that's great information about the functions of the vacuum, that it not only operates the petcocks, but also works like a distributor vacuum in our older cars that had distributors. man i'm glad i came across this thread.

I am guessing I just have to have the vacuum line on the carb plugged to use this. I want to avoid the VOES system and Pingle says it is not needed with their petcocks. Anyone ever do this and cap off the VOES system?
You don't tell us what brand of motor this is, or if it comes with an ignition system. My S&S 107 came with a G carb plus ignition and doesn't use VOES, so I no longer have one. You may not need one on your bike either!

Read post # 13. The voes switch becomes an option/removed with certain aftermarket ignitions.

Default Petcock

If the voes is capped at the petcock, like a Pingel, isnt it disabled?

Thanks

The VOES is nothing more than a vacuum operated switch. If it has vacuum to it from the carb it is going to work. If you pull the vacuum line off at the carb and plug the carb, it is going to be dissabled. If you pull the vacuum line off of the tank valve and leave it open, the VOES is going to be dissabled. It can also be dissabled by cutting the wire going from the VOES to the ign. module.

It depends on which ignition module is being used. One the stock Harley module it will run pretty bad if it is dissabled. The first thing you will notice if it quits working for any reason, is your idle will be much slower.

It can make the bike run like a real bitch if the ignition uses VOES and there is a problem with it, however my bike is in yet another phase of its existence, now with an S&S motor plus their ignition and there is no VOES. I have no idea how the new motors lives without one, but it does - must be something to do with the fairies!

VOES switches the module between advance curves.

Bike switches from one curve to another depending on how hard the motor is sucking in air....high speed or high load switches curves.

Aftermarket systems can use a curve that works without VOES...so you just need to check with the manufacturer as to what their system requires.
