Thanks for the input RC and the Aleman:
I have been looking for a rear disc set up, but I am not sure what to buy. My bike is a Huffy Big Daddy and will have the stock single spd rear hub.
I have been toying with the idea of getting a 7 spd rear hub and new rim with 12 guage spokes.
I have also seen on ebay and PistonBikes.com an adapter that does away with the rag joint, bolts to the hub and then the sprocket bolts to the adapter. Do you know if anyone has tried these adapters?
My bike is due to be delivered by UPS today!
I bought my engine kit from Pistonbikes.com, I ordered last Thursday and got it yesterday! It was well packaged and nothing was broken. I intend to order my air cleaner and other parts from them as I go along.
