Finally, it seems I found my solution! The Suzuki service mechanic suggesteď me to turn Traction Control Off because that interfere with gnition... as I feel it helped!
We could also tune the cable slack a bit but during the next service it will be adjusted.
TPS was checked via computer diagnostics and that was good.

Am I reading this right that you are checking the TPS adjustment with the engine off??

You will adjust the TPS with engine not running, but with the ignition key turned on.

Interesting.... I'm curious of the source of these directions, and sort of wonder if an important step was left out.

The procedure for the SV650 is very similar, but with a warmed up and running engine. (shut off to jump wires for dealer mode) While getting engine to normal operating temp, adjust idle to 1200 RPM. The "-" sign should be in the center of the display. Advance the throttle very slowly, and it should jump to the top at 1450-1500 RPM. The 3 bikes I adjusted were all at 3000+. back off the screws a bit on the TPS

At that point it was a T25 security bit to back off the screws so the TPS (sensor with 2 screws, one in an elongated hole) can be moved with some resistance. It's sensitive and you have to move it in very small increments, sort of a trial and error check, re check.

I haven't checked my Strom yet, but I will be curious to see what it does running vs stopped.

Bighammer-

Hmmm,,, I guess I dunno if "engine off" is correct and I might have done it incorrectly. It seemed logical to set with the engine off, so that's what I did. I do know my bike sure runs much better after the adjustment per the method I used.

the plot thickens.

My service manual would suggest but doesnt explicitly say engine off. However, i have read other forums/models where they were setting the TPS at different rpm's.

This is an interesting discussion.

For controlling idle rpm, does anyone know if the Vee 2 & 3 have a IAC (idle air control) valve? As opposed to an actuator which physically opens the butterflies? IAC circuit bypasses the butterfly and is most common in automotive systems.

If these bikes have an IAC, then the butterflies will be completely closed whether the engine is running or stalled, and the TPS reading should be the same in either situation.

I have also read that (during throttle movement) the rpm when the middle dash in '-C00' changes to high counts as well. DL1000 shall be around 1200-1600rpm ideally, 650's are higher a bit but defenitely not as high as ~3500rpm.
This transition probably makes changes to engine control that makes the throttle reaction not so smooth at low rpm:s in my reading.

To be able to check this transition you have to have the engine running. This can be a kind of a fine tuning after the getting to the starting point (-C00).

Also read that TPS should not be sensitive to temperature. So does not matter whether the engine is hot (running) or not.
When the TPS gets sensitive to temp. it's not working correctly anymore.

Without practical experience I do not want to say the truth, just tried to summarize my knowledge I read about this topic that I'm also interested in.

Thanks, I turned off TC and it did help the snappiness throttling from idle.. kinda sucks you have to lose TC to smooth out the throttle
