Rear shock oil amount
« on: July 24, 2006, 07:29:15 PM »

How much oil do the rear shocks on a Bagger take? I was told 12 ounces
but that seems like a lot. Next, how do you fill the shock?

So says the manual. However I've been in there before. I have this figured out now. It is 12 ounces of oil. A quick call to Legends service line confirmed that. :)

OK why am I doing this? My bike has been riding real harsh lately. Wait let me back up for a moment. While chasing my low speed wobble I decided to pull the top tree and get directly to the bearing. Well since I was that far I decided to change the fork oil. I figured it would be easier to pour the oil down the tubes as opposed to pumping it back up. Which brings me to needing to know front end air pressure. I tried 20 pounds than 17 pounds and while riding this weekend the bike felt worse than my rigid. The rear air ride wasn't helping at all. So this afternoon I pulled the air ride off and installed my factory rear shocks. I bounced around on the various boards and came up with a satisfactory air pressure for the front end. With the lower air pressure in the front and the stock rear shocks this thing rides like a bagger is suppose to. :) Now the old shocks. My Legends air ride is the old style that used stock shock housings. Taking them off I spilled some oil on the floor and thought nothing of it. I placed a shock in the vise and I couldn't push in on it. WTF? I grabbed a dead blow and gave it a smack. The piston pushed in and oil shot out. I was now able to push the piston in by hand (not easily). Now that I spilled some oil and pushed some out I had no clue how much was in the shock. So I drained it all. I drained around 8-9 ounces but I couldn't account for the spilled fluid. So started my search for the fluid amount. I recall reading somewhere where it took 12 ounces but I was not 100% positive. After coming up dry I called Legends and the tech there confirmed that the shocks take 12 ounces. Well it took me close to an hour and a half to put 12 ounces of oil back into the shock. That sucked. At this point I had enough, the bike rides real good and I called it a night in the shop. So when I get ambitious again I'll go out and install the Legends back on the bike and test it. If it went bottoms up I'll run the stock shocks until I decide what I want to do. Legends will upgrade me to the new billet shocks for $800. Those stock shocks aren't so bad! ;D

12 seems right from what I remember.  But you should only have someplace about 6-7 (that's right SIX to SEVEN) pounds of air in the forks.  At 15, they're not compressing at all.  The manual states for every 25# of rider weight OVER 150#, add 1 (one) pound air and for every 10# luggage add 1# air to a max of 25.  Whenever we get near 15 on her SERG (and it was the same on the 01 ultra I had), the front stops moving completely.  Oh yeah, the only way I could fill the shock was pouring the fluid in the top air hole.  VERY SLOW. [smiley=drink.gif]  There was definitely alot of cold beverage time during this procedure!

I'm at 15 pounds in the front now. I'll drop it a couple and see how it responds. I can always add more!

The rear is hooked to my compressor. I like the ride so much I'm in no hurry to test the air ride out. I may go and pick up some 5/32 air line fittings so I can plum the shocks into the old fill valve. This way I could check the pressure. :)

Very slow does not describe how long it takes to fill the shocks. If I were a drinking man that would have been a couple of six packs as far as time goes. ;D
