Could some of you verify and help me determine which sprocket sizes would make my 2000 650R go faster on the highways (lowering rpm's) Stock is 14-48 and my local dealer rep said more teeth while my friend and other on line seem to be reducing teeth? I purchased another stock 14 for the front as well as a 15. I am under the impression that one tooth in front is equivelent to four in the back. Anyway, I would like to go faster without reaming the motor on the expressways. Thanks for the feedback.
