I've been riding my x around on the street with the stock gears, well rear is a 49 i think, and its way too short. Anything above 50-55 it starts winding out. What size sprockets should i look to get, if i want to be able to cruise at 70 for highway use. I dont mind if its just starting to sing a lil bit at that speed, just so i can go along with traffic almost and not get ran down... If i went +1 in the front over stock do u think that would do it... or would i need to drop the back down as well to a 44/45...?
