Ok so its like and outerwear pre filter kinda deal. Idk what to tell you then does it smoke real bad.

not at all its very clean burning, you really have to get on it for it to smoke. It has a Hot rod injection pump (vp44) make a difference?

have you thought about it having a somewhat high gearing, and big ole tires. big tires means big rolling resistance.
