Re: Fork spring change.
If they are racetech, go on their website and see what the correct preload should be. You then measure the depth of the fork from the spring seat to the top at full extension. Then measure from the lip of the cap with the preload adjuster backed all the way off, to as far as it extends downward and the length of the spacer. That is the legnth that a spring would be at zero preload. Measure the spring legnth, it will be shorter. The difference is the preload, it will probably be more than you need. Now you know how much you need to cut the spacer to get the desired preload. If you end up cutting the spacer and the part that you tossed had a hole in it you need to drill a new hole for oil/air to escape.
