Issue with an F800GS Idling when warm

Hi, I have recently had my F800 GS valves reshimmed and after reassembly the bike starts and runs fine when cold but after getting riding it and getting the engine warm its won't idle properly and seems to run roughly at low revs.

I have tried resetting the TPS but then starting from cold and idling there is no issue.

Before I go mad and tear into the bike I wondered if anyone else had experienced this or what the possible causes could be.

The bike seems fine under power and on the motorway its almost as it the tickover is too slow once the engine warms ups.

All ideas welcome.

Matt

strip out and clean the idle air valve in the airbox.

I think that your issue is identical with this:

Well after trying a few thing doing lots of reading on the internet. I took the decision to strip down the bike again. With the fairing off I went straight to the idle control valve and bingo looks like I hadn't connected it when re assembling the bike.

Thankyou for your advice I am happy to say bike now running fine with no issues.
