Had my '14 TriG for about 3 months now, and it seems that the system is losing pressure. Didn't touch it since I got the bike; trusted the dealer to set it up right since I told them we would be riding it 2 up a lot. Never had any issues. Installed the DK Comfort Lift kit, and was impressed with the improvement in ride quality and steering response. Now have about 4500 miles on it, and yesterday noticed that the suspension was bottoming out over minor bumps 2 up. Close to the dealer so we swung in; being Sunday there was nobody in the service dept. but I picked up the HD suspension gauge/pump. There was only 10 psi in the system. Pumped it to 36 psi (yeah I know that is more than I should need but I wanted some room) and rode the rest of the day. Checked it this morning and it is at 30 psi. I know it is cooler now so I expect some decrease, but will keep an eye on it.

Anyone else have any issues with their rear shocks not holding pressure? I have been looking over the forum and didn't really see any posts about this, but seems like there has been interest in the MotorTrike air compressor kit; I am interested in that as well, but don't want to invest in a $600 band-aid if the MOCO system is leaking down.

 

Had the same issue with mine. Need to reseat the air lines at the shocks and fill valve. You can use soapy water to find the leak or just redo all the fittings.

 

I can do that but maybe a job for the service dept.? Warranty and such. Of course, I will be trusing them to do it right...

 

There isn't much volume in those shocks and a cool down in temps will drop the pressure some.

 

I put my RK shocks on my Nightster. I put a guage on and filled to 44#, rode 2 up(260+160) 300 miles plus my rides, it would peg past 60#. Never rested below 44 for 4 weeks now. redo your connections. don't trust dealer to do it right even though it is simple. I ran more fittings and line also. no reason for trike to be different.

 

A few things affect the PSI reading on the shocks-

• Ambient Temps
• Riding will heat up the shocks and show a higher PSI
• Weight on the bike...if you put 36 lbs in it with the passenger On the bike, then take a reading with them Off the bike, it will be lower.

Gotta take all that into consideration when comparing.

If it is leaking, I would have them fix it under warranty.
