You *can* supercharge petrol engines too. That wouldn't address the durability concerns completely, though. That is the main caveat of normal two strokes. Sarich manages to address a lot of the disadvantages of two-strokes, and gets better performance than four strokes in nearly every category...
You want to try a Viscous coupling, as used in 4WD Vehicle transmissions. They can be built to have varying torque characteristics against rotational speed, even to the point of locking-up completely. with the right set-up it is possible to have negligible torque at very low rotation, rising at...
You won't get much more data from a manufacturer, because they don't usually have more than is published.<br>

Just jack up the wheel and lay a piece of square ruled paper under it and let it back down onto the paper. When you've jacked it back up and got the paper out, you can count the...
Well, that's a hard one.. It's not so easy to calculate deflection over load. Usually the tyres are specified for a particular pressure for a particular load, up to a max. pressure for a max. load. This gives the same rolling radius for the tyre. By nature deflection is not linear against load...
