HI TO ALL, I THINK I FIGURED POSTING OUT!! I JUST MADE 2 OTHERS BUT THINK THEY ARE BURIED.. I DON`T SEE MUCH POSTED ABOUT FRICTION DRIVES. I BOUGHT MY FIRST CYCLE IN 1955, 1936 HARLEY 80 CUBIC IN. FLATHEAD. I WASN`T AWARE HOW FAR THE MOTOR BIKES HAVE CAME UNTIL THE FIRST OF THIS MONTH. I ENJOY THE FORUM. VERY HELPFUL !! LATER GUYS, RON
