Thanks for the info Jim.

I have a Walmart Schwinn Point Beach 7 speed with a ZoomBikes 66cc 2 stroke and a Sick Bike Parts shifter kit on it. I want to use a pull starter and need wider crank arms for that.

I just ordered a pair from "GasBikeShop - RuiHong Enterprises Ltd." I'll find out how well that outfit does business soon enough. They were $28 with the shipping.
