For kmd. I didnt mean that rebore i bull im after simple changes like exhausts? im used to 2strokes,power valves and DEP pipes etc. Im told that the xtc has a Suzuki engine so ive been looking for a race pipe to fit wiv no luck. Any idea the cost of the rebore as ive considered gas flowing but like the rebore i dont want to take it that far yet. Maybe i should just go for a bigger bike,save me writing all this shit. Cheers.
