Running Way Too Rich!
Damn! I just put on a new exhaust system on my '03 VTX 1800R. It's a Freedom Exhaust Combat 2 into 1 system. Had to replace some old Roadhouse slip-ons because the welds on the baffles on those kept breaking! Anyway, new exhaust might as well be a flamethrower it backfires so much! Bike is running way too rich. I have more of an open air hypercharger on it with K&N filter and PowerCommander III USB. I have leaned out the PowerCommander to it's leanest settings on the unit itself and cleaned my K&N filter (it did need it) and still no good!? I can't do any other mapping on the PowerCommander because I don't have a Windows PC. I'm tempted to just try getting rid of the PC III, but it looks like I might have to get a new, stock wiring harness if I do?? The bike only has about 9000 miles on it and other than this has always run perfect. Any suggestions would be greatly appreciated. Thanks...and Happy Holidays to all!!!
