T.C. Christenson's "Hogslayer" twin-engine World Champion Norton Drag Bike..Running

This is a video I took at the INOA Norton National Rally in Havana, Il. on July 31, 1993 of the famous "Hogslayer" Norton Drag Bike owned and operated here by the one and only T.C. Christenson of Sunset Motors in Kenosha, Wisconsin.
With the 300-plus horsepower in the 1,620cc nitro-burning Hogslayer, Christenson ultimately ran in the mid-7s at 180 mph and for most of the early-to-mid-1970s he was the fastest drag racer on the planet. In 1972, he won the NHRA U.S. Nationals in the first year Fuel Bikes were part of the program. In 1973, he lost only once and set the A/Fuel Bike elapsed time record with a 7.83-second run en route to his Top Fuel win at the NHRA National Motorcycle Record Championships in Bowling Green, Kentucky. He set numerous world records and was featured in motorcycle magazines. Christenson won the official NHRA Fuel Bike National Championship in Indianapolis in 1976.
On a side note, If you look closely at the end of his burn-out you can see small parts dropping to the cement pad from the area of the rear axle.
