Fogcity Posted September 30, 2021 Report Share Posted September 30, 2021 (edited) New to me Bultaco. I just registered it with a Bill of Sale (title was lost) and now I’m ready to buy some parts for it. I was under the impression it was a ‘73 Pursang 250 so I was looking up the model number and found that my frame I believe coincides with a 125cc model. The PO did the restore on it (replaced seals and gaskets and the ring, didn’t replace piston) and clearly knew what he was doing so I’m assuming the engine had been swapped for a 250 at some point, but how can I tell? Any help would be appreciated. Number on frame: B-10000131 Number on engine: M-68018557 bultaco.pdf Edited September 30, 2021 by Fogcity Quote Link to comment Share on other sites More sharing options...
