Bought a set of 2010 Streetglide shocks at the swap meet.  I need to know what the psi is for these shocks.  Didn't the raise the psi after 08?  I have a 08 service manual.

Thankx Eric

Literally put what ever psi it takes to keep the bike from bottoming.
10-80psi.
HTH,

I run any where from 25 to 50 PSI. If your OL on the back is a little on the healthy side you may need more pressure than the 50 PSI I use.

My '05 I never ran over 30 PSI.

Those same shocks, I have run 80 to 100 psi on a fully loaded touring bike for trips.  never had an issue doing 600 to 700 mile days.   
just to clarify, I do run a compressor underneath my battery hold, and capable of pumping to 120 psi.

My 2010 Service manual say's 50psi Max... For all touring models

It's about product liability insurance not functionality.

As JohnCA58 stated he runs up to 100# with no problems...me too, for at least 100k miles on 2 different bikes...just much better ride quality.

Earlier bikes used stiffer springs and a bit difference mounting angle changing affective wheel rate...requiring less psi compared to the 09-up baggers.

When running down the road reading the gage (with an on board compressor) the pressure reads higher than when checking the pressure on the side stand.  As soon as you sit on the bike the pressure will rise up to 10 psi and more with a passenger and gear.  When you hit a bump the pressure spikes, so the 50 psi max is more theoretical than actual.  I have also run up near 100 psi for many miles fully loaded and have yet to see any leakage or other issues.  Like the man said pump it up till it quits bottoming out, 50 psi max be damned!

You can monitor your suspension movement with the gauge. Change the pressure and watch the effect. Having an onboard compressor...hands down one of the best upgrades to ride quality especially cross country where road conditions change frequently...and the pressure gauge to monitor is handy to watch for air leaks, max travel of the suspension,etc.

Which compressor and gauge and bleed-off valve (electric or manual) setup do you have??

   Yep  on Gracie ('01 FLHR) I typically run 15 in the front & 18 - 20 in the rear (riding solo) and 18-20 / 25 when 2up

This is the first time I've heard you can put more than 50psi per manual.. That's good to know, Thanks.. I know the stock rear shocks aren't the best, gonna try and add extra psi and see how it feels...

I had the 20K rip off service on my 7 month old FLH last week. They pump to 25PSI and instructed me to not go above that (I had 40PSI). Idiots!

On my '09, I have experimented with different pressures. Solo riding  with  2 almost full saddlebags (I carry 3 + Harley tool pouches, first aid kit, rain gear and other assorted gear), I use about 38#s. I weigh about 180.

I weigh 250 plus and around 30-35 works for me. I bump it up when fully loaded to ~45-50 psi.

If you ride without bottoming and less pressure it bottoms...IMO you are @ the best pressure for the current road condition.

I've never had over 35psi in shocks,never bottomed out at that psi.. Only time I've ever experienced bottoming out is when I tried the FLHX shorter shocks. Either solo or two up... I weigh 235lbsand wife 115lbs.. So I guess there's no need to try and blow my shocks with 100psi.....

Ohlins !!!!

Ohlin are great,  but not everybody has the coins 7 hundred something a set from Howard to run Ohlins.

That's correct...it's been done and no blowups or leaks...just a board-stiff ride.
Again, whatever the least psi to keep the bike from bottoming from road conditions is best ride...and that number changes with conditions...including weather (temp)...it IS air.

Thats for the #3 shocks. The #2 are just as good for 2 hundred or so less.

Didn't know that, he was recommending the 3-3 set up for me,   I went and built my own air ride for less than 200 and has been great for the last 4 years now and has the slam look when parked.  has 4.5 in of travel.

Cool. That sounds like a nice setup. I ran the legends air ride for a few years. Grew to hate it once i really stepped on the motor.
The #2 are still a great shock. infact for my customers i prefer the ride and simpler set up.

  for Ohlins! Great company. Used to work with them in the 80s-90s. in my auto roadracing days.

But are they state of the art?
