Hi all,
If we are on the subject of a company giving good service...
I have just had the valves done and the carbs balanced on my storm for €125 (about £110) by Checkpoint Motorrad Service http://www.checkpointborchen.de. Their customer service, advice and chat was first class (they also speak fluent English). If you are in the area (for whatever reason) they are the best in the area IMHO.
