RJ-
I was just poking around the various instructions listed on the Malossi website, they indicate that the piston ring gap should be no greater than 0.7-0.8mm or 0.027-0.031" ... 0.002" is microscopic(!) my feeler gauge only reads down to .006(!!) I can't find any info on dykes rings specifically, perhaps they operate differently than standard ring types (?)
