I need some good references to where I can get a larger carb, engine mods, and I want to know if there is a divice that I can get that will force air into my motor instead of suck. I don't know what that "AirForce" kit is that you guys keep talking about. Fill me in on mods that I can get to make me faster. I have already lowered a front sprocket for MX, White Brothers slip-on, K&N air filter, removed airbox snorkle, and cut a massive hole in my box. I'm looking for like a turbo charger or fan that will force air in the motor, high compression piston, and hot/high rev cam-shafts. I know Rath Racing is in the making of all that but they take too long. I also wanted to know if any of you have ran higher octaine and felt a difference. Info Info Info please! I'm desparate to eat up every quad on the MX track including 250r's and I need more power to get the holeshot on Banshee's and 250r's. Thanks!
