I bought this video because I want to understand clutching, I also want to start trying to play with clutching but I'm a complete newb. My only knowledge comes from forums such as this, I don't have any riding buddies that do anything but gas and go. So with that in mind after watching this video I give it a solid "C". It's a little older, all the clutching is based on Polaris, and the price was high ($40 shipped to my door). It gave a great basic clutch tutorial, but did not really get into any serious clutching theories. I guess it goes over everything a person needs as far as cleaning and minor tuning, enough for the average rider. If anyone is interested I'm selling it, $20+ shipping or B/O.
