Bruce,
Mine are the chromed brass type. I ended up making my own using some sheet
rubber or synthetic material lying around, so I don't know what kind it is,
and a leather hole punch I got from Sears. Works so far, a couple of
months.

Mine have been in my bike over a year with no leaks. My petcocks are the aluminum sugar cubes. I do have another used gasket that is different (Rich P., are they from a chromed brass unit?) - different thickness and location of the two holes. Looks more like the dreaded 'smiley face'. Tomorrow I'm off to the same supplier of my Viton to see if they have some thinner Viton so that I can make some of these. I can take a digital picture of both gaskets and sent them to you and you can see if they are like yours. I've got a bunch of spare aluminum-style gaskets for $.50 each. If I find some thinner Viton, the chromed-style will be the same. I'm trying to make enough for a one-way ticket to Dublin for some fresh Guinness. 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! Bruce '72 Eldo Fred Sahms wrote:
