Heck yeah do both!!! If you have the opportunity to change it all out for the better, why not! While it is FRESH on your mind, figure where you would want more response from your throttle, and build that into your mod. You can get neck bending torque, or eyetearing top end out of your scoot. the roller weight will change MOST of the performance. You do not need to tune the clutch as much on a larger scoot. The multivar will give the tuning you want. Heavy rollers will give you a slower, more even throttle response. Lighter rollers will give a quicker response, with a fall off at the top end. Either way I say GO FOR IT!
