What should I do to my bike? I currently have a Vitos 240 with a 3 mil stroker crank, a mikuni 36mm carb, and a FMF gold series fatty pipe and a powercore 2 muffler. I was thinking about rebuilding my Vitos kit and getting the head ported. I was also pondering getting a Vitos fat bastard pipe. Should I do this or go back to a stock head, get it ported and keep my FMF? Also, if I were to go back to a stock cylinder, could I keep my 3 mil stroker? Lastly could I bore out my Vitos kit and get a custom piston and rings? Which would be the best, and which would be most reliable?
