    Polishing the Shift Drum

    I was told that polishing the grooves on the shift drum will help the bike shift easier. Is there any truth to this? If so has anyone done it.

    My last two bikes: '89 Honda CR250R (stock), '89 KDX200SR with PC pipe. See http://www.dragonfly75.com/motorbike/ECtheory.html for full info on expansion chambers and how to design your own.
