What is the proper air pressure for the front forks on a 1986 Kawasaki 454 LTD?Thank you, Ric
My 2000 Harley E-Glide has air-forks up front and air shocks on the back, the air valves for both are just behind the right saddlebag lid on the rear fender strut.Joey- many motorcycles, including the 1985-88 LTD 454, use compressed air in the upper part of the fork to allow the rider to adjust damping, in the same way the pre-load adjustment allows the rider to adjust how the rear shocks act. The lower part of the fork is identical and holds conventional fork oil, while the upper part of the fork is made air tight, and usually there is a balance tube between the two forks to keep the pressure equal. A simple tire-type air valve either in the balance tube or the fork cap allow the air to be added.
As the valving on fork dampers have become more sophisticated air assist forks have become less popular, but they were quite common on Japanese bikes in the 1980s and 90s.
