Jim Mosher from Santa Fe, New Mexico.

Hi John, I just got back from the Bonneville Salt Flats with (2) World Records. I wanted to again thank you for the pulleys, belts, and a clutch assembly that you sent me for this project. The belt system worked very well for me. I've noticed that the belts are slightly loose when cold, but as they warm up, the tension is just right. The belt system is a critical part of this bike, and I was discouraged until you came to my rescue. I wasn't able to find any belts, or pulleys that would work for me until you jumped in and saved me. Thanks again!

We did just (4) runs, and set (2) records. The track was wet, and raining part of the time. Plus, I had some troubles each run that I had to deal with. My magnetos were destroying my "Black Box" air-fuel data, so I had to guess at the proper jetting. I just went way rich to save the motors. We still increased the record by 20 mph! Our best run was 153.3 mph. I know the bike will run in the 160's when I get a few minor details changed. We will be back next year for Speed Week, and I'll keep you posted.
