If anyone out there is looking to have their barrel repaired, try Langcourt at Weston-Super-Mare(advertises in Trials & Mx news). I had a cracked barrel which had been botched by a previous owner, I sent the barrel down to Langcourt (I live in the north east of Scotland) and received it back 2 days later. The standard of the repair is excellent (I thought it was a new one!) and the engine now no longer consumes 9 gallons of water everytime I start it up, the cost?
