Love those copper gaskets
« on: April 27, 2018, 07:38:23 PM »
Just recently I had the heads and barrels off my LM1 to deal with oil blowing past the rings. At the same time the heads were refreshed with new guides, a valve regrind etc. I reassembled with copper gaskets and I am very pleased with their stability as  after 3 torque checks/retorque, the valve adjustment specs are super stable. I have used copper gaskets before on my brit bikes with good results so I am not entirely surprised. The site I got them from is : http://www.coppergaskets.us/ if anyone is interested. The gaskets they show so far are for roundfins, but the site states they would make gaskets upon request. I got mine from their Ebay store. No affiliation, just passing info to fellow guzzisti

Why did the manufacturers get away from the Copper head gaskets?

Just a guess, but copper is expensive. <shrug>

What thickness head and base gaskets did you use? They have quite a selection of thicknesses. I like the fact that they are re usable. Some times I have wanted to pull a head for this or that reason, and have hesitated due to the gaskets not being re usable.

The ones I used are .042. Round fins ( 89mm) and square (92.7mm) are offered. The round fin 83 mm is not  offered or the smaller  square fin type ,but , with a sample they should easily be made up as well as other thickness  sizes. They are in Phoenix so turnaround  should be fairly quick (?)
