Stopped by my local "stealer" today and checked on what they charge for a 25,000 mile service. I have always done my own. They said it was expensive because they had to change the oil in the front shocks as well as a lot of other things. I cannot fine anything aobut changing the shock oil. Are they just trying to rip me off?

 

Changing fork oil on a non-air dresser takes at least 2 hours of labor.

 

Lots of info on here about changing fork oil. If you can't find anything try searching iclick's postings. I used his method to do mine.

 

You have conventional springs on your 06

 

It's not to hard if you can turn a wrench.The forks dont have to be removed like the manual shows.

Also it's a good idea to change the oil sooner than what the manual sez.
Changed mine at 40000 for the 1st. time.The oil was blacker than black!

 

I'm pretty sure iClick has posted a great piece on how to do it yourself. Didn't sound too hard reading it, as I want to change mine out to a heavier oil for more dampening.

 

my 06 is ready for this too. let us know what you do.

 

I have also followed iClicks method of changing the front fork oil and added the SE "Heavy" PN: 99881-87 fork oil with positive results. Here's the thread in question.

 

I put the heavier oil in mine and it rode like a tank. Changed it back to the 5wt and it rides smooth again. If you want a stiff front end go with the heavier oil,for a smooth ride stick with stock.

 

My experience was just the opposite. With the stock fork oil the front end was soft and wanted to wallow, not smooth. There was a lot of front end dive when braking also. The "Heavy" fork oil (not the "Extra Heavy") fixed these problems and was not too stiff. I have sense installed the Performance Suspension Drop-in lowering kit and dropped the front 1". I used the SE Heavy oil with this setup and now I have no front end wallow, brake dive and a smooth ride.

It looks like you have a RK. I know at least some of the RK's have a cartridge in the forks. This may make the difference.
