Ready for registration.
I rechecked compression after the first ride and cylinder one had none.
A valve leak down test revealed the exhaust valve was not closing.
Pulling the head showed the valve bent.
Decided to take the heads and cylinders to professionals to get full makeover.
Bored out to 826, heads surfaced, valves ground, valve seats ground, helicoils, new valve stem seals.
Compression improved from 90psi to 150.
Headspec did the work, very nice guys and great work.
