I just picked up a screw (about a #8) in my rear tire (Avon Venom X, MT90) of my Sportster. It caused a slow leak and I was able to fully plug it with a single plug strip. I never tried plugging a bike tire before, but this one only has 900 miles on it, so I would be inclined to try it. Anybody out there plug a bike tire? Is it safe to do? thanks, old dirtbeard
