It will raise it up to about an inch but the ride will be worth it, experiment with different pressures, if I remember on my 1500 two up with the packed for a two week vacation I ran at 65 and just two up 50 and single I think 35 and as far as height can not remember any difference just ride comfort.
I owned a 84 1200 Aspy and had the same problem. I thought about buying a kit and repairing the problem. Old parts have a way of repeating the same problem.
A friend had motorcycle repair shop. Found a pair of shocks with outside springs the same length from a heavy bike. Had 5 adjustment positions move it up or down and find the ride for you.
Never had a problem after that. I ride a 1500 Bobber with the same set up. Riding it for 15 yrs with one black box for the ignition. Head mechanic at Honda shop said it couldn't be done.Cost him a steak diner.
