Want a kick *** quad.

[Gatorman199]

I was wondering how much it would cost to get a 11:1 piston(and would it make that bigga prefermance diff). And can i just drop it in or do i need other things? Help... i want to make my quad able to rip some ***... i want to stay under 1k. ONLY ENGINE MODS. I want only things that give it more power. Any suggestions will be appreciated. I already have the usual, jet kit, exhaust, air filter. WHAT ELSE?! BTW how much would an oil cooler cost and can i just pop that on too?
