My friggin Gawd so It was only the tappet gasket, That is pathetic $300 for that you have to be kidding I replaced my tappet gasket when put the Chrome Rocker cover on and it took 1/2 an hour tops, He is Profiteering and ripping you off, and if it "is a recurring problem then it would have started recurring before you did your mods and one of the mating surfaces is faulty so they should either replace the head or rocker cover or both, but to be honest if he had put the gasket in properly last time it should have had gasket sealant near cam journal ends and the gasket is designed to fit quiet well so they must have botched it up or did they reuse the old gasket? last time
Don't let him get away with it tell him you are a Ulysses member and there would be a lot of triumph owners that would be interested in this capper, especillaly after he talked triumph into dis honouring the claim. Richard if this is not resolved I will Ring chris and tell him why I chose to travel further to Nowra for my dealer
