Electronic air

[Highwayman2013]

Guys, there is no valve under the seat! That is part of my point. There is no way for the owner to deflate or inflate this system.
Thanks,

Ok, didn't know that. My 2016 has a valve and no compressor. At least you could look underneath and see if the air bag is inflated.

Gentlemen and ladies,

I am going to put this one to bed. From everything you folks are telling me--there doesn't seem to be a simple way of checking to see if the 2017 F3 Limited is indeed operating the way it should be. Yes I could perhaps drain the air bladder but certainly not without knowing if BUDS would be needed in order to refill/reset the system. Bob said he heard the compressor running at low speed on his 2018 RT and also heard it releasing air. I have not heard/felt anything from my electronic system either alone or 2 up---but I might not be able to hear at that frequency. I would like to thank all of you for your participation in this discussion. I am going to assume that there is no simple way to check this.
Key word--simple.

Thank you all.

Do you have a button somewhere, that allows you to adjust the ride height?
If you do: set it on "Max", and pump the system up fully...
Take it for a ride, and leave it parked out in the hot Sun...
After an hour or so: start the bike, and have someone listen to it at about the mid-point on the RH side...
(By the seat...)
When you put it in gear, and slowly start to roll: they should hear it bleed off the extra pressure gained from sitting out in the heat. :thumbup:

Sorry Bob, no button of any kind.

Thanks,

"I am not sure if after you deflate it, that you then need BUDS to reset it or it just reinflates after you start it back up so I would not try it until you know for sure BUDS is not required."

So why would I want to go to all that trouble just to try and verify that the system is or is not working? I am looking for a simply way to visually see if the system is
functioning as it should. If not then I could proceed with some trouble shooting steps.

BTW what manual are you using??
Thanks,

Try using a ruler and measuring from the rear mud flap to the ground, take the measurement under a few different scenarios, 1-up vs 2-up, etc. If the measurement stays the same you could reasonably assume that the system is working.

The answer----

Hi Bob,

I need to answer the second question before the first, as the ACS Sensor would have to be connected to perform a little trick to bleed the ACS air bag a little bit...

You never have to disconnect the ACS arm from the swing arm unless replacing the sensor or swing arm. The shock tops out long before the sensor is over extended. In fact, you don’t even have to disconnect the arm when replacing the shock, as the swing arm will contact frame components prior to over extension...

So, to trick the ACS into bleeding off some air is to jack the rear wheel high enough that there’s no load on the rear suspension. You can lift the wheel slightly off the ground if you’re not sure all the load is off. Now, to activate the ACS system, the engine must be running, park brake off and transmission in 1st or reverse gear. Sit or stand next to the bike so you can keep your foot on the brake pedal, for obvious reasons... Lol The ACS will think the ride height is too high, and you should hear the pressure valve release air in a series of hisses. Once it stops, put the bike in neutral, activate the park brake and lower the bike back down and remove the jack. Seat yourself on the bike, put back into gear and park brake off, you should hear the ACS pump and the bike lifting in the rear...

If nothing happens during any of this, make sure the ACS Sensor is attached to the swing arm or a fuse hasn’t blown. If all that is okay and still nothing, have your dealer connect it to BUDS software and check that the ACS system is activated. I’ve had more than one RT come from the factory with the ACS not activated in the system. So far, we’ve had zero issues with F3-LTD’s ACS systems.

Hope this helps you out!

Be safe in your travels. Take care.

Sincerely,

Shawn Smoak

Needless to say I thanked Shawn for the above answer,

I think he already answered that.

Is it safe to assume that you also don't have a tire valve under the seat where you can check the actual pressure in the bag ??

Easy Rider, do you just get a kick out of being a dick? There is no need to answer that question! :shocked:
My question to Bob was simply asking if there was any electronic setting he could use to adjust the rear airbag to set it to a low or high pressure setting that the auto compressor would maintain. That had not been asked or answered before, except obviously in your mind. Bob had no problem understanding my question in his later response. :thumbup:
