it wasnt a death rev for the Z. Just running on a nitro methane mix called Witches Brew. Uncle Kipp mixed it too hot that night, whooped the EFF out of these out of town punks, and then couldnt kill the bike because of how hot the fuel was burning. Uncle Chey had to put it in 4th and drop the clutch twice while standing on the rear brakes to make it stall out.
Uncle Kipp has pictures of it coming off the line that night with all 3 tires in the air and a 6 inch flame coming out the stinger of the pipe. Waiting on him to find them...
