I just purchased an '08 with 2900 miles on it. The chain has been abused, and is worn out. I'll be changing both sprokets. I'd like to be able to ride at 60 mph on the highway without over reving the engine. Would it be better to go with a larger counter sprocket, or a smaller rear. And can anyone tell me the ideal number on teeth on each? I need to get them ordered as soon as possible. The bike had been in storage since early '09. Battery was dry and dead, carb fairly clean, but the slow jet was blocked with varnish. It cleaned up well, and now runs like a big Swiss Watch Any help with the sprockets will be much appreciated. BTW, I traded my 2010 Tdub for a Harley Sportster...
