Hello all, I've riden in the past and now I've got my own. I recently just bought my first dirt bike The XR650r. I've gotten suggestions here and there about getting the most preformance out of my bike. I've gone from a new muffler and then into jetting and now the last thing I want to do for a while is change my sprockets. Could someone give me there opinion on what kind of sprockets I should use on the front and the rear to get the most tourqe uot of my bike.
