Ok i have a 1988 250x with the modds listed in my profile.. or album or what ever that thing iz... Im looking to at about 10 more horses out of the bike.. Im pulling like 31 right now.. i would LOVE in the 40 range... If i add a Stroker crank to the bike and A sparks Ignition system that lets me rev out to 10,000 will that get me where i need to be?? also what size crank? 4mm, 6mm? or what powroll sells the 12.7mm stroker crank.... I dont have a problem sending the engine out and getting the cases cut to fit it or anything like that but i need to know what kind of power i am looking at here? and iz it worth the trouble??thanks... also anyone know who i would have to sent it 2??
