Preloaded means you would make an adjustment that would put a load on the shock, spring with a coil over. This would stiffen the shock and would shorten the available travel causing a rougher ride. This is needed if you are riding 2 up to keep the rear tire from rubbing the fender when the bike is under heavy acceleration or running turns at a faster speed. If you are preloading a coil over shock the adjustment is towards the bottom of the spring. Make sure both sides are set in same position.
you can adjust the spring preload just loosen the nut at the front of the shock but not eather of the mounting bolts its the biggest nut on the shocks to increase the preload using a spanner wrench turn the shock adjusting plate toward the jam nut that's the small mounting nut at the front of the shock and to decrease the preload turn the adjusting plate toward the mounting bolts at the rear of the shock do the same amount of turns to both shocks and then tighten the jam nuts.
yes
All you can adjust is the preload. You need a spanner wrench. http://www.xs650.com/forum/
Softail shocks are under the transmission. They sit horizontally and are inline with the chassis. Unlike the shocks on all other Harleys, when you hit a bump on a Softail, the shocks get longer instead of shorter.
Typically Nitrogen in factory produced shocks, Or compressed air in motorcycle adjustable air shocks.
A normal motorcycle has springs built into the front suspension. You may not see them because they are inside the forks/shocks.
John is about to preload his truck with logs.
it decreases blood volume and preload
Preload is caused by decreased blood volume in ventricles. Therefore, decreased preload directly caused by bleeding, polyuria, dehydration.
if you find out tell me what preload is
more than likely it is out of fork oil, or something is broken inside the fork.
Preload is the amount the pinion bearings are squeezed together by the pinion nut.
