JB weld hey, does it hold up to gas? I can't weld the pipe to the stock part of intake because it' cast, and pipe is steel. My buddys scoot gps's at 42 all the time, and he ran 42 by the trap. Maybe it reads me better because I'm 6"1 and 220 lbs and not in any tuck? Anyways the hopper kicks the scooters ass bad!!!!! HA HA
