As you can see its a job lot. The frame hanging on the wall has been professionally modified to lower the engine and it has surface rust only. The spare engines are all reed valve but the engine in the bike is pre reed valve. I've had the bike since around 2004 its spent most of that time locked up in a shed. When I purchased the bike, I was told it was built by a 2 stroke specialist back in the 70s called Jimmy Smithurst. He had a engineering company in Taren point NSW
