[QUOTE="b'knighted, post: 22758, member: 59"] Go Wild, Sorry to criticise but you really mustn't think of the Comet as only half a Vincent. As you are a beginner it may not be obvious that the Comet is so much more but, although it is only 499cc, instead of 998cc, its performance is considerably greater than half the performance of a twin. It is only missing one cylinder and head, its still got all the other good points. Notably, when you get it sorted, it should be able to approach 85mph in third, one or two up. Mine did that regularly but never exceeded that in top, which I'm sure relates to the overgearing. Not many twins can boast double that speed. It should return better fuel consumption figures than a twin and will stop considerably better. It will be easier to throw about on winding roads and in traffic. In case no one has pointed out to you it is closer to Black Shadow spec than Rapide and although it uses a front head it has a rear cam.. If the postwar twin did not exist the Comet would shine in comparison with its contemporary 500cc competition. The good points of Comets only get overlooked because on the twin they are so famous.. Good luck with it and when the time comes try to add a twin to your stable rather than replacing the Comet with one. They go well together. Cheers, [/QUOTE]

The Series 'A' Rapide was known as the '********' Nightmare?
