I've picked up a nice 81 KZ550 LTD with 20k and put about 3k miles on it. The front air shocks don't hold air very long. They only take about 10 psi so it would be nice if I could use a small hand pump with guage attached and "Y" manifold hose to connect both sides and pump. Then I could top off before each ride. Does anyone sell such a setup.
