hello again, I have been looking for several different things for my 99 prairie 400 and have been having a terribly hard time finding many parts for it. I have managed to find a K & N air filter but thati s about it. I would really like to find a pipe and silencer that will fit it and also a clutch kit and am taking suggestions to any other mods to get as much power as i can from it i don't quite have the funds for a 650 yet so i gotta make due with what i can. So if you could please direct me in the way of some websites or even phone numbers that i can get ahold of peopel to find some of these parts. thank you for your time

 

Mickey Dunlap has a lot of answers to the P400. Mickey owns Fourstroke tech and has mods for the P400. www.fourstroketech.com I bet if you emailed him, he would be very courteous and helpful.

He can bore it to 500cc, and possibly sell you performance cam. I bought a stiffer secondary spring for a 400 from EPI. You could make the 400 really fly if you wanted. There is a dynojet ket if you think that it is needed.

Have you checked Dennis Kirk for exhaust? You could put a custom fit HMF silnecer on it yourself. You could try the easy "Nyroc exhaust Mod" or the more technically difficult "1bearman exhaust mod" (see my website, prairie 650 section for details).

I vote you go with the 500cc kit and cam from FST and then see if you need exhaust.

Alltoys has turbocharged his 650, I bet he could do your 400.
