a few years bak i put on two throttle extnsions, one for oil and one for gas. they were big and in bulky and also i was not able to go full throttle and it pulled my oil cable too much and i was using alot of oil. also where the oil cable enters the box, it frayed it and good thing i saw this before i was riding bc i gave the throttle two blips sitting in my garage and i saw the oil cable break. just buy cables from r.s.i to avoid hassle
