Priv, I need to have the hp potential of "hand polished seats" explained to me. I've been racing/modding cars and motorcycles for a long time, and that's a new one on me. In terms of valve "seats", I understand terms such as cutting muti-angles, lapping valves in by hand, etc, but "polished seats"? Your use of that term, in the context you use it, calls into question even a basic knowledge of cylinder head modification for me, as does your more general description of the heads as being "polished". Polishing is only one part of the process of making a better flowing head, and in some areas, can actually be detrimental. I realize that at this point, you can Google a ton of information on cylinder head work and reguritate it here, so I can only go by your original phrasing.
If Kawasaki was selling 200 MPH ZX-11's in the early 90's, and accomplished that feat of speed with no more than "hand polished" headwork and a $1,000 premium, it had to be front page news with the motorcycle rags. Such a factory offering would be akin to the COPO Camaros, for example, and it should be easy to back up a claim like that. It would be something of legend. I can only say that I had a ZX-11C, was very much into what was going on with those bikes and most anything that was fast at the time, and would be very impressed to find a feat like that passed my notice. I certainly don't claim to know it all, and I love to learn. Documentation of your claims, or, ANY verifiable, recorded precedent you can site of an otherwise stock ZX-11 going 200 mph with only "head-polishing" would be educational, to say the least.
Donny hit the nail on the head. HP must be increased exponentially to achieve such feats of speed as reaching 200 MPH. The unlimited Hayabusa of 1999 broke through the 190 mph mark due to, in as large a part as HP, wind-tunnel designed bodywork which made the ZX-11 seem a brick in comparison. That is evidenced by the fact that it was only a couple tenths quicker than the 11 in the 1/4 mile.
The rules of probability are stretched even farther by the conditions in which you describe your own experience. You were able to accomplish, on an urban freeway, what no one to my knowledge had accomplished at Bonnevile or similar facilities. I have a personal friend who has a turbo GSXR 1000, set up specifically for the purpose of breaking 200 mph at the Texas Mile. Pure race bike, not street legal. I can say without equivocation that his bike would make a ZX-11 with head work look like it's going backwards.
I find most, if not all of the rest of your comparisons of the 11 & 14 to be equally out of touch with reality. But let's retain focus on the 200 MPH bikes, as those other comparisons can be subjective. We'll stick with what you claim as fact. Facts can be verified.
I've read enough of your posts to know that you would demand no less of another forum member making similar claims, and, as such, will not take these questions personally. Your relation of Occams Razor to KHI evolving the ZX-14 is an interesting application of that theory. Applying the same theory to your claims, I arrive at the most logical and simple answer; it's pure fantasy. To remain within the bounds of what you feel appropriate on a personal level, I'll quote your response to RED in the "2010 Flies out" thread. "I don't believe you."
