Ok, well I can definitely say I'm new to this. I'm looking to upgrade my 400ex without having to out the bore kit in it. I was reading a dirt-wheels forum when i came across something that interested me. I want to put an 11:1 Ross Racing Piston kit in the 400. Now the quad is stock other than a full dmc alien exhaust that i just got. I have a filter/airbox coming too. And i was wondering if i could put this kit in it without having to purchase any other aftermarket materials: cams, etc. ***And, where can i buy the pistons at??***

thanks for the help!!
