I just put my HMF S/O on, and I changed to a 125 jet. it still sputters a bit right on top, I turned the air/fuel screw 2.5 out then went some more and it helped some, but how much can I screw it out before changing the jet size again?
you are absolutely correct and i don't know how many threads i have read suggesting that people adjust their mixture screw.Originally posted by twgracer@Jul 6 2004, 01:15 PM
The air fuel mixture just changes the low end. If it is sputtering on the top, you need to jet up.
