[QUOTE="Graham Smith, post: 121769"] Short video clip of America's greatest Vincent drag racer running his "Barn Job" bike. It did 9 seconds and 150 mph on the quarter mile in the early '60s running on nitro probably straight from the can. This is the early version of Clem's 1700+cc Vincent, later it got a telescopic fork replacing his home-built one, and ultimately a supercharger. Here he was on 42mm Dellorto carburetors. This setup probably produced 300 horsepower from 100 cubic inches or so. One note about his whole history which covered many years, is that he finished with the same pair of original Vincent cylinder heads with which he started. Clem was a wizard machinist and welder and if anything happened, he fixed it like a traditional hot-rodder who doesn't want to waste money. With the blown fuel ultimate setup, he did have the head lifting on the cylinder and "torching". But he would just weld up and re-machine the damage, and keep right on. All this says something about the strength and integrity built into the original heads and crankcase of the 45 horsepower 1946 Vincent 1000cc Twin designed by Phil Vincent and Phil Irving.
