I just got a '01 650r and was wondering: 1) I have a spare wheel set for my 04 CRF450r (I run an 18" rear) - Obviously the front won't fit but will the rear fit my 650? 2) I need to order a tank and don't really know the fuel range of this beast. Is the 4 gallon overkill for dez racing (only using this in the bitd series) or is the 3.2 good enough? I have never had a problem with the 3.2 on my 450, I can get just over 80 miles at race pace and just over 100 puttn' around. Thanks in advance.
