There is a equipment store called "Northern Equipment" , they have a department in there under "go-carts" . In there I found parts that can apply to us MBers , such as heavy duty roller chains , sold in 10' lengths, #41-1,which fit both drive side sprockets nicely. Priced for only $14.00, so its like two for one! Also they have cables, throttles, and safety gear! A good place to go visit for your own experience, if the chain store is in your area. Most of us are do-it-yourselfers , so go ahead and pickup a catalog while you are visiting! Thanks.
