DL1000, I have this annoying slow leak in my front tire. Everything was fine until that day I thought I'd make it over that small ravine. But didn't. The front rim got a bit bent, but the tire stayed inflated. I removed the rim assembly and took it to the local rim shop that does these repairs. It came back looking great. But has always had a slow leak from then on. No bubble leaks when submerged, at tire/ rim edge, valve or on the tire itself. It’s down about 3 - 5 lbs. a week. I’m starting to wonder if its leaking through a spoke up to the axle. I haven’t used a sealer yet, but I thinking about it.
