I've used these guys ( Adis Motorcycles Home ) for a good few years now, and they always do a great job. They have just carried out the 15K service on my 1200 Mutley with no probs at all. Adi has a laptop and correct connections so can reset the service reminder. He has done Testastretta engines before, but mine was the first Mutley. He reckons the next one will cost just under £500 - this includes VAT !! Highly recommended
