I think the petrol issue might have been worsened by the journey here on the back of a recovery truck Doug - bike upright, bouncing around for 150 miles, fuel in the tank and leaking through the carbs.
The engine only had a few seconds of running once we'd gotten it off the truck, the exhaust smoke was enough for me to shut it off almost straight away, so I doubt "wear" will be an issue - but I'm surprised too that there wasn't a hydraulic lock and bent rod.
After the bike was standing overnight, no more petrol had leaked through into the sump (hence me thinking the journey might have helped with the flow) but I'll be refurbishing the tap regardless.
So far I think we have been lucky with damage, but its a whole top end removal job (at least) to check everything out and sort it. Looks like I might be busy
