Nice videos. Honestly, I've never seen busted sleeves on one of these bikes. For this reason I'm going to shut up, watch and learn. While this... would be my next move I don't want to recommend unnecessary procedures. I'd also weigh the cost of a machine shop dropping a new sleeve in the existing block against buying a good used one. Looks like k-moe is for the latter. The other gurus (which I'm not) and members will hopefully chime in soon. Gary H.
