hope to get some help from you guys..... ive been reading and am having trouble deciding. i want to get a lil more response out of my bike and am thinking a new rear sproket is the way. ive been to the drag strip a few times and enjoy that, but im mostly a weekend rider. bikes plenty fast as is but i want a lil more on the take off. i have factory sprokets now, tell me what i need to get to keep my highway speeds as high as possible and wheelie in first and second.
