My '16 TriGlide has about 1200 miles on it. I've been checking the air in the suspension. It seems to loose all air pressure overnight. Is this normal?

 

It's not normal, you either have a line leak or a shock leaking. Take it back to the dealer and have them find the problem.

 

Are you checking the pressure and it's down or is it sagging. Had a similar issue with mine. I was checking it with a tire gage and filling it with an air hose. Was told by the dealer that you can't check it that way. Bought the hand pump and no more issues. Always the correct pressure. If it is sagging then forget all that I just said.

 

I have the HD hand pump. I found the tire gauge didn't work as it let air out as soon as I put it on. I put about 22# in last night using the HD hand pump and this morning I checked and there was no air in the shock. That has happened before, too.

 

My 15 did that. I also had a slight oil drip on one shock. Dealer replaced both.

 

Definitely a problem. Let the dealer find it

 

My 13 leaked.air line was not pushed in all the way in at the shocks

 

I had a slow leak on the my 13, dealer was going to replace under warranty but I purchased the Progressive shocks, and dealer installed with no labor. Never regretted that move. The progressive shocks provide a much smoother ride. The wife still says it was the best mod we have put on the trike.

 

same here but only 1 shock needed replacement

 

Slight drip on left shock but no loss of air pressure. Left shock replaced and all is well.
