1954 BSA B33 chassis with a 51 ZB33A engine. Has a thor spark installed. Starts on first kick. Runs a shifts fine. It will need the top end done soon. It is burning some smoke. Could be valve guides. It's ready to be made into a goldstar replica. I got it from canada. I have import paper work that can come with the bike. I haven't taken it to a field office for road worthy inspection (being foreign import), which I think is a crock considering its age. I was just going to apply for lost title here In florida but since I'm selling it I will leave it up you. I will supply a bill of sale.
