I just synced tb's and fuel mileage dropped. Heres a little history till now. 2005 busa with 9000k full synth,rs3 full exhaust and pcv. The bike had a little dip in cruising speeds 2800-3500 so I had it dynoed last year. It ran a little bit better but was still there. I changed the plugs and it also helped, but still noticable. Above 4k it goes fine but since Im in town alot it was driving me nuts. So this year I synced the tb's they were like 4 cell bars low to high right hand to left(sitting on bike). Tps is in the middle. I changed the air filter with a new oem one. I take it out for a ride and its running
perfect, no dip in cruising speed throttle response smoother all plusses except I notice my gauge dropping fast 22mpg as compared to the 35 I have been getting and bike is running super rich. Really strong smell of fuel, no leaks I checked. I checked the map and it still the one that was tuned to. I put on a zero map just to see. Now the fuel mileage is climbing back up. Do I need to get it re-dynoed ? Try the tuned map again and run another tank of fuel ? All hoses are connected and tight, pulled air box just to be sure. Would a new filter and a tb sync affect it that much, they were really out of sync when it was dynoed, I now know. Afr was 13.2 when tunedif that helps. Let know what you guys think, thanks.
