[QUOTE="mmackie1969, post: 1325678, member: 100898"] Im in need of desperate help. I just bought a 01 yz 125 and the head has been re-sleeved and bored out .20(54.50). I can hammer the throttle and the low and mid range is good but when the power band hits it "blubbers". I can turn the fuel off and when it starts to empty the carb bowl it takes of like a rocket. It has a 420 main jet in it now but i need some advice on what size main jet i should buy now to fix this problem. Thanks. [/QUOTE]
