I just bought trike in feb this year an 09 and set it at 30 lbs then toddy put up to 40 and found ride much better. I weigh 215

 

Got my Tri about 2 months ago. Bumped up the shocks to 50, and 2 hours later they are down to 40,and that's just sitting in the garage. I bought used...only about 4000 miles on the 2011. Could the previous owner blown the shocks? Is this something the dealer should have checked out before selling it to me? I do use the HD pump... If I need to get new, any ideas on OEM?

 

I don't believe the shocks are blown. Possibly you have a leak at the connections on the shocks or schrader fitting. Get some snoop and check for leaks.

 

Does anyone know if one of these will work left attached to the shock valve so I don't have to remove the panel every time I want/need to change/check the air pressure?

 

That should work. Use some type of sealant at the connection. We run our shocks at 38-40 and our rear tires at 22-24 psi. You REALLY have to play with both to get the ride you like on the roads you drive. The shocks handle the bumps and the tires adjust the ride quality.

 

Some people have had trouble with the hose. I think it involved sealing, but I can't remember. It should work tho. Be sure & check the fitting for an "O ring" to seal with, or use Teflon on the threads.
There are other kits that have a gauge & Schroeder valve & release button that fits in the tour pac, but they are spendy. like around $120 or so. They are made by Wheeldock Ez-Air Systems.
They are sold by these people: http://www.moto-xpressdlr.com/wheeldock-EZ-Air.html

 

I have an extension air fitting that I bought at the Harley Dealer
Air Valve Extension, Part # 42300009. I have it routed around the grab bars and it sticks out about 2" and is always there. I do not have to remove the cover to check shock pressure........

50lbs is max on the Freakwheeler.

 

Thank you Bob, I bought one and as you said it works fine and I have it poking out between the seat and the cover which is a lot easier to access, I'm a well happy bunny, thanks!

 

That looks like a great idea. Going to get one.

Oh, since the thread is revived; you actualy can use your big air compressor just fine without harming the shocks if it has a regulator on it. Just set the regulator pressure to what you want in the shocks. Hold the chuck on until you don't hear any flow; ta-da, you're at that pressure! It can't go any higher. No need to check it or anything (as long as your regulator is accurate, check first!)
