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!!
 
Welcome to the forum, I haven't built a bike using a predator but from the people here that have some where from 36-41 is the usual range. I have a 26" bike with a 66cc two stroke with a 38 tooth rear sprocket, I ran a 41 for years which gave more bottom end. With 29" wheels you'll have to experiment a little.
