burnt dry piston head?

[Godric]

Hey guys, been a while since I've been in the garage on account of me breaking my arm pretty bad, but I'm back at it now more than ever. Last time I rode the old man he started blowing smoke real bad on the right side and wouldn't stay on. Maybe lost compression? Anyway I said f**k it I'm gonna use this opportunity to tear it down. I started the teardown a few months ago and failed to notice until today that the likely culprit of it not starting was a blown fuse. Well I tore it down and found that the right cylinder head was totally dry and covered in carbon and gunk. No scoring of the cylinders or pistons, or rings for that matter. Also rods are rusted? Any advice helps ladies n gents thank you

Maybe one of the carbs isn’t flowing fuel to the cylinder. The blown fuse wouldn’t have much to do with it, because the ignition coil fires both sides at the same time.
