Time was flying by, wasn't it Ken. Can't believe is was over 3 or 4yrs that we last spoke.

I got the p/n thanks.

You're implying you took the the outer cover off: I don't even wanna do that! Oh, and apologies for not properly re-introducing myself: I have been in hiding after the planned Alaska trip with a friend fell through in 2011. Took me a while to deal with it. Started that RS conversion project in 2012 ...

Given the shape of the seals, either 82mm or 84mm on the /7 should seal just fine. Not sure why the /6 cylinder measure longer when all Airhead engines have the same stroke.

But it would seem that as long as the tube is positioned far "enough" into the head, the more critical dimension is what I was describing. In other words, you want the stop ring to be the right distance from the block so it puts the proper squeeze on the seals. Yes. And that is exactly my...
