I believe my service manual for my 04 Ultra says to change the fork oil every 20,000 miles. What does the 06 service manual say. It seems that 20,000 is too often. Is there a need to change this oil at all? I've been wrong before but would like your input.

I change mine every 10K. Why? Because it's easy and I'm anal.

What year is your bike and what is your method of changing it? My Ultra is an 04' and it's a time consuming pain in the azz.

Had to look it up since my bike is fairly new. 2005 Road King, the manual says 50,000 miles.

Geezer, do you have a special method? It looks like a several hour job by the service manual. Any shot cuts would be appreciated.

The 50,000 miles that Sloxl stated his 05 Roadking manual states sounds more like it but I don't know if the seals break down or why you would need to change it at 20,000 miles. There is no heat to speak of but are there other things that go on in the forks that would cause the oil to break down?

I do mine bout every 10,000 miles. I dont think the oil wears out, but I've noticed some nasty watery oil (probably from condensation) coming from mainly the left fork. I also have changed to a heavier fork oil in hopes of avoiding any future front fender damage from bottoming my shocks in some of these 4 inch deep potholes around here.

Not to stir it.... but an interesting circumstance comes to mind.

I being the anal type, took my scoot 1996 to a local dealer. I paid $125.00 for a fluid change and inspection. Since my scoot was a rebuild, I considered the money well spent.

Anyhow, the scoot passed nuster. Then the tech told me that they'd be available for my 20K, And to remember that "they" take care of ther fork oil.

What resukted is that my fork oil is still fine.

Maybe it was the sales pitch or the voice of the salesmen///// but those folks sure struck me as a rip-off.

It's a piece of cake if you have a frame lift. Drop the front wheel, fender, and outter fairing. Pull your fork tubes, run down to your local HD, hang out and B.S. with the guys for about 15 mins, pay the service guy, run home, and reassemble. Total time? about 2 1/2 hours from start to finish. Did it yourself, didn't pay a ton of $$$ to the service dept. and you get to know your scooter even better.

Foaming. Any oil will break down after repeated "usage." Even hydraulic oil. Since mine is lowered, I'm using the SE Fork Oil, a little heaver than standard "E", but helps to keep it from nosing over.
