It costs lots of money..

I am on hold slightly at the minute as my garage roof is leaking and I am not going to leave an engine with no heads on lying about!!

Hi oily i now have nicks old bike, just wondering how long ago you did the work on the bike, ive currently got the engine out and doing the valve clearences which are way out so thinking maybe the valves need reseating. Would be helpfull to know exactly what work you did and how long ago, thanks

sorry to crash your thread royster :D
