big bore kits give you power..
run a 14 tooth fron sprocket with a set of 18s.. mike razrs or holeshots.. or fast trackers... remove air box lid, get a set of boyseen power reeds or vitos carbone petals.. there like $20 bucks.. and get a few bigger jets, change everyhting and jet it up a little like 240 or so... you can allso remove the end cap of your stock silencer and remove the cone inside, keep cap off.. guys said it give aslight increse in power since your opening up the flow a little bit and sounds a lil nicer
