J.A.P. Engine – Inlet & Exhaust Valves

A pair of unused valves, as used on 1930s race JAP engines.

The exhaust was made by G&S Valves, a great company and happy to do small numbers.

The inlet has a lovely pronounced tulip shape but cannot recall it’s source.

Overall length 4.2” & 4.25”, head diameter 1.6” inlet , 1.65” exhaust, stems 11/32"

New and unused.

Both valve pairs have done active service in my Excelsior JAP without issue.

Also suitable for Royal Enfield Ariel, J.A.P, Excelsior , Brough Superior, Harley Davidson, Indian, James, Levis, New Imperial O.K. Supreme, Panther, Rudge, Sunbeam, Triumph, Vincent HRD ScottSidecar
