Bloody hell, what a situation to be in… having traveled on my old AT I know how attached you can become…
Looking at the problems, a replacement engine would be the way to go, but of course you never know their condition… you might find an enthusiast breaking one, so look on ebay.co.uk and the xrv website..
What bad luck, I’m surprised you didn’t hear anything as your valves destroyed themselves on the piston crown.. thinking out aloud it couldn’t be the cam timing – would the bike run with it out so much ? if it’s the valves, adjusted hot or cold they would only contact if you’re flat out say 7000+ rpm … so are the replacement pistons too long in the body ? might explain it or the valves the wrong length … no mention of different con-rods and again if the crank and big ends are shot still wouldn’t explain the damage. … broken ring… naa
Good luck mate, take some time off from the bike and go back to it with a fresh head….
looking again at the enlarged pix, the bloody valve is broken.... OK forget the rest of this message......
