Figures don't lie, but liars figure. Did you even read my original post and what my goals are? Additional preload alone may accomplish my goals of holding the bike up under it's own weight. And yes, I am familiar with progressive and dual rate springs and understand the impact of modifying them. I have done it before. But by your response, it does not appear that you have actually shortened fork springs. Have you? Your facts and figures do not take into account what happens in real life. Whether because of the loss of preload or because of the impact on rate, I can tell you from experience that shortening fork springs DOES NOT lift or stiffen the front end. You can site all the theory or quote all the books you want, but if you haven't tried it, don't preach book specs.
And Oyabun, I said nothing about spring rates when I mentioned the possibility of shortening the springs if necessary. I said it may soften the front end. As before, I think you have confused two different things with your book specs. You are hung up on spring rates but there are more factors than that that will impact my ride height and stiffness. Which is not to say that spring rates are unimportant (obviously they are) it's just that there are other factors in play that you do not seem to give any weight.
And you say that there are different rate springs side to side. Not according to Honda. Front fork springs on our bikes are the same side to side. Now, the ends of the springs are usually more progressively wound on one or both ends depending on the application, but they are the same side to side. Once again, as with your sprocket statement, you are in conflict with Honda, as well as with me. But soldier on, there.
Do us both a favor Oyanun, please stop with the text book specs. They do not seem to be coupled with any real world experience. I would really prefer that responses to my posts be based on real world experience. Because real world experience trumps theory, especially inexperienced theory...........every time!
