Re: Peanut silencer

This muffler dates back to about 1965-1966. It is constructed of Unobtanium and is now quite valuable. If you rechrome it and fix the significant boo-boo's, it will be worth even more. Consider this to be your retirement fund. Don't tell the taxing authorities you have it.

Re: Anti-wet sumping valve

When you say, "Suck", does this mean like we did when we were 18 years old to syphon some gas from Daddies car to run our BSA's on a Saturday night?

Oh!, for the nights when our girlfriends would loudly complain about our 100 octane breath.

No, my friend, Cocker Cox. The ring gaps were set in a line by the boys on the engine line at BSA during the initial assembly. Had I taken it back to the dealer prior to the 6000 mile and/or 6 month period, repairs would have been for free under warranty. Or, so I like to fantasize.
