6 bucks ebay
a 225 dx thtree wheeler 4 poke and the moto 4 are the same engine wich turned into the timberwolf from 90 to 99 . then it was renamed the bear tracker ..same to 02.
i have a 2 225dx three wheelers 1 i made a timerwolf motor fit on it ..bolted up but the drive shaft had diff end ...
what did you need to know about the quad as long as its one i am firmiliar with .. as diff from 225 dx and 230 timber wolf used a 1mm bigger piston . and from what i think you can drop a wiseco 225dx 10.25:! compression piston right on the timberwolf/wolverine/tracker but you have to either use a 1mm oversize pistion and a standard jug .or swap cyl or a sleave for a 225dx.. the heads can interchange somewhat unshure when they are different. 95 up you can run a cam from a 350 4poke warrior in em hot cams on ebay are like 125.99 cheap ...that and upgrade the exhaust and you can push pull and drag shit around ]
