[QUOTE="KawieKX125, post: 69378, member: 20140"] Jeremy, I have a 99KX125 and have been going crazy with the suspension. I am 140+- some pounds and ride a supercross style track with some HUGE jumps, SHARP rocks, and some fairly gnarly chop in and out of turns. I have installed 250 stock springs, run 8 mm preload in the forks, 95mm sag on the shock, and a 95 mm oil height, and 5wt oil. I have the comp clickers almost at full soft, and the rebound in the middle. The suspension absorbed small bumps well with the stock springs, but bottomed really hard over almost all the jumps and kicked me front end high. the 250 springs are not bottoming much at all(only when I case or overjump), but they are harsh over small bumps. They are not rough, just firm, they don't absorb crap to be blunt and it is beating me up over the rocks and the bumps. I am torquing the clamp bolts and the linkage bearings are in perfect condition. I know that if the progressive sprngs stinkbug, they become very harsh because they run in the stiff section of the spring, but in the video that I have of me riding, they are in the top 0-3 inches of travel when I am going over the problem areas. I know you may say straight rate springs are in order, but I think for the bottoming resistence that I will need(ie, very stiff spring, like 250 spring), the initial part of the travel would be much stiffer and harsher. Please recommend spring rates, oil heights, oil weights, preload, etc., I would really appreceate it if you could also explain why these recommendations are made. Thanks. Also, I can not afford revalving at this point, and if I got it revalved in the future, would I need to get another set of springs other than the ones that you recommend now to go with the revalving? Thanks again ------------------ [url="http://albums.photopoint.com/j/AlbumIndex?u=1466260&a=11046272"]Aaron's web site[/url] [/QUOTE]
