I`ve never seen anyone use nitros on a small engine, but all the guys I know useing it on cars say dont over due it and it will be fine. Like you dont take a stock small block 350 and add a 400 horse nitros kit. 100-150 would be acceptable without probs. The same would probly apply to a quad engine.

 

Why do you want to risk (a very real risk) grenading your expensive toy??? If you want rocket thrust, just go get a ported and piped Banshee. My Raptor is fast, and I love it...but my Banshee will leave it for dead in a drag. Sounds like you needed to buy a super-mod 2 stroke to start with! Each type of engine has it's strong points...enjoy your Raptor for the strengths it possesses.

 

i seen a kit for gopeds, they got that thing to do 63mph, i have had a lot of experience wit n20 and i have seen a few back fires mostly due to driver stupidaty, i am thinking of putting a wet n2o kit on my raptor and i think a wheelie at 75 would be bad a$$ , but it has plenty of power already,pipe it and pro flow it ,and if you get to where you can ride it wide open in ever condition,call duncan and tell them to fire spader cause you will be the fastest man alive, i still scare myself sometimes with this thing, its not the fastest quad i have ever owned but it makes its power diffrent than the others i have owned

 

DUDE

You are asking for major trouble...get a pipe high compression piston and mess around with the jets...my frined had a VFR500 interceptor and he blew it up when he put the nitro kit on
