Im 52 had bikes my whole life and always done my own spannering , so I won't be so much learning how to split engine cases as I will be learning how much beta parts are !!
Anyhow good news is piston and barrel are like new , no play on the Conrod , slight play on the needle bearings/gudgeon pin.
Couldn't split the cases as I was unable to find my magneto puller or my 2 leg puller , so have to wait a few days .
Oh and the water pump seal was like a piece of stone , not much sealing happening . So at least thats a obvious pathway the water used ..
Thanks for any advice , I'll post some more photos when I get the gear shafts out , don't think it's gonna be pretty
