Which Motor?!?

[Mick]

Suicideneil - thanks for the response.

I just bash, but enjoy the odd speed run ;-) I mainly use the buggy on concrete/tarmac in the winter and short grass in the summer. I want enough torque to pop the odd wheelie, while it still being driveable! Also looking to break the 40mph, closest I've got is 36mph running 16/48, on 95mm diameter road tires. I just feel that the stock motor is weak and needs more power. I don't know if thats because its a 2 pole or what?

Any advice?
