1928 Sunbeam Model 6 Longstroke up and running

It was great to get an email from Tony Petherick to say that the new forged piston we supplied was working well in his 1928 Longstroke Model 6. It’s lovely to see one of the iconic Sunbeam models retaining its valanced guards and running with leg shields too. In addition to its lighting kit, the bike also features footboards and an enclosed rear chaincase that hasn’t been lost like so many others.

Tony has fitted more sporting cams to the bike and reports that it runs very well after advancing the inlet cam by two teeth from the marked position. Does anyone have any ideas on cam timing using different cams on these bikes? It was a common “dodge” to fit the 60:30 OHV cams to the sidevalve bikes..

If anyone has a spare petrol cap for the bike please get in touch as the one fitted isn’t quite right and Tony would be keen to give a genuine Sunbeam item a new home.
