ok i got a zx636. stock gearing is 15 front and i think 40 rear. its ok but i want a little bit more down low. what do you guys think of a 14 front. how bad do you think it will hurt my top speed. i keep hearing ppl going -1 front and +2 rear but that has to hurt top speed. plus i dont want the thing to go 12 oclock if a slam the throttle in 2nd gear.
