Thanks Bruce,
I would love a pair of the aluminum style washers. I will disassemble
one of the brass petcocks and compare the two washers, and take a
digital pic. with dimensions.
Where do I send my contributions to the Guiness fund?

| Fred, I've made these from a sheet of Viton (1/8" thick, I think) and used hole (hollow) punches (3/4" and 7/32") to make the appropriate holes in the right locations using an old gasket as a template. Mine have been in my bike over a year with no leaks. My petcocks are the aluminum sugar cubes. re: leaking rear main seal. Now I believe, after taking everything apart, that my rear main seal was never leaking at all. All the oil that was dripping out of the clutch drain slot was coming from the hose that connects the crankcase to the air breather box. The OD of the tube is 18 mm (.70") and the connecting hose is 3/4" (.75") and my hose clamps apparently did not seal all that well even though they were snugged down tight. Visited about 5 auto parts hoses along with foreign car dealers looking for some oil-resistant (basically fuel line) 18 mm fuel line with sad results. My current idea is to wrap plumbers Teflon tape around both tubes to take up the extra .05" to prevent any more leaking. But it was fun popping off the rear main bearing carrier with my never used harmonic puller. It was much harder getting the seal out of the carrier! |
diameter. Before you button is all up make sure the leak isn't at the
rear cam bearing plug. I am working on a LM1 for a guy and it has a
leak there (or it did, before I JB welded it!).
