[QUOTE="75MonteCarlo, post: 1306485, member: 556815"] Oh my lord.. undereducated children. A speedo is a speedo. Don't trust GPS, trust a cop who's also a biker and brings out the radar to a session to meter everyone. And no, it is ENTIRELY possible to go faster than your speedometer can read. Speed is based on engine rpm and gear ratio. You can do all the engine work in the world, but if you leave your transmission alone and use the same gear ratio's, the only thing you achieve is hitting your redline in top gear faster (and if you don't use wider gears, then you aren't going any faster than normal). Engine work + stock gearing = fast acceleration. Engine work + wide gearing = ok acceleration, higher top speed. Engine work + short gearing = massive acceleration, lower top speed. And those axle gears are called sprockets, you increase the number of teeth on the rear sprocket to give yourself shorter gearing (faster acceleration--better wheelies), or decrease the number of teeth on the front (engine) sprocket for the same effect.
