Time for my annual post dogging the Guzzi fuel system! Ok this year I have the stock air box back on and it ran decent most of the winter. Now its getting hot outside and after 10 minutes the bike is fully warm, it starts missing a little between 3-4k rpm. I think we are lean again. When I had the air pods in place the surging in this range was horrible and unsafe at times. It was diagnosed by a lean condition caused by the air pods. Now its much better with the airbox, just a little miss. The real problem is when i'm pulling up to a stop light or stop sign. The rpm will drop down to 5-600 rpm and try to kill the motor. If I blip the throttle a bit it recovers and will usually idle around 1400. It has died on me a few times in this situation but always starts back up. I have the idle set to 1400, a little high but i'm trying to keep it from dying.. TPS is set, carbs are synched, had my mechanic do an 02 analysis during tune up. I'm still thinking the stock fuel map is to blame and i'm trying to reach Todd at Guzzitech for a reflash. But i'm wondering if these two items might factor in to my problems at stops signs/lights.
1. Air bleed screws, i'm at 3/4 a turn out. Any further out and it gets leaner. What would running them in do to the idle speed?
2. Throttle cable is loose at the intake assembly loop. The only way I can see to tighten is at the twist grip and the cable adjuster is all the way out. Maybe the cable is stretched and in need of replacement...
Love to hear any thoughts, ideas, or curses.
Thanks,
Toby
