do you want to go faster then him acceleration wise or top speed wise?

[mikeysnide]

top speed wise, like in a drag....im a lil better of a rider than he is and were both light guys so id like to get him but i really dont think im gonna be ale to..i just didnt want to go with the 460 kit in mine cuz i ride mine every weekend trails, sand...ill ride whatever i can

if i was you i'd do a 440 with a cam of your preference and a 450r carb. You should also get oversized headstuds and a heavy duty cam chain though to to keep you motor reliable

You also might want to look into getting a new clutch and basket to handle the xtra hp

hey man thanks for the insight, i dont have the extra cash right now ive done dropped a grand on it so far...thank god for tax returns huh lol but i found a edlebrock carb for it for 380$$ and they said its dyno tested for 7 hp...but i will check into the chain and studs thanks again

you'll have to put hd studs or you will blow it
