Cool, thx for the info. So what combo do you recommend then if I was going to use this chain? I would like to keep the gearing close to the same if possible. This little thing is really winding to do 75 mph. It has 38t on the back right now and I think 15t on the front? Stock I am sure.
Or should I just get a new chain? I got a new replacement sprocket for the front. All I would need then is the rear one and a chain. Or if I go with the 520 conversion then I will need both sprockets.
hmmm, decisions??? Where is the best place to get low cost sprockets then?
