i-click i had 9.5oz and 10oz come out of my OEM 12" shocks. I refilled them to 10oz each and they have held air and have run great (Amsoil #10)

I also used 10oz in the 13" OEM shocks prior to the sag adjustment.

 

No reason to dis the OP because he did something "different" or inovative to his own scoot. Kudo's for posting...

Thanks. I just made a note of that.

 

I was given a set of 12" '09 SG rear shocks, just the other day...

I researched quite a few threads, including this one, and found that no one was quite sure how much oil to put in each shock. When I began, I drained the shocks into a measuring cup. (Wife complained when I asked her to hold the funnel as I was adding the new oil!). Anyway, the box they came in, was saturated with oil. The previous owner did plug the holes, but without sealant or teflon tape. One shock release just a little over 7oz., the other was right at 12oz.

As I figured certainly no oil was added to the shocks after removal, I chose to believe 12oz was what came from the factory, so that is the measure that I used to fill each. I'm a pretty hefty boy at 5' 11" and 300lb. Figuring that in, I figured I could always try the method posted earlier in this thread to dump some out, if I feel like trying a bit less. All depends on my ride later...

I used the bead breaker arm on my home made tire changer to compress the shocks, both filling and draining. Worked flawlessly, took about 20 minutes total to drain/fill, and gave me a little just more pride in finding a new use for something I had made myself.

Had a hella time trying to get one of the old lines to seal in the shock fitting, but finally it is holding pressure well. The hose just refused to go in far enough to seal. I simply had to show the fitting that I had more will than it did! Haven't been on a ride yet, so I'll have to see what it feels like later.

Oh yeh, I used some 10WT Honda Pro Suspension oil. I hope the bike doesn't care, but since everyone says these shocks are made by Showa, and the oil is also, I figured it couldn't hurt. If the bike becomes buck toothed, and big eyed in the future, I'll let y'all know!

BTW, when I was reading the label of the 5wt, it said it could be used where any ATF was required. So, that tells me that ATF is perfectly fine for use also. I chose not to, because I could find nothing about ATF weight properties. Closest thing I found said that lately, ATF weights have gotten down to as low as 4WT, for use on newer vehicles.

dagnabbit!!!! didn't notice that this thread was older than dirt. i hate when that happens

 

And others bitch cause no one uses search to get answers...

I figured I would add my thoughts at the end of this one to demonstrate what I was saying. Hope you had fun reading through all the old stuff though!

 

I got 6 ozs. out of my 12 in. SG shocks but replaced 7 ozs. with the Amsoil shock therapy #10 they have no leaks I think they weren't filled @ the factory correctly maybe should have more oil maybe not I run 22-25 lbs. 2 up & they have never been so smooth since new! Good Luck With Yours.

 

I changed mine way back by using a large veterinarian plastic syringe to suck the fluid out and push back in took only minutes actually took lot longer to remove the shocks hen servicing.Bike felt better especially on the bumpy road rear wheel bounced lot less then before.Oh I used KYB racing shock oil.
