Default Re: Shifter Bike Freewheel Skipping?

GhostO, Thanks for the explaination. This skip is under throttle load, riding down the road. It has nothing to do with shifting. It is a momentary free reving of the engine. I just completely dismantled the entite G4 unit, absolutely nothing slipping in there. I did machine me a new shaft from a piece of 5/8 jackshaft. The original one was mis-machined and had horrible run out, the bike surged at high speeds. The new one runs true and I replaced the sprocket with one like is used in the shift kit. Should be smoother now.

Donutguy: Im really thinking freewheel now, going to pull a rear wheel off one of my other bikes to see.

NT to down shift I just blip the throttle and shift down. If I am coming to a stop. I just down shift all the way to first while moving pretty fast, with the auto clutch you get about zero engine braking, so there is not much point in shifting down through each gear. I shift twice on the downshift to 3rd, then 1st. I can do this at cruise speed.
