Yes 1975 Calgary. Whaley was to young to ride but was at the event with the Honda team. Most likely Mark Eggar Somewhere I have the program and the results. Guess you had to be there!
I agree with Steve. But at the same time all 2 strokes need to be jetted to the fuel and oil mixture used. I use OPTI-2 in my sherpa @ 50:1 with excellent results. Optimol is a good choice for all 2 strokes. Also I use a gear oil compatible with wet clutches in the primary drive and gear box.
