I spent all of yesterday in the workshop with John from CMW. He went through a major service with me incl valve check, changed just about every consumable inc new chain and sprockets. He also fitted new LED bulbs I bought from Amazon (wow - the lights now), plus my K&N filter, power socket and new Hyperpro fork springs.
It seems John has spent his working life there and knows his stuff. They also sell Royal Enfield, April, and Moto Guzzi so if you fancy a service and a different kind of bike to ride give them a call. Goodwood is not far away and their cafe is open for a brew and cake.
