Just like mine though mine was converted to 200cc.
When you pulled the starting handle the centre stand went up a lot of people disconnected this also the carb used to ice up in moderately cold weather so needed a new water heated manifold..one of the best handling bikes I have ever ridden.. use mine for commuting into London .. the engine now still doing Stirling service in a small boat.
Also known as the Noddy bike story says because riding the bike you couldnt salute to senior officers so alowed to nod...
