if you ride it and it doesn't sputter or hesitate at full throttle, then you should be ok for one ride. keep your airbox lid on also. but when you get back, you should do a search on here and see what jet others are running for your mods. adjusting your fuel screw won't affect the main jet, just the idle and deceleration. you may have to go up on the main to a 128 or 130.
