Just a couple of thoughts, I would never consider top end repair or replacement without resealing the bottom end. The top end is what fails if there is a fault in the bottom end. I also don't see any chamfer on the ports, something that must be done after the cylinders are bored. I have seen many failures because of improper port chamfering. Measure all of the clearences carefully after the machining, personally I remove the cylinders after the breakin procedure and recheck all clearences, polishing any high spots that show up on the pistons. A little extra effort will ensure a long life engine.

Hi All l removed the barrels and check them when l did the carby rebuild no marks or scuffs at 21.5 hrs
The motor had new seal with the crank replacement.
