Why are the pipes on my XCT sooty, but the plugs are not? Weird.

Under wide open throttle and when accelerating our bikes run excessively rich, cruising they run lean. You can't read plugs anymore because with engine load and throttle position, even the smallest change will put you into a different area of the OEM map. I've watched it on a wideband O2 sensor air/fuel gauge I had mounted on my bike. Acceleration, WOT soots (sp) up the back of the bike and cruise doesn't making your plugs look good.

Every Victory I have hade runs rich. I have had soot marks on the Cantina garage door for years. The 03 Vegas was the worst.

Only joking....gasoline used to contain lead, when it did and an engine was in tune, then youd get a nice grey pipe!
No more lead, no grey pipe.
Ride hard anyway

Put 80,000 Trouble Free Miles on my 2012 Victory XC Full Stage II.. Plugs and End of Exhaust Pipe always Black but never was a problem unless wanted to think it was ..
Evidently you had a or some very competent mechanics that did the work on your scooter.

if you come back here go buy aftermarket spark plug wires and OEM plugs. It will help your bike run smoother

Thanks, but my bike runs just fine. I replaced the plugs and wires a year ago. LMYR
