My '13 stock CB1100 doesn't run as smoothly as it should and I know most don't have this problem but some of us do. I might have found an answer, and I don't know if this will work or not (I haven't tried it yet) but I'm going to soon. I found this on the Concours Owner's Group message board. One of the guys there was complaining about rough running and he got a reply: "Sure sounds like the TPS. Turn the bike on, do not start it. Twist the throttle on full, roll off full, do it twice. Turn off bike, turn back on and start. Go for a ride and see if it works. Report back and tell me I am a motorcycle god, or worthless POS
FWIW, this works on GSs that have a similar problem with the TPS, ECU will read the full on/off position and do a rest to the current values. Same holds true when calibrating the PCV or PCIII."
Here's a link to the entire thread if you want to have a look:

Yeah. That works on BMWs, I wasn't aware of other brands.
Two comments- roll the throttle slowly when opening and closing, and, if this reset
clear things up, it's not immediate. It may take a 30 or 50 mile ride before it clears up.
That worked for Suzuki DL1000's and 650's, except it's 5 throttle cycles for them. It really does reset the TPS. If the bike starts running really rough after an hour or so, you pull off, cycle the ignition, do the reset routine, restart. and they'd run like new again.
Unfortunately the TPS Suzuki used were a high-failure part. Apparently most TPS have a copper path to that's a friction contact that wears and/or gets dirty. Eventually the reset wouldn't work and you'd have to replace one or both of them.
I tried it yesterday then took a 35 mile ride. It seemed smoother but I honestly don't know if it's my imagination or not.
I wonder if this procedure or something like it is listed in the shop manual?
My Triumph Tiger 1050 had a similar TPS reset procedure listed in the factory service manual.

I just tried this and I sincerely believe it works! (I actually twisted my throttle to the stop three times). I immediately took my bike for a short, 10 mile ride, and I could feel a difference the first time I let the clutch out leaving the driveway. My bike runs better everywhere below 3,000 RPM, and gone is the stuttering (mis-firing) between 2K and 3K at light engine loads. I am not going to question how and why it works, it just did on my bike. Maybe it has something to do with this being the first time the throttle on this bike has ever been twisted all the way open and the TPS needing this to recalibrate? All I can say is a great big "Thank You!" to mininsx!

Dave i know you have been having issue, glad the bike feels better. I tried this myself for the heck of it and did notice the bike pulled out of the hole a bit better with 1/4 throttle inputs. Glad it work out and hope it holds for you.
The bike does have 4 TPS sensors, and it's not uncommon for this to happen.

You're welcome! I wish I'd known about this little trick sooner.

I'm glad this worked for you Dave. I've been following your travails with interest. I'm surprised the dealer wasn't aware of this procedure.
