Go slow and you should be fine. Adjuster screws come in two diameter sizes from local bike shops. Aim for the smaller diameter and settle for the larger if you grind too much.
Stock throttle cable is the wrong length for the thumb throttle. I followed Norms post but I think after I I hooked it up to the thumb throttle and left in a neutral position, I made the other end 49mm off from the cable housing.
yeah, that's what i figured. i'm sure i can rig it. and i've got no probs with shortening the cable. i'm using compressionless "Jagwire" brake cables now, modified to fit.
thanks for the info...
