Rear shock air pressure

DO NOT USE A COMPRESSOR!!!!!!!!!!!!!!!!!!!!!! You will damamge the system.

I have run anywere from 5 - 40 lbs. much smoother at lower pressures.

Also - not sure how you can blame the dealer on the pressure in the air shocks.
 
The Harley pump is a very fine tool. It fills the shocks quickly and accurately.

I went to 35 PSI today and my wife didn't notice any of the usual bumps!!

Was set at 20 during tune up.
 
You can use a compressor if you know how to operate one that has a regulator on it.
If you set your compressor for 40 PSI MAX and your shocks take 50 PSI MAX how can you ever blow them out?
Sounds like operator head space and timing to me.
I would NOT use a compressor that you could not regulate.
How much pressure should I run with a CT on the back?
 
Hopefully this won't be considered as changing the subject matter but anyone running with progressive 416's , whats the preferred air pressure? I'm running 5 lbs solo.
 
Based on this thread I have done some testing with different air pressures, solo riding, with10 lbs of crap (tool kit, additional helmet, air pump, rain suit, plug kit, CD's etc.) with me.
I weigh 220 lbs (OMG I've put on 20 lbs of weight in 2 years....)

24psi - bottoms out frequently on small moderate bumps;
28 psi - still bottoms out frequently but on harder bumps/ruts;
32 psi - bottoms infrequently and only on really bad bumps/ruts-- handling stiffening up a bit (better handling);
36-38 - no noticeable bottoming out, but rebound is becoming more harsh, however handling is the best at this pressure.

So what does this tell us? The roads in Australia suck......
 
I totally agree. This should be a stock issue item just like the small multi-tool they're issuing now.

I've got a small 12-volt tire pump with a built-in guage. I weight about 190 and my wife is about 110. I try to keep it about 25 psi and have never bottomed out once with my Ultra Limited.
 
My '10 SG came from the dealer with 10# pressure and the wife and I bottomed out quite a bit. (combined wt 310). I bought the HD pump, (actually one of their more reasonable priced items) and went for a ride. We followed the same route and would pull over to make small adjustments until we were satisfied. Both of us with loaded bags need 35-40. Solo 25 is fine. I don't see how you can monkey with this without a precision pump though.
 
Yes, I just found out when I got my 2011. I had a 2006 and the PSI settings have changed a lot on my newer bike. About twice as much pressure recommended on the newer bikes...
