i put an HRC header and Baffle insert... Thy say thats about equal to a slippon....I just bumped the main to a #140 and it seems spot on. i race xc so i leave airbox alone.They say if you open box you can go to #160?

ok well my prob is. I got a motoworks g2 full exhaust race mx and airbox lid will be off and they guy at motoworks said to put a 128 main and needle 5th from the top. which is suppose to be for my elevation 1425 but i think it still sounds lean. im not good with jetting. what do u think
