Hi Andy,
I had my 14500 service done at Avsco in Watford. I was going to do myself but you need a computer to synch throttle bodies. They will give you a spare bike if available I forgot to book it but they gave it anyway.
Bike was running rough before service (March 2014) and done 4000 miles since very pleased with service.

Spare bike is an old Honda rough but does the job.
Hope this helps
