I traveled to my friend Jeff Wiley's on Saturday. I know Jeff worked and traveled with Leo Payne to drag races on many occasions. Jeff said the frame in this photo was one of the first Yetman frames. It flexed so bad that when they raced in Bowling Green, the chain came off and just spun on the brake drum. Jeff called it a piece of ____.(well, you know the word) Leo named it a "Flexi-Flyer" after the kid's sled. It just wasn't rigid enough to withstand the horsepower of this XLCH with nitro. Then Leo acquired one of the first Boris Murray frames and that wasn't much better. Boris then built another more rigid version that did hold up. Wiley has a memory like vault, you just have to open it up now and then to get the information.
