Yesterday evening I was reading an old article about the 'Worlds Longest Road Test' ( I know sad innit) this was Tony Rose's effort to do 100,000 miles before a de-coke, which he succeeded in doing back in the 50's, this is well documented and has passed into legend for the Vincent Marque. However, according to the text he was in Scotland and at just over 50,000 miles was about to return home when QUOTE: "we diagnosed an engine fault, a weak valve spring. Immediate panic ensued! Was the test all over? Would the motor have to be stripped?. Second thoughts are often the best, and when we had cooled down a little and taken time out to think, we realised that due to the unique Vincent method of locating the rocker below the valve, it would be possible to alter things without disturbing the carbon ( an essential prerequisite for the test). As Tony's holiday was almost over we decided to leave well enough alone. I later heard that an inner valve spring had fractured, but that this had been successfully replaced by the method we had worked out. The carbon had not been touched, nor yet the valves ground in or anything else to the motor. So the test continued".........................................................................................
How did he replace the valve spring????
