Yes it is stock, but if/when I need to do engine work I would like to build it up a bit and thought that changing the sprocket size now would be the way to go. It seems to be geared pretty low, would like a little more speed before having to shift and higher speed with lower rpms while cruising the interstate.

Yes it is stock, I am having to replace the compensator sprocket and clutch assy now and thought this might be the thing to do. If/when I have to do engine work I would like to beef it up a bit.

Serious HI rpm woes...
I got tired of the 70mph-3000 rpm zone but didn't want to sacrafice acceleration and torque at low end so I made a few changes. For performance purposes I replace the primary with a belt drive from BDL (i believe its a 45 front and 68 rear) which did change the ratio a bit but also took a lot of weight off the crank allowing torque an hp to be transferred to the rear wheel with less loss. I then changed my rear sprocket from 65 to 70 again changing the final ratio to a 3.31:1 but by installing a 6 speed I was able to achieve a 70 mph-2450 rpm zone. I now have a very quick and comfortable ride for all types of riding. Worth the change.
