HammerShee99 Posted September 4, 2007 Report Posted September 4, 2007 I was riding over the weekend and got plenty of good riding time in, but that all ended when the right-side O ring on the head let go and it let antifreeze into the cylinder... I pulled the head off and got all the antifreeze out of the cylinder and tried to kick it over, it turned over a bit the first time I kicked it but after that it was completely locked. The left-hand cylinder is fine but the right-hand piston is pitted, and it's pitted around the dome in the same pattern, so obviously the piston was coming up and slapping against the dome. I'm sure that at the very least the crankshaft's hosed, but not positive. What do you guys think, and if the crankshaft is fucked, would I be better off trying to rebuild the engine I have (4mm stroker, just dumped a bunch of money into the top-end) or scrapping it and getting a new motor?

dajogejr Posted September 4, 2007 Report Posted September 4, 2007 Pull it apart...see what the carnage is... I'd bet a rod is starting to go....since it tried to hydrolock itself. Did you get all the coolant out of the crankcase, too...or just the cylinder? Quote

dajogejr Posted September 4, 2007 Report Posted September 4, 2007 I haven't gotten a chance to get into the crankcase yet, just the cylinders. I know...I'm just saying you're gonna have to. I can promise rebuilding what you have is cheaper than all new parts.... I wouldn't scrap it. Probably looking at a rebuilt crank, new or re-machined head, pistons and new bearings, gaskets and seals... If the bores aren't fubared.... Still cheaper than a whole new motor. Quote
