[QUOTE="CHET, post: 665017, member: 46102"] The increase in bottom end power will be very small if you can notice it at all. The port height must be lowered to get more bottom by turning down the base of the cylinder. Of course the head would then need to be modifed. The new CR motors just don't have the port layout for bottom without some major surgery. Add a couple of teeth to the rear sprocket to help the roll on and out of corner responce. [/QUOTE]
