2004LEBanshee Posted November 10, 2003 Report Posted November 10, 2003 For going to a size larger main how much do I adjust the air screw. Also which way do I turn it. They have never been adjusted. What are signs that they are set wrong? currantly 230 unifilter and no snorkle. going to 240 Quote
BenBB Posted November 10, 2003 Report Posted November 10, 2003 You may or may not need to adjust them at all; they fine tune the mixture from idle to about 1/8 throttle. So if you have a bog or hesitation right off idle (and the mains are dialed in), adjust them in (richer) or out (leaner) a quarter or half turn at a time. I'd see how it runs before adjusting anything... Got some more info in the Jetting FAQ if you want to check it out: Jetting FAQ Quote
ZigZag Man Posted November 11, 2003 Report Posted November 11, 2003 my air screws were too rich (bog or doggy when you take off) all it took was slightly more than an 1/8 turn (out or ccw) oh and BenBB is THE SHIT when it comes to jetting Quote
