RPM unstable

06 Wee, while riding today, I noticed while stopped and at idle, the RPM were bouncing between 1100 and 1400. Never noticed that before.

Had the valves checked at 17K 6 years ago. Shop was sketchy, so assume it was done, I had started but couldn't finish, was over my head service wise, had it towed in already stripped down

Now at 36K

Idle set at 1300

What else might cause this if not valves

TPS or air leak come to mind.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s
See https://www.stromtrooper.com/general-...nicknames.html

Its not the valves. They don't change rapidly and all of a sudden.

Throttle bodies out of sync, vacuum leak at one of the rubber boots on the intake tract, sticking throttle cables, TPS worn out ... someone else come up with other/ better suggestions?

I've got an 04 with 96K miles and an 05 with 36 K miles. Neither has ever done any thing untoward in regards to idle or running. The 04 runs like a swiss watch that uses oil. The 05 sits and waits for a license but starts and runs smoothly after setting for months.
i find it curious that an 06 can suddenly become non functional unless in the process of the valve check the mechanic really goofed something.
Hopefully in the hands of the dealer it will become the Wee that just works well if left alone.
My 04 went from 23K to 80K miles with nothing more than oil and gas with a mechanic making a small change in one valve at the 80K mark.
Better left alone that overworked perhaps?

I seem to recall my 2006 DL650 doing something like that when the battery terminal was a bit loose (or was it bad battery?)

2006 DL650: 202,000 km 125,500 miles, Sold
2012 DL650 139,500+ km, 86,700+ miles. Sold
2015 DL1000 New July 2015 180,000+ km, 112,000 miles.

This can help preventing from cars pulling out in front of you (SMIDSY)
SMIDSY detailed report.

Check the rubber nipple covers/plugs on the throttle bodies. I think there's four. When I did my first throttle body sync I found a couple were cracked. I replaced two and did the extension tubes on the other two to make the throttle body sync easier in the future. The sync turned out to be right on.
