Has anyone else experienced really bad performance when riding a passenger? My bike seems to want to cough, spit, sputter, missfire, etc. It runs pretty good with just me, but as soon as I take someone for a ride it performs horribly. I am looking for a fix. I am riding a 2000 X1. I have a Race ECM, Forcewinder Intake, High Performance O2 Sensor, White Brothers Slip-on Muffler with 18 discs, and a Power Commander. The Power Commander is Zero'd out since adding the Race ECM. Problems existed with the stock ECM, remained with the Power Commander, and still happen with the Race ECM. I need some help.

Bob...have similar set up with different components (check profile). No problems like you describe with or without the Techlusion DFO dyno'd with the Race ECM. However, the bike is much smoother and I swear cooler running with the DFO.

You may want to head back to the dyno shop and get the A/F ratio calibrated to with your Power Commander. I know I have to after some putz messed with mine thinking he was some sort of motorcycle tuning guru.

Thanks, I guess I'll have to take it back to the dyno shop.

The only thing I have noticed, when riding with or without a passenger...

It seems to to wanna backfire and cough @ the most inconveinent time, , like trying to make a turn through an intersection, then bike will buck and surge....

Or when trying to take off form a light....

I dont know if its loading up....

or what...

My 2 cents...

maybe the passenger weight is touching some wires together or pinching air hoses or something. At the buell homecoming a couple of years ago, a buell would run great when it was him only, when his wife, (small would get on) it would die. found out the weight on the back was shortly a wire. Once that was corrected, it ran with both riders on the bike....rex

I saw an S3 pilot who had a simialr difficulty with his smallish passenger -- turned out to be a wire getting pinched, but only when there was the extra weight on the bike -- (same deal as Rex is remembering) -- tough, if not impossible to diagnose with no one on the bike . . . . .

Check the "web" ground cable, where it hooks to the frame, above the swingarm.

...and the tip-over sensor which is (I believe) in the end of the tail.

I had the same problem when I took delivery of my 99 X1. The wiring harness (near the swingarm) was getting pinched due to weight of passenger. Rerouted harness and repaired break in wires, no repeat problem in 15k miles.
