This bike out runs 500's on th flat... and annihalates them on the hills.
1947 with 48 engine. Heavily ported by a previous owner. I had to fit a larger ( Harley) exhaust valve to remedy an over ported exhaust port.
1 1/16" monobloc.
Engine fully rebuilt... and balanced. Balance factor slightly altered to better suit high speed running.
Standard early HEAVY flywheels. The secret of reliability at high revs
