Running rich, sluggish under 2k
So I am at a loss here, my bike just randomly started to run kind of rough under 2k rpm. It feels sluggish, lack of throttle response and throughout the entire RPM range the exhaust doesn't sound quite right, it sounds almost muffled. Details on the bike and the day it started below.
2015, 16k miles, woods 555 cams, thunderheader, power vision (fuel moto tune), stage 1 air cleaner, new plugs and wires. We installed the cams over the winter and I have since put about 2-300 miles with no issues. Checked the crank runout at the time of the install and it was only about .003" well within tolerance. Run only 91-93 octane in it, unless the station does not carry then I run 91.
I got gas that morning and we rode about 40 miles before stopping for lunch. Once we left it stated falling on its face going up hills and occasional backfire out the pipe between shifts. I ran about half a tank out, put seafoam in it and filled up at a different gas station. No difference so far. The only engine codes I seen were running rich in both cylinders.
Thunderheader, Woods 555 cams, Power Vision, Sony radio, Rockford/Hertz speakers.
