Before I buy that 'excuse' I want to see the ORIGINAL configuration flown unmanned.
If it prematurely deploys the chute, no leever-yankin' could take place unmanned.

You're right that we can't know for sure unless they tested a mockup of the chute release after the jump. More guts than brains, yes. He was a smart guy when it came to publicity, but a dolt when it came to doing stupid crap like blowing all his money and going deep into debt, assaulting women, etc. However, he knew that HD would pay him a crap load of money if he jumped their bikes. He knew he could easily obtain a bike that would make his jumps seem easy and people would quit paying attention. When he moved to the HD XR750 dirt tracker in 1970, he claimed it was for the strength of the frame and the power of the engine. He could have built a custom frame with longer travel motocross suspension and a honkin two stroke for light weight power. The crashes probably weren't intentional, but he knew that without them, people wouldn't waste a nickel to watch him anymore. Why do people watch NASCAR? They don't go to see cars turn left 800 times in a 500 mile race. They watch to see them crash...and their guy occasionally win.

I don't think Evel chickened out. Robert Truax's hypothesis about the parachute cover may have been correct, but Evel could still have triggered the 'chute too soon *without* having panicked. If memory serves, the Skycycle's parachute system was deployed by a "dead-man switch" (just in case he experienced a black-out [or maybe a red-out, had the Skycycle spun rapidly--if, say, a fin had failed], as Truax left nothing to chance). It's possible that the acceleration--even if "on spec"--was greater than what Evel was expecting (mentally anticipating), and if his hand slipped, or if he momentarily relaxed it to re-brace himself against the acceleration, that's all it would have taken, and had he made such a basic mistake, he could easily have been too embarrassed to admit it afterward.

Attempting ANY of the stunts he did on any sort of bike produced by Hardly-Movingson (heavy, slow, no useful amount of suspension, infinite other problems) was totally MORONIC.

Yep. Unless it was a custom frame with a Harley engine that wasn't a Harley. HD had to start using Rotax engines in their dirt track bikes to remain competitive. I can't remember when it started, but I know they were using Rotax in the mid 80's and calling them HD. The AMA eventually changed all the rules to cheat for HD just like the NHRA did for drag racing so the HD style motors could became competitive again. Same crap happened in AMA and World Superbike road racing to make Ducati and HD/Buell competitive, but only Ducati was successful with rules allowing much lower minimum weight and much greater displacement.

LOL, I reckon so. Their race bikes aren't very fast unless someone else built the engines. There is just so much you can expect from a potato-potato-potato noise maker. It accelerates from zero to "I'm gonna blow that thing up if he keeps revving that @&*$ thing in the driveway" in less than 10 seconds. HD may have welded up the combustion chamber and assembled the parts of what looks like an extremely simple liquid fuel engine, but they sure as heck didn't design it!

"Before AMF bought Harley-Davidson, they had a contract with the US Navy building rocket engines. Production of these engines continued after their acquisition of Harley, being built alongside the motorcycles that came out of the York, PA plant. The model LR-64 was used in the AQM-37A "Jayhawk", a supersonic target drone missile, which was produced by the Beechcraft Corporation. These were used by the US military to simulate different kinds of missile attacks. Some of the models were even fitted with a two-stage parachute so they could be recovered." (The ablative-coated AQM-37A/D [see: http://www.designation-systems.net/dusrm/m-37.html - Rocketarium's scale kit depicts the AQM-37C] can even reach 100 km [62.1 miles] altitude, a range of 425 km [265 miles], and a terminal velocity of Mach 5, when flown in a ballistic missile simulation flight profile.)

I just came across *this* www.youtube.com/watch?v=yJoxVnmCF8g Harley-Davidson film from 1985, when they were static firing a single-chamber, variable-thrust AQM-37 rocket engine (the operational AQM-37 versions use--and have used--a two-chamber LR64 engine, consisting of a booster chamber and a sustainer chamber (the larger booster chamber shuts down after the vehicle reaches its desired cruise speed, which is maintained by the smaller sustainer chamber), and:
Here (see: www.youtube.com/results?search_query=aqm-37d ) are AQM-37 (mostly AQM-37D) target flight videos.
