I'm going to ride Baja on Dec.4th on trailboss tours and I will be riding my own bike. I was wondering if anyone had any suggestions on gearing and tires. I was told to go with one tooth larger on the counter sprocket to gear it taller. I ride an 03' crf450 most of the time, and since I'm 6'5" tall and 220 lbs. I'm running heavyer springs on my 450. does anyone have any ideas what I should run on my XR650? thanks in advance for any info.
