Eric Stevens Now there was a case of 1930's tech taken to its limits. The Vincent BL was an amazing machine, but even though it had that powerful motor, it was a 1930's bike (Vincent's 1936 Brough Superior beater) trying to survive into the fifties and it failed early. The frame, forks, and suspension were not a good match for the motor, and were obsolete in 1948. Undoubtably a work of art, but the record breaking bikes of the 1948 and early fifties were all custom frame bikes with custom forks. Not so. I worked with Bob Burns and Russel Wright on Russel's record breaking Vincent. It was standard forks and frame. The connecting rods were ex the Vincent Picador engine designed for drone aircraft, and were worth another 1000rpm. Both cylinders were fitted with ported rear cylinder heads which gave a better air flow. The gear box was the standard Vincent close-ratio box. The clutch may have been modified, but I can't remember.The fuel tank was a special. The oil tank was the main frame member as in the standard bike. OK! Not that I doubt you in anyway, but just which "record breaking Vincent" was that? ...and when was it you did this work? Not the Rollie Free 1948 bike, which was the well publicized record breaker. Certainly not the 1949/50 Reg Dearden bike which never actually made a run. Then there is the Joe Simpson Supercharged which held the American MC speed record twice. (that is currently at the Solvang Vintage Motorcycle Museum in California) ....and I hope I am not aging you too much, but just how old are you? They had to be. They are nostalgically desirable, and have great collector value today due to limited numbers, but even in the mid-'50's there were better bikes such as the 1955 Matchless G45. Maybe not as powerful but much better. Eric Stevens -- Regards, Savageduck |

When it came to coils and fuel pumps, especially in many Jags where there were two of those Lucas tickers, it was just a matter of sitting back and enduring the eccentricity, replacing as the need materialized. The only time a Lucas component has worked for me, was when the mechanical, cam driven fuel pump on my mother's FIAT 2300 failed, and I put a Lucas electrical fuel pump (meant for a Jag, and the only one available) in line, and it worked without fault for many years. It was just disconcerting to hear that ticking coming from a FIAT. -- Regards, Savageduck |

Several generations ago I was an engineering student at the University of Canterbury in Christchurch New Zealand.

I had my 500 Triumph up to 102 mph fairly early in the pice which was much faster than most of the other road bikes at the time (I eventually got to 118 mph, but that's another story).

They set a record of 186 mph on the Tram Road and later took the bike to Bonneville where they ran it at 198 mph. Unfortunately about two weeks previously NSU had taken the 'Flying Deckchair' to Bonneville and set a new record of (I think) 202 mph. Bob's explanation of why they didn't go faster is that they were just learning about Nitro fuel and didn't have the courage to tip the jug over far enough. http://www.jockeyjournal.com/forum/s...ad.php?t=73122 has a number of pictures of the bike as I remember it except that the rear suspension units have been replaced by solid struts. I don't know when that was done. The front brakes have also gone. Not the Rollie Free 1948 bike, which was the well publicized record breaker.

In 1967 he set the record for streamlined/alcohol 1000cc class, at 183.586 MPH with a one way run of 190.7 MPH. Not quite the machine movie goers saw Anthony Hopkins riding! Not the Rollie Free 1948 bike, which was the well publicized record breaker. Certainly not the 1949/50 Reg Dearden bike which never actually made a run.
