Actually you need to ditch the 4-stroke....

 

to each his own. Preferance and riding style. I've ridden 4 strokes since my little Honda 50 when I was 7 and it just works for me. I've ridden 2 strokes but it's such a different riding style to me and I'm not any good at it. Not to mention even though it's the proper way to do it I don't feel comfortable sliping the clutch on a 2 stroke all the time I feel like I'm burning it up.

 

Shane Blazer is right, get a carb and a pipe. Then cam and valves and spank some raptor tail.

 

I dont know about spanking any rappy tail but it will be alot faster!!!
