Hi. I'm Derek, from Derek's World of Motorcycling. Enjoyed your video! 😊
I was using the same telescopic gauge set as you, but decided to invest in a bore gauge tool for better accuracy.
Fractions of a millimetre can make a big difference w.r.t. piston clearances - as I've found out! 😮

Crumbs! That’s bad luck. I hope you manage to get a new piston or a decent cylinder (and in time for the event). My Innova is nowhere near ready so I certainly won’t be there! Les in Chester

It's in the post, so its fingers crossed it arrives and I can rebuild it in time !

[@leslieaustin151]

@@justanothermotorcyclist nail-biting time then! Les

I have a new 1mm oversize piston & rings kit if it is wanted? Ah, never mind. I just saw the post below!
