Sticky choke?

[Clauscbf]

Sticky choke seems to be a common Transalp problem.
My 650 has a sticky choke I think.
How do I test to know for sure if the choke is det problem?
I do not want to take the choke apart at this stage.
I got the bike back from 12.000 km service on friday.
I drive my TA every day.
My TA is 15 months old, will this be a guarantie issue?
Ideas please?

Not common? What are the symptoms?

My dealer told me so after the 12.000 km service.
Black deposit inside the muffler.
Start without choke even at 0 degrees celsius.

I have a complete Arrow exhaust including header, KN-air filter, original main jets. Fuel consumption, 17.5 km pr. liter fuel.

Maybe this is normal?

Shouldn't they have fixed then?!! Just check its operation, pull the choke on and then off and check that its releasing at the other end.

I would be surprised if it was faulty at that mileage. And there will be black deposit inside the exhaust anyway! I would check the colour of the spark plugs, they should be light brown - if they are, no problem. I would expect it to run leaner with k & n and arrow? You may need a re-jet?

That's 50 mpg! Completely okay. What mileage do you get out of a tank?

[Clauscbf]

Usually I have to fill 16.5 liter after 280-300 km.
I drive mostly to work, a lot of stop and go, so maybe my choke is OK.
Thanks for you answers.
