Hi thanks teecee I managed to get hold of a set that did the job, I have 5 on the exhaust valves that need adjusted.I am quite surprised as i thought this was the first check at 28k as i purchased the bike at supposedly 12000k 4 years ago, backed up by Mots and the bike was in very clean cond. When inspecting the valve cover there was grey gasket sealant in places between the valve cover and the rubber( (very amateurish looking application) which has raised my suspicions about this bike which is a shame because I thought i had a good un and have enjoyed every moment in the saddle on this machine and have had many comments on how nice the bike looked. ... Can you tell i'm a tad disappointed
