ok ive been gone for awhhile but some may remember me. anyways i am really considering to bore out my 99 wolverine to a 400. what would be the best cam and piston to go with the machine. and what would give it the most relability and performance. i would like to hear some comment before i get it done. later

 

I've talk to four stroke tech. about their 435cc kits and they told me that it will increase low end because of the added stroke of the crank. They also told me the cranks they use are alot lighter than stock which helps it rev faster. They recondmended a mild cam for slow trail riding and the race cam if riding faster trails. I have rode a freinds warrior that had this kit with the mild cam, and copared to stock, the thing screamed. It pulled great from idle to wide open. I would have to think that the wolverine would have to respond likewise. As far as just boring it, I would not think it would have as much low end power, but it depends on what you want. His warrior had the 11 to 1 weisco piston and the .390 cam from white bros. As far as reliablty, he had this warrior for three years and never had any problems. Like most, he got older and slowed down to 4x4 quads, but the motor is still alive and well.
