It's a beautiful looking machine, absolutely NO road rash, but I have NO maintenance history on it. I have not yet ridden it, as a matter of fact, I have never ridden a motorcycle before, but have already done a compression chk,, done a borescope inspection, replaced plugs, engine oil, trans oil, primary oil, adjusted final drive belt, adjusted primary chain, serviced shocks, replaced frt & rear brake pads, changed brake fluid, & now am looking at the forks. Your sage advice has been utilized where applicable, & again, thank you to all. Ric Lang..........PS As I mentioned in earlier thread, I'm an FAA aircraft/engine wrench, so that's why all this manic stuff is going on.

If the fork fluid in your bike is original, it will probably be black. That doesn't mean its contaminated, it is just the stuff that Harley used back in the day made the fork oil black.
You also may have a cartridge in one side of your forks. Drain and measure each fork oil quantity, the manual is really flakey when it comes to refill quantities.
I think they make it so convoluted and complicated so people will take the bike in for fork service.
My 06 Road King was supposed to have conventional forks but had a cartridge in one side.
