How to adjust rear shocks on Kawasaki Vulcan 1500 classic 1997?

Use the largest Phillips screwdriver that will fit in the adjustment hole( there is more than one adjustment hole for turning the shock - counter clockwise is to decrease weight= a softer ride ---- clockwise is to increase rider weight

capacity.

clockwise depending on your weight. #1 softest = #5 Strongest.

a 150lb. rider is #2 for an example. MUST ADJUST BOTH SHOCKS EQUALLY because of handling and tire wear. ( simply press screwdriver left or right -- your not turning the screwdriver -- your turning the complete shock!
