Well, my mechanic-ing skills (or lack thereof) have once again cost me some downtime and money. I forgot to put oil in the damn thing and siezed the piston following a head gasket replacement. I was looking for the least expensive repair method and so far Eric Gorr big bore kit is slightly cheaper than stock part replacement. I researched the big bore topic on this board and the posts are sorta old when reliability data was suspect. I was wondering a few years later if the 444 big bore kit was reliable or not (assuming you put oil in). I went two years on my bike before the head gasket failed. The cylinder showed little to no wear when I originally had it apart for that repair. Based on that inspection I was hoping to get 4-5 years out of the stock cylinder/piston combo (I don't ride a whole lot). Any reported premature failures of parts due to big bore kits?
