After reading about the 650 in earlier threads I would like to add some titbits that I picked up. The 1.75 journals were used in the 500 Dommyracer and in the aborted Unified twins before the SS or Manxman. I had understood there were only 2 Unified complete engines Built back in the day , AJD writes there were 6 bikes , Would like to know where she found that info. I am personally familiar with the two current reconstructions which run really well. I understood that the Lawton 650 was seized up by the works rider before delivery and had to have another barrel to replace the one with out of parralel bores . The Lawton bike was reported destroyed in the museum fire , but perhaps it just dissapeared !. I am Currently building a tribute SS producton racer so any information or photos of the Thruxton 650 bikes would be very helpfull.
