Yeah, that's your engine. It ripped all winter long on the ice. My son only lost two races. One he ran out of gas (his fault) and the other, he lost to a bbk raptor (he had beat that machine before, but it just wasn't his day). He dominated the 450s all winter and even finished ahead of most of the outlaw riders when they combined classes.
the piston skirt failed, no big deal. Everything else looks good. 72.5 makes sense, that 72 + 20/1000, right? The batteries are dead on my caliper, so i probably didn't get the most accurate reading. Is that a vito's piston? I can call them, they should know.
Great engine, I'm glad we made the deal!
