Bean Oil. Yea, I agree with Patman on this one. I remember the great smell associated with the bean oil. I race super vintage bikes in hare scrambles and don't have either the time or the parts availibality to be breaking down the motor on a regular basis. In other words, I like the smell, but not the procedures to run it until they come up with some kinds of improvements. Until then, all the riders behind me will only continue to see the dust settle as I ride ahead.
