hi i just got the new atv and four wheel action mag and there is a article with the raptor and had big bore kits availeable from Bike Worx. they have 673cc,686cc, and 724cc big bore kits . the stock engine is about 38 horse i guess but with these kits it can go from 48 all the way to 75 horse! (depending on the compression level) all make similar top end power but alot more on bottom to mid power. all you do is call them at (978) 897-0044 and then send them your engine with about 2000 to 3500 bucks. Pretty hefty price. they have stock bore high compression pistons too for 325$

 

do they have a website?

 

Just for imagination purposes that's one scary thought. I think that all the Raptor owners can see where I'm coming from on this one. Wicked...
