- Harley-Davidson FXRT Build (Part 22 ) VOES System Explained...Back when gas restrictions were all the rage. Harley Davidson had to figure a way to beat the curve. What normally would cause most vehicles to slow down or be restricted. The VOES system was a whole different story, a specially on this Harley-Davidson FXRT. #fxr #fxrharleydavidson #harleydavidson

Thank you for letting me know about the V.O.E.S. someone told me that it wasn't necessary to have it hooked up, and i could delete it, I'm glad that I was able to find your website 👍⚡🏁
Glad I could help!
Thanks for posting this! I just found this thing on my FXR during tear down. I figured it was some kind of advance, but I’ve never heard of this system before.
Hell yeah, I was hoping it would help some one!
Great explanation on VOES system. Learned a lot.
Glad you enjoyed it!
Ty for explaining voes
Glad you like it!
Thank you! Super clear for me👍
Glad it helped!
Perfect
Thank you!
Do you know specifically if a 2000 Dyna with a twin cam came with VOES or did Harley get rid of VOES when they introduced twin cams in 1999
The VOES system was replaced by a map sensor with the twin cams.
Hi, you said in your video that the VOES is closed (short circuit) at idle and goes open (open circuit) under high vacuum. Are you sure about this? I just pulled the VOES off my 1996 Sportster Sport (during carby rebuild, had good access to pull it and check it out). I found that my VOES is open circuit with no vacuum applied and when I apply approximately 4.5 inches of mercury vacuum with my vacuum hand pump, the VOES goes short circuit. This implies that the VOES is open circuit at times of low/no vacuum and short circuit at times of high vacuum. To me, times of lower vacuum on a carby bike are wide open throttle and and times of higher are vacuum/closed throttle and partial throttle at lower rpms when lugging up a hill for example.
So, i think the VOES tells the timing to retard when it closes (goes short circuit) due to high vacuum (ie: idle/closed throttle and partial throttle at low engine rpms) to help avoid detonation in those situations.
It lets the ignition advance by opening (open circuit) at times of low vacuum (ie: wide open throttle and higher engine rpms?
Thanks for enlightening me on the voes operation. I just switched my sportster to a generic single fire adjustable ignition, would you recommend keeping the voes on this set up?. Thanks. 😁
Yes, it'll help on some MPG on that bike too
@@freebirdsgarage Thank you for the reply 👍
My 85 FXRT never came with one. It was likely removed by a previous owner. It also has an S&S super E carb and intake manifold, and a dynatek 2000i ignition. I’m doing this same job this winter to replace the base gaskets. Would you recommend buying a new VOES and putting it on, or is it not worth the trouble if you don’t already have one?
If you are running S&S I would recommend getting one back on. You won't notice a first but your MPG drops allot with out it. Plus just having that smooth throttle response towards the top end.
Do you know the part number for the male connector for that voes the one that goes out of the voes is red and the other I think it’s blue my bike didn’t had a voes because someone took it off and I need to reinstall and re wire the voes to the module
1992 fxstc softail custom
I don't but if you have a local HD dealer they can tell you and might have it stock
On the V.O.E.S. installation I'm not very good with electrical wiring. on the voes replacement 😊what wire is the positive...?
Generally speaking it’s normally the one that’s not the black wire. But you’ll need a wire diagram for your bike to confirm
Did the vacuum line rub or touch the intake??
I'm not to sure what you mean, there was no intake installed in this video?
@@freebirdsgarage yea i know , i am speaking of the existing intake manifold on you’re bike . I was just curious if the vacuum line or any part of the voes hits it or touches it. As your fxr does not have the voes bracket and is attached to the bottom of the chrome motor mount.
