Just a passing thought!

Find other ways to add more flex.....

I agree. Although I wouldn't call others who disagree stupid.
I used to race motorcycles and it was interesting watching the likes of Honda and Zooky play around with chassis flex in order to get the much smaller than a car's tire rear contact patch to put the power to the ground. They ended up with two problems. 1) Chassis flex and its effect on handling is mildly unpredictable at best for all types of situations that occur within a race. 2) Insurance rates for the average rider increased with the huge increase of total lossed claims due to bent chassis'. They also ended up with one solution. Stick with a predictable, rigid & very stable chassis like the green machines had. No wonder EBoz spanked em at first so bad with the 750 when they had all moved up to "flexin" 1000's.
I'm a firm believer that if you've tuned any vehicles suspension correctly, with a rigid chassis, it will be more predictable and consistently faster in a race. But it normally takes a good deal more time to dial in the setup and any tiny deviations from such setup are very uncomfortably noticeable.

John Q , if only one screw is stripped out, take off the top deck from the front bulkheads...and push againt the stripped screw with a finger while you wiggle the bulheads back and forth...hope this helps-Steve

I have drilled off the heads and made it work. After you drill them off and remove the bulkhead, if you don't use to big of a drill bit, there should be a small portion of the screw sticking out. Cut a slot in it with a dremel tool, heat the bulkhead, and presto.... the screw will come out easy with a small screwdriver. I have used this method a couple of times, worked every time. Just be careful not to drill to deep or the screw won't be sticking out of the bulk, then you get a slot in the bulk to with the dremel.
