Anyone ever have an engine case crack whether the swingarm pivot passes through? I just noticed a crack on the top on the engine on my 05 EC250. No leaks when sitting, but weeps when ridden. Dang, how the hell did that happen? Bearings are fairly new, and pivot is correctly torqued. Found the crack when showing the bike today - it was up for sale. At least I caught it before the buyer handed over the money.
