Berkshire Spark Arrestor for Carl Cranke Mod

[johnbowman]

Hello Poggers! I hope everyone is staying safe.

I'm building two Berkshires for the 100cc class next year in AHRMA. I got a bike from Larry that has the Carl Cranke mod on the exhaust. It has a J&R Krizman 812 spark arrestor welded to the stinger. The stinger diameter is right under 1" (26mm). I got the bike together and man it runs great! I really would like to get another spark arrestor similar to the Krizman. I've searched the old interweb for hours with no luck.

Does anyone know of a good repackable spark arrestor that's available to day to use for the Carl Cranke mod?

Thanks,

John
