Sooner than you think, my recommendation is either Gowanloch or Flywheels.
BigIan, interesting story and one day I would be interested in the Frasers story.
For me, I have had Rob from Flywheels do all the work on my bike I don't do myself. As with Big, I use 5100 Motul (on Rob's advice and for the same reasons listed by BigIan) and change the oil every 3-4k.
The only other person to work on my bike has been George from Frasers - good news that he is now at Flywheels
