Bike: Genesis gx7 29 inch. Engine: 3hp predator, governor removed with 18lb valve springs. Transmission: Gopowersports torque converter with 10 tooth sprocket #41chain. I weigh 190, average terrain will be slightly hilly.... so my question is what rear sprocket is recommended? My first build and I'm just "tinkering" and having fun but this is the one thing I'm not sure about. Thanks for the help!!
