I am currently riding a Stanton Inc friction drive kit with a 1.34 " drive roller with a 63cc kasei 2 stroke.. I just don't get enough top end with this size roller and I have been using jb qwik to increase the diameter of the roller.. i am topping out at about 40mph which is perfect.. but I'm tired of using jb quick as it it's not permanent ..Does anyone know where I can get a larger diameter drive roller say 1.75 or 2 inches that will fit in this Stanton Inc box.. or someone that can make me one?
