1994 GL1500 Interstate, not designed for air in forks.
I've been wanting to upgrade to progressive springs since I bought this 'Wing a year ago, but ya'll know finances......
After reading several items that changing the fork oil to a heavier weight could improve the very soft ride/cornering characteristics, I decided to give it a try.
Buddy Mark Z showed up, we removed the forks, dumped the very black oil out, cleaned them, added new seals & wipers, 20wt fork oil, and re-installed. Well, they ride and handle the same, except for the fact that if hitting a small bump while braking, they bottom out. Loudly.
After us cussing/discussing the matter, the only thing done differently was by me. As in the past on other bikes, I added the fork oil around the shaft, before installing the bushing, seal & wiper. Mark & others add the fork oil thru the small bolt hole from inside the axle mount.
The proper amount of oil was used, 10.8 / 10.9 oz as specified in the manual.
So, where did I go wrong? Ideas?
TIA
