I never actually bought any of his videos, I just like to catch his shows at IRL events. While I've heard the gyroscope flywheels theory repeatedly - usually from guys that like to slow race at 5k+ - I never believed it (I stay around 1,200). I think it's just a matter of using the light torque pressure on the driveline to keep weight off the front wheel. The eyes thing really is the most important part allowing the rider to keep their balance - focus too close and you start to wiggle..
The gyroscope thing is something I thought up on my own. I never asked anyone about it and you're the first one I've heard mention it. Like you, I keep the RPMs down. On the 103 I was able to run it between 1200 and 1500. With this M8, I finding I have to go 1500 to 2000. You don't need a high rate of revolutions for the gyroscope to work. When I was a kid, I'd take the front wheel off my bicycle, hold it by the axle, and spin it by hand. Once it was spinning, it was tough to change the plane that it rotated in. You'd actually have to twist the axle against the rotation to get the wheel to move.
I never thought about getting the weight off the front wheel, but that does make sense. I've found that if I can understand the physics behind something, then I can concentrate on what I need to do, so I get the desired result; other wise its just hit or miss until I stumble upon the answer.
The last time I was able to practice with the folks I mentioned before, they had me riding snowmen. A series of circles, each having a smaller diameter. I'd enter the first circle, ride around it and exit it into the next circle. Once I reached the final circle, I'd reverse and go back through that which I just came out of. In each circle, you'd reverse the direction around it from the previous circle.
I watched them play a game called "last man standing". A series of cones were set up. Two guys would ride the cones, playing follow the leader. The 2nd guy would need to make the same maneuvers as the first, while the first guy would try and position himself such that the 2nd guy could not follow. At the same time, the 2nd guy was trying to prevent the first guy moving forward, to establish another maneuver. The first one to put a foot down lost. Sometimes these guys came head to head, stopped. They are able to keep the bike upright without it moving.
I'm told that the forces of the drivetrain are balancing and counteracting gravity, so the end result is that nothing moves. So far, I've only been able to stay stopped for about a second. I had thought I might be able to win a slow race, until I saw this. I can't go slower than stopped yet.
