    Buy a CRF250? or get it bored out and stroked. Port Polish, Cams, High Comp piston, thers tonnes you can do with them bikes

    You could change the gearing for better torque. Or add some modifications like exhaust+a larger cylinder. I think you should just get a 250 though.

    I really would not bother with the bike you have as it is not really the fact that it is a 4 stroke but that it is a basic trail bike and not designed for power. The crf150r is the racing version and would have all the power you could want. Invest in one of those and save the money for that
