Just an update on this: Thanks to Dave's kindness, I installed my .45 jet. I did no adjusting to anything else on the bike. I think the pilot screw is about 2 turns out right now. The bike is running much MUCH better now. I felt a slight hesitation in the throttle that was so minute that I questioned if it was just in my head or not. I rode the bike about 27 miles and it only cut out and spit back through the breather once (as opposed to once every 15-30 seconds before). I think that the hesitation and random spit back can be adjusted out. Any suggestions?
