Idle surging?

I'm looking at a k1200 that has surging idle. Is this the airbox valve problem?

There are probably several causes for idle surging on the K12. On mine, a 2008 K1200GT it was the airbox that was causing a high idle when engine was hot. The throttle would hang up in a high idle, making for some interesting situations when trying to stop the bike at a light. A newer, updated airbox corrected that problem.

You will have to determine that all other maintenance items have been addressed before anyone can assist you with troubleshooting your idle surge.

To start with, what year and model, mileage, service history and status are you dealing with?
