Hey everybody, Im new to this and have alot of questions, but my biggest one is whether or not to use a jackshaft. 1st how long will the standard bike chain hold up? and 2nd on alot of videos it sounds like the rpm's are constantly oscillating giving a weird exhaust note. Any ways I wanna go 30 mph, and I wanna go up hills. Am I better off with a jackshaft, or spending the same amount of $$$ on performance parts. Btw its going on a 26 beach cruiser
