i have a motor, sitting on a bench, in my basement. calling my name to be rebuilt. going to bore it out, but what should i do? big bore kit? just an oversize piston? you tell me! im only about a year into my bike, and ive put a fresh top end in the motor on the bike, but ive never had to do any machine work to a motor. (take into mind im looking for the least expensive, but most beastly upgrade i can find) so, on that note. big bore? oversize? stroker crank? milling my head? flywheel advance? notes on prices, and actual performance gains would be amazing. thanks guys!
