G-Man, is there enough room for a 16 or 17 tooth drive sprocket on the 305? I really am looking for a smooth ride verses off road use. Woody

Honda only listed 13, 14 and 15 so maybe not. I would think that 16 would be alright. People are listing 17T for these bikes so they ought to be OK, too.

I just tried a 17 tooth sprocket I picked up on ebay. It fit the shallow spline just right however the tips of the teeth on the sprocket will not clear the kick starter shaft. Also the larger diameter of the 17 tooth sprocket jams the chain into the engine casting. I guess I will try and locate a 16 tooth sprocket I think it will just clear everything. WL
