3 rear teeth on the rear sprocket usually equates to roughly 1 tooth on the front. Front sprockets have less impact on chain length than rear sprocket changes. So usually going 1 up or down on the front is better unless you really want to fine tune the rpm. Sent via BlackBerry by AT&T

I went the other way and made the rear sprocket smaller. I dropped 3 teeth, almost 1000 rpm less at 70 mph. made a big difference in gas milage and the engine isnt working so hard on the freeway.

I was thinking of changing mine as well. It feels like the engine is working too hard at 55+mph On Wednesday, November 21, 2012 8:05:29 PM UTC-5, Spanky wrote: I made the change on my '03 Nighthawk. I can run 400-500 RPM less than with the stock gearing. I drive the interstate to work & surface streets going home. I get 40-42 MPG. -- You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group. To post to this group, send email to [email protected].
