maintenance.

Try putting some liquid threadlocker on the splines after a good cleaning and ideally while new. Red is the toughest and hardest to remove...takes some heat sometimes. Companies like Permatex also make bearing mounting liquids but I have no experience with that particular product.

Ok thanks for the report. I've used it but not over a long period without reapplying. Maybe their bearing mount stuff would be better. But I can see the problem when there isn't full contact around the full circumference plus the constant vibration and pounding. Plus the metal's probably poor quality to begin with.

we have tried this..stuff works great on stationary bolts but the constant back and forth agitation over time and slow erosion I believe is the culprit for it losing its grip. I guess pretty much have to take them apart periodically, clean, retorque then say a little prayer

thanks for the great information..this problem has perplexed us for a long time...weird thing is I do check tightness from time to time, and can never get it to budge..feels like it'll snap if I continue...then they have been know to inexplicably fail anyway based on our experiences...hard to trust and have confidence in...was about to JB Weld the *****' $%#^ and have them torch the shaft off if ever needing to work on the low end...bottom line is keep a close eye on them which I do after first hand experience failing on the road..if and when it does I'll probably just try out the Better Lever product
