As per the title I am after recommendations for someone in the UK to carry out a refresh on my race bike engine.

It's an nc30 motor, in a 35 frame, ideally they would be Midlands based.

Mike at bmc Whitchurch he is the man for these bikes

You could also try Graeme France of GF Racing, based in Brigg, Lincolnshire. He's worked on two of my bikes and he knows what he's doing.
