Low speed/rpm fuelling? Good or bad?

Hello All
New to the forum, and considering a BMW G310GS purchase! I will be swapping my Honda CRF 250 L for one if i go ahead

My question/concern is this:

How is the bike at low rpm? Is the fuelling good? Bad? Average?
Are there any engine cut our issues - at all - or, at low rpm?
I like to ride low speed technical type off road, and on road - not that i am any good, but i like to practice this type of riding in the hope it makes me a safer and more competent rider
Can you u turn the bike and practice cone work with the clutch out, and the bike on tick over, or with very small throttle openings - sometimes, balanced on the back brake? If you do this, is there ever likely to be an engine cut out issue?

On this subject - has anyone fitted a "Power Commander" or made any other fuelling modifications?
Can you adjust the idle speed? If you can, how do you do this?

Thanks in anticipation of your help

No power commander for our bikes....yet, some people have changed their exhausts.

Clutch work is the name of the game with the 310, it's geared rather high and will cough stall rather easily.
Lets be clear : this is no Trials Bike!

You should read Jmo who is completing a summer of testing the 310GS in adventure mode and has tested some gearing change.
She is testing the Rally Raid mods but is not obnoxious about it, plus she does have credentials since she has done some Dakar raids and done some terrible things with her Honda CB500X.
search for "JMo" here and on ADVRider.com search for "Beemer Beemer chicken deener"

What bbbelanger said. It's a lovely bike for puttering down a back dirt road and maybe some light single track, but the gearing is aimed toward road use. That is easily changed and sprockets are becoming available (a source named in another thread on this forum).

Thanks MichaelJ.
I have a W650 - it will easily u turn in first with clutch out on idle, or maybe a little throttle. Is that because it is a larger engine? Gearing? Carbs as apposed to EFI?
I'm no expert. There is a Bikesocial video - a bike gymkhana and he rides a G310GS - he learns to ride between the cones with clutch out just using throttle and rear brake - i ride this way often. Am i strange?

Me again - the thread was on ADVRider - not here.

Relevant info for sprockets from that thread - evidently in short supply :

"The 15t sprocket is ordered from KHS Bicycle Parts....KHS Bicycle Parts
The Esjot part number for the 15t front is: 50-32184-15S
The Esjot part number for the 41t rear is: 50-32050-41
You’ll want to talk to Betty @ 618-393-2955. I have warned her that she may be getting a few more orders."

Hello, and thanks MichaelJ.

Very helpful

A common modification on the CRF250L is to change the front (and maybe the rear) sprocket, to make the gearing more suited to trail riding. I have not altered mine (i have a CRF250L), as i also use it a lot on the road. I can feel that there would be a big gain for off road if i did change the sprockets for sure

There have been a number (albeit a small number - due to parts availability (or lack thereof)) of people who have swapped out the countershaft sprocket with the 15 tooth and have reported a significant improvement of low speed behavior with too bad a hit on top speed on the road.
