I know about the FST but I don't wanna go over 400cc.If I do that I have to race in the 450 class.

Well with out a cam or port work/oversized valves u wont get nearly as much of a gain. I can't really say for the warrior we have put them in 400EXs and standard ones in many quads; have not had a customer come back yet with a complaint. I would guess probably a 60% gain... the FSTs put out almost a 100% gain (around 40 HP + total depending on mods and port work).

The cam depends on what you’re doing. I like powroll's midrange high lifter for trailing it’s got a nice duration, they make a great race cam too that is suppose to be nasty (haven’t tried it). The staff at powroll is more then willing to talk to you - give them a call they will help you out with general info/cam selection for what you want to do.

go to fourstroketech.net to look at the kit, the kit itself is $649 for the 446, but you're looking at a lot more than that to get it installed if you can't do it yourself.

I have a question too.

If I were to get a stroker kit like the ones yall are talkin about, will it cause the engine to overheat easily and will the engine have to be rebuilt soon after?
