voes with sidecar
HI ALL, I put a side car on the 80cu shovlhead lowrider ten years back and have had no probs ,i have just put a new donk in it and are running solo for a while but will go back to the chair soon maybe. I have installed a single fire ultima ignition and at the moment have a toggle switch rigged instead of a voes. I do have a voes which is set for 6 inches hg that i am going to install .Have any of you guys run a chair with the voes switch and is 6 inches hg set high enough to run ok. cheers kev

I think he meant this:
"What is the Vacuum Operated Electrical Switch (VOES)? What does it do and why is it there?
All Harley Davidson motorcycle carbureted models since the 1984 model year have used the VOES to improve throttle response, increase MPG, and meet EPA requirements for emissions.
The VOES is a motorcycle part described as a vacuum ignition retard device. That is, under low vacuum conditions the switch is open and has no effect on ignition timing. Under high vacuum, the switch closes and advances ignition timing. Essentially, the VOES is like the vacuum advance in older type automotive distributors.
The VOES is a normally open vacuum operated switch that closes under 3-5" of vacuum, are adjustable and usually require different settings for different bikes. The switch is connected to a lead from the ignition module. Under high vacuum, 3-5 inches or higher, the switch closes. A lead from the switch to ground closes a circuit in the ignition module. This circuit advances the timing of the spark. The advance increases throttle response and decrease fuel consumption and emissions.
The vacuum hose is usually connected to a port on the carburetor or intake manifold depending on motorcycle year and carburetor. There are several different VOES switches used the mounting bracket style and operating vacuum being the main differences. The FLHT models have a different vacuum range than the other models. However, just about any VOES can be adapted for use by adjusting the point at which the switch closes.
As an example...
FLT: 5.0 - 6.0 inches of mercury
FXR: 3.5 - 4.5 inches of mercury
Your vacuum gauge measures in in/Hg (inches of mercury) and/or mm/Hg (millimeters of mercury).
The point at which the switch closes.
The switches can be adjusted by removing the potted plug and adjusting the setscrew. You will need an accurate vacuum gauge and vacuum hand pump. We have been able to set the operating point as low as 2 inches and as high as 7 inches. " (courtesy--"glider", hdtalking.com)
I think this is what "donk" means:
"Hi-Risers are a type of highly customized automobile, typically an inexpensive American-built sedan modified by significantly increasing the ground clearance and adding large-diameter wheels with low-profile tires. Depending on the model and build year, autos customized in this manner can be labeled "donk," "box," or "bubble."
The term donk came from the impala symbol on any chevy impala from the year 1971 to 1976, because the symbol looked like a "donkey". "

Yeah, I guess I'm a little bored this morning.

Well Boom I hate to show this but your definition for a "Donk" is American slag, Police is Austrialian
Donk = Australian, slang) To provide a second person with a lift on a bicycle, either by carrying on the handlebar or by sharing the seat.
As far as his question goes for the VOES, you need to make sure you have your timing is spot on if you plan on using the flip switch. Advancing the timing a full 6 degrees all at once will cause detonation otherwise. The only time I remember anyone using a flip switch was when they were racing and needed the full advance at once

HI thanks for replies, sorry about the lingo guys, new donk = new engine. the old shovel ignition did not have the voes switch only evo's but with changing to the single fire there is a different ignition curve, thats why i was asking about the voes setup as the weight difference with the sidecar (chair) will make a difference and would need to be adjusted accordingly thanks kev
aussie slang::: TO DINK ,, give another person a lift on a pushie (pushbike)sitting on crossbar handlebar or rear carrier!!!!!!!!!!!!!!!!
