I own a 2002 mxz 600 adrenilne. *it has 144 studs and a MBRP performance exaust pipe. I've hit 96 mph at the radar runs *(2000 ft) but it won't do any more. My second problem is a *96 formula 3 600. *I eat him alive in 2000 ft but how do i stay ahead on the lake, his machine slowly creeps up on me only because I've got studs do i stay ahead. I am a fairly agressive trail rider so he's no compition in the trails. what can i do

Have you tried w/o the can? They are supposed to help, but I have heard of cases where they have hurt performance. As far as the FIII 600 on the lake, I think you are doing well to just stay with him as long as you are. Triples have longer legs than our twins.

I have a 99 mxz600, w,96 studs & mbrp, mine only goes about that also. *Sometimes I can get her over 100. *I can hang wit Stiemy for a while and he has a mxz7 w,reeds,mbrp, & clutch kit. *As for the F3 *he will get you but shouldn/t be by much on top end.. http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/smile.gif

Yah I guess i'm doing all right but I also want to know about some mods to put on it that won't be a waste of my time or money. Anything that works would be great! Anybody?

One more thing, *Steimys bud has a 99 MXZ600. *I ride wit him once in a while,, * He ported his, *shaved its head, *reeds and a few other little things. *My can keep with his too. *When I drove it I couldn't tell much difference in his & mine. *The only thing I would do that would be worth anything would be a clutch kit. *Try Goodwin, *there supposed too be real nice. *Nick *http://www.snowmobileworld.com/forums/iB_html/non-cgi/emoticons/tounge.gif

Cudney's kits for the 600 work pretty well too..I've never used one, but I'd check them out, their pretty close to half the price..
