• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

My solution to 2021 ACS Compressor issues - a re-engineered custom anti-vibration bracket mounted in the RH Saddlebag!

Just like many other Spyder owners, my ACS compressor failed and the suspension system could only be maintained manually. My dealer said a compressor replacement would cost $900.00, but would not guarantee it would not happen again. After much research, I decided to tear into the project to see why the compressor failed. The the inside of the compressor motor was very rusty and eventually caused one brush to lock up to the armature. These motors have no seal or gasket. They are placed on the frame in front of the rear tire and subject to all weather elements.

I like the convenience of a system that automatically adjusts the ride height, so I decided to not only go to an after market compressor but to move it to a more controlled environment. Now that this re-engineered system has been tested, I can approve it. I purchased a Viair 95c 12 volt, made a custom anti-vibration bracket and mounted it inside the right saddle bag. The hardest part of this project was removing and reinstalling the Tupperware!

Now, if I have compressor problems in the future, all I have to do is open the right side saddle bag.

The open compressor is not the only fly in the ointment! The dump valve is another key problem - it will get gummed up and stick open just enough to cause a slight leak and make the compressor work overtime! The non-limited bikes have the manual fill setup, with the same shock as you're running right now; the only difference is that your bike see's the change in weight and adjusts the air bag to maintain a given ride height, yes, to a point, but what it is also doing is making you ride softer or firmer, and that's what it reads on the display!

I found that when my system was working, I was pleased with the ride once I got it set to the desired firmness, and I didn't ever change it! When I found out how much it was going to cost to fix it, I woke up to the fact that a manual 'set it and forget it' was great for me and it's still that way working fine! Simple and easy! So, when you are putting your compressor away in a safe place, put the dump valve where you can clean it from time-to-time also! :cool:
 
@Mikey, that is exactly why I decided to move the compressor to an area away from moisture and dirty air which will clog the compressor piston and dump valve. This system should have never been allowed to run in a wet and dirty air location.

I find that the compressor is just extra baggage that isn't really needed. It works for the fine as a manual fill for the nonlimited bikes. But that's just me, not to mention it only cost me $5 to do!

Poor engineering and poor design strikes again. Imagine that?
