[QUOTE="davidd, post: 121922, member: 1177"] Howard, It sounds like you have had great success with the rear suspension. Fortunately, the rear suspension has a lot of movement. The front does not. It is not easy to get a full range of comfortable spring in 3" of travel. Most bikes need somewhere between 600-700 lbs. to resist bottoming out when the front brake is grabbed when two-up and at speed. At the same time, we want the springs to be light enough to absorb ripples in the pavement. It is a tall task. As far as I know, the best front suspension set-up is the coil-over. When Carleton Palmer installed his he said that the "harshness went away." I suspect this is due to the differing motion ratios of the spring box vs. the coil-over, but I am not certain. David Tompkins noted the improvement to the handling of his racer at Laguna Seca with the coil-over and the Reg Bolton type modification. Just for information, Ertalyte TX is a good bearing plastic that is oil-impregnated David [/QUOTE]
