Where the heck is the procedure for setting the A/F screw positions? I know that a dyno or an A/F meter is the best way, however I thought I recall a procedure to get you close for those without access to these resources. Since waking the bike up after it's long winter nap I have had a backfire/stumble during decel and when running at low throttle positions. The bike starts and idles well but when moving the constant backfire is fricking irritating (it is also hard to look cool when your bike sounds like Chitty-Chitty-Bang-Bang). Did both the shotgun and peashooter this weekend. I didn't catch any significant particles or massive gunk in any of the circuits but what did come out was really orange in color. Continued to push carb cleaner until it came out clear. A/F screws looked OK, not super gunked up but there was a little goop on the end of the screws. Drained the bowls and the fuel was clean with no particles or sediment. Set the A/F screws back to their previous positions but I think that with the circuits cleaned out the ratios might not be what they were before the cleaning. sooooooo....anyone got a link to the procedure? My google-fu was weak this weekend.
