RT Ltd RearAir Shock

[oldguyinTX]

Does anyone out there know if air should be added to the rear air shock on an RT Ltd? I know that there is an on-board compressor, but I also notice that there is a Schrader valve under the seat. Is there an ideal PSI for a given setting? The manual is somewhat ambiguous about this, and I am not sure that I feel any difference at different settings. Any ideas?

The onboard compressor will handle the air as needed. The Schrader valve is for releasing the air from the airbag when needed for maintenance.

The ACS system is more about ride height than rider comfort. That's why the ACS sensor is attached to the swing arm. More weight on the seat and in the compartments calls for more air in the bag to maintain a certain ride height. Empty the compartments the ACS will probably let air out of the bag. Ride solo after riding two up and the same will likely occur. At least that's been my observation.

The Schrader valve, in addition to the post above, is a handy place to check the pressure if you really want to know what it is or add air if your compressor quits (just don't exceed the limit). It's also the only way to get air into the system for those models that don't have an on-board compressor. As far as an ideal setting goes you're right about the table in the operators guide.

Make sure you don't have this problem

The height sensor arm seems to come with the screw not present. Got my 2014 RT-S this way, finally figured it out about 500 miles in. The rear suspension felt like it never moved when adjusted. Dealer I took it to said they are supposed to check this upon delivery. But the two dealers I've dealt with seem very behind on the mechanic knowledge side of the spyder, so I can see that happening a lot.

...Just lay your thumb on the button on the dash, and all is fine... :2thumbs:
(It'll only work, if you're in gear amd moving.)

Good advice, I have not yet asked the tech that works on my :ani29: about this. Just wanted to get a consensus as to what the PSI should be. Will ask the tech tomorrow. Thanks!
