You can do all the equations you want ... who do you think is fgoing to make it for you ...
There was one guy on gs500 who was designing a shock. Finally only penske would take it and make that in theory, for a 2500 per item charge. They also revealed that their regular shock is not that far from his design that he could have for $899.
In a way you have to fit it and ride it and see. design and computer aided bs is worthless unless you have someone who can say, Oh you have a computer aided design there, bring it over and plug it in and make it and hand it to you.

Engineers throw semi caliberated things together and see how it works. Scientists try to caliberate and calculate everything till its fine down to the last decimal point. Then its so complicated no one can understand it, let alone make it.
To an engineer, 12.5346547 is 12.5 ... Easy crap is all I did ... didn't do no calculation of trail or nothign without making it ... made it marked the ground and measured it.
Anyway the thing is ridiculously bouncy cos the wheel is really really out of round and out of plane. Its like a C and has a non centered hub.
The disc is also like a wedge instead of being flat all the way across. That make my ride near impossible on sunday. But the run through the street was enough to tell me, the wheel wants to flop over at low speeds. The next step was to check trail.
Sure enough it was negative by about 2 inches. I then flipped the legs side to side and front to back, so I now run the disk on the right and the caliper leading the forks and the axle trailing.
The next step is to finish the job and run the bugger. The bad disk and the bad wheel not withstanding, if this is better than before, I run it this way. I get the wheel laced right and the tire fitted the right way and get a new disk made. If it works, I'd say I have a decent setup for a chopper and make a couple more for my other bike and this one - this prototype has some defects in it ...
Maybe I can sell it, but it does involve some work on the buyers end. Need to pull your stem and fit into this one, source a 14mm axle bolt (junkyards are good for this I found a dozen and I hardly looked 2 mins). Anyway we'll know in a bit.
Cool.
Srinath.
