Well, I got an assortment of jets on the way ranging from 340-290 I will start high and work downward. I also heard the k&n filters are not ideal for dusty conditions. So I think I will just remove the entire airbox and just put on uni foam pods, seein how I will be removing these carbs alot to establish proper jetting. A buddy of mine said that I should replace the stock impeller ASAP w/ a billet one, Do any of you guy agree or dissagree w/ this coarse of action? Damn it, are those jets in yet?
