I’d be checking ,
Valve clearances ,if excessive .why
Camchain blades,
if the above ok make a decision how far to go
As then the heads and barrels will be coming off.
I'll have another look tommorow or thursday weather & time depending
I didnt whip the LHS off as the crash bar is bent a bit and its a pig to get the cover off / on lol.
Valve clearances were felt not measured, i'll do that next time -
couldnt see any obviously loose lock nuts but i'll check again -
Camchain blades - not sure how to check but what i saw- the lower one looked ok - (says he who hasnt got a clue lol)
If its heads and barrells off, then its beyond my level ...
