Hello, I have a 2006 Ultra, I was looking in the repair book and it says I need to pull the forks to change the oil, I thought I have read where some of you where able to do this without pulling the forks. Just checking my options before I start this project. Thanks Al

 

How many miles do you have at this point?
I love working on her but thats one job I'd give to the dealer....
I'm going to drop some progressive springs in there at that time too to stop that whole diving down issue...

 

not to steal the thread - but i read that heavier oil would stop the diving down? Do ya really need the springs or is that just something you are adding to make it even stiffer?

 

Not trying to hijack this thread either, but my '99 RK has the front air shock. does that need an oil change, same as the newer bikes?

I'm at work with no manual.

 

There's an excellent write up somewhere around here on changing fork oil without removing the forks. Basically, you need to remove the ignition switch and inner fairing cap, remove the top cap on the forks, and the drain screws on the bottoms. Pump them really well to let the fluid drain out. Put the drain screws back in and refill with 10.8 oz. of fluid. Pump the front end repeatedly to burp all the air out of the damper rods, then close the forks up and put everything back together.

 

Its easy to change oil and if you change the weight of the oil it will change the dampening characteristics of the forks also. I am currently running 90wt amsoil in mine but it is a little heavy but it took care of the dive. When you change the oil have a good measuring cup and make sure you get the right amount in there. There are two amounts, one for wet forks and one for dry forks. If you don't disassemble the forks use the wet number.

 

I did a write-up here (scroll down to Post 23). It outlines how to change your fork oil in about an hour without removing or disassembling the forks.

That thread above should answer any questions. Fork oil change made easy and less than couple hours of time required.

90wt...That's got to be brutal
Do you need that heavy front fork oil in Alaska?

+1 aren't most fork oils in the 5 - 15 wt range?
