I just bought my first mini bike , there's hope for me yet ! It's a sears roper. It doesn't have a torque converter or a motor . Can I turn the rear tire around and run it the other way , seeing how there is no torque converter ? I have the sprocket that came w the bike and some 35 chain . I was told the 3/4 shaft horizontal motor is what came w these bikes . Also what motors can I use for this project ? Thanks
