SOURCE: finding a 1983 harley carb with VOES tube

The original carb on a 1983 XLH was a Kehien "butterfly" type carb as opposed to the current Kehien "CV" type carb. You can find a replacement carb but you're going to look real hard for it and when you find it, it may have the same problem your carb had. So, there are a few things you can do to get around the problem.

One, you can purchase an aftermarket carb and manifold such as an S&S. The S&S Super "E" Shorty card is a good carb but it is a bit big for the 1000cc engine. If you jet it correctly and run an exhaust system with a little backpressure, it will perform well. It will also come with a nipple for your VOES switch.

Two, you can purchase an intake manifold (S&S) or modify your original manifold to provide the vacuum for your VOES. To modify your own manifold, you simply need a piece of brass tubing or a nipple that you can drill the appropiated size hole in the intake and install the nipple. If you have your old carb, measure the nipple and make one yourself. It doesn't have to be made of brass. Drill a hole in the appropiate size bolt and drill and tap your intake for the bolt to screw into it. Don't screw it in too far though and I'd install it in the flange that the carb bolts too.

Three, you can run your bike without the VOES switch. You will need to check the advanced timing on your engine. Set your ignition advanced timing to the mark on the flywheel that represents the "Front Cylinder Advanced" timing mark. This will allow your maximum advanced timing to go to the 35° maximum but no further.

There is a lot of discussion about the operation of the VOES. Depends on what you think it does, advance the timing or ****** the timing. It actually does both. Under light load conditions (high manifold vacuum) the VOES allows your ignition control unit to actually advance the maximum timing on your engine. Sometimes under these light load conditions, your engine may be running at 40° BTDC timing. But, when you open the throttle and put a load on the engine (manifold vacuum goes low) the switch tells your ignition control unit to go back to 'normal" ignition timing of 35° maximum. The purpose of doing this is two-fold. One, it gives you better fuel economy and, two, it prevents detonation or "spark knock". If you disable the VOES by disconnecting it's vacuum source and setting the maximum ignition timing to the "front cylinder advanced" mark (35°BTDC), your bike will run fine but your fuel economy may suffer slightly.

Is the clutch cable adjusted correctly, you may need to adjust the cable so that the clutch is released more fully, there will be an adjuster on either end of the clutch cable - adjust it so that the cable is tighter - but there should be a little bit of play left in the clutch - if this does not cure the problem you could have some gearbox damage,
The bike is still under warranty so take it to a harley dealers and have them look at it.

SOURCE: 2006 harley dyna charging at low speed, not at high rpms

This used to be a common problem back in the days of generators but I've not heard of this since Harley went to the alternator systems in 1970. It is unusual to say the least.

The first thing I'd do is have my battery tested. This is simply good procedure anytime you are experiencing a charging system problem.

Next, check the output of your alternator. To do this, you'll need a DVOM, digital volt ohm meter. Unplug the voltage regular at the front of your engine case close to the oil filter. Now, put your DVOM into "Voltage", "AC", Range 50 volts or better. Now, with the engine running, put one lead from the meter to one of the pins in the plug in the engine case. Put the other lead in the other pin. Rev the engine up to about 2000-2500 RPM. You should read at least 30 Volts AC. You must have the meter in the AC positon because an alternator puts out alternating current. Your regulator converts it to Direct Current voltage for the charging the battery and reduces the voltage. If you are reading thirty volts or better, I would suspect the Voltage Regulator is your problem.

I just bought a 2001 Hd sportster and noticed a disconnected vaccum line coming from behind the air filter and routed to the front of the bike. I am assuming it goes to the VOES switch but I can not locate...

Usually the VOES switch is located between the cylinders right on the top engine mount. It's a black thing with two wires and a vacuum line coming off of it. On the later models, the VOES may be mounted a bit higher. The vacuum line for the VOES and the vacuum operated petcock (if it's the original petcock) comes off the backside of the carburetor, not the air filter. If the hose goes to the backside of the air filter, it's likely something to do with the emissions system. It probably routes evaporative vapors from the fuel tank to the air filter to be run through the engine. To see what the VOES switch looks like, go to and put the information on your bike in and look under electrical section.

Good Luck

I just picked up a peacock from dudley perkins Harley. assembled the thing and screwed it into the gas tank. I hooked up the fuel line but there isnt any gas did I do something wrong?

If your petcock is a standard replacement part, you must connect the vacuum line to the backside of the petcock. There should have been a vacuum line on your old petcock unless a previous owner has changed the petcock to a manually operated one. The vacuum line comes off the backside of the carburetor and supplies vacuum to the VOES switch and the petcock.

Still even with the vacuum line connected, you won't get fuel until you turn the engine with the starter. The engine must turn to generate the vacuum to open the petcock. If you have a hand operated vacuum pump, you can use this to check the fuel flow from your petcock.

Good Luck

Keeps missing and sputtering,while riding i have to constantly adjust the enrichener

It sounds like you've got a clogged jet. It time to take the carb off, completely disassemble it, and clean every passageway in it.

You might have a vacuum leak as well. There is a vacuum line that supplies vacuum to the VOES switch, It comes off the backside of the carb, Make sure this hose is on the nipple and is not cracked anywhere. You could also have a vacuum leak at either the intake to head connections or in the carb to intake seal.

What do you set voes on a 1993 flhcu harley davidson

Most people do not set the VOES unit. They simply purchase a new one that is already set by the factory. However, since the FLHCU is a heavy bike, I'd set the VOES at about 5-5.5 inches of vacuum. If the bike spark knocks when you roll on the fuel in high gear, try taking to a bit higher setting like 6-6.5. This will cause the VOES to change state and roll back the timing sooner than the lower setting. Of course, for maximum performance (fuel mileage), you should adjust it lower until you start getting spark knock and then come back up just high enough to prevent it.

Good luck

What is the process to remove the carburetor on a 2001 Dyna Super Glide FDX. Thanks in advance.

To remove a carburetor, first turn the fuel petcock off if it has an "off" positon. Then take the air cleaner cover, air filter, and air cleaner backing plate off. Loosen the adjustment on the throttle and idle cables (the two cables). Loosen the nut on the enricher cable and allow it to come out of it's bracket. Disconnect the fuel line and the vacuum line for the VOES and the petcock. Now, rock the carb side to side and pull it out of the carburetor intake seal and guide the enricher cable out. When you replace the carb, always use a new carburetor intake seal to prevent vacuum leaks.

Good Luck

Bike starts first time on choke but soundslike misfire on front cyl sounds bad i tought maybe hydrolic tapit may not be working chap iboght it from said he rode it like this front pipe is also very blued...

You may have a vacuum leak on the intake causing the front cylinder to run lean. There is a hose that comes off the backside of the Carb and feeds vacuum to the VOES switch and the petcock. Inspect this hose and I've seen the vacuum operated petcock cause a vacuum leak several times. I'd get rid of the vacuum operated petcock. They are not very reliable. I'd go with a high quality manually operated petcock and plug the vacuum line.

Even if a hydraulic lifter was bleeding down all the way, that tappet might rattle for second or two but the would not miss.

99 dyna 88 cubic inch pops and whistles at idle ,engine noise and no fuel milage 40000 miles on engine,engine light stays on

If it'll whistle "Dixie", I'll buy it. (BG) No, if it's popping and whistling, it's probably got a vacuum leak somewhere. If it's a carbed engine, just look for an unplugged VOES vacuum line. It comes right off the backside of the carb. It might be time for a set of intake gaskets as well. If it's fuel injected, I can't help much there as I don't know a lot about those but if it's popping while idling, it's lean whether it's carbed or injected. If it's injected, you'll probably have to take it to a dealer.

Good Luck

There is a nipple on the back side of my carb and i cant seem to find where the other end of the hose hooks too?

The hose goes to the VOES (vacuum operated electric switch) and the petcock if you have a carburated engine. The purpose of the VOES is to ****** the timing on your engine. Let me explain.

When you're cruising down the road with no heavy load, the electronic ignition unit will allow the ignition timing to go above 35° total. It does this to get higher fuel economy and lower emissions. When cruising, the throttle is not very wide open and the manifold vacuum is high.

But, the moment you accelerate, you open the throttle wider and the manifold vacuum drops. When this happens, the VOES changes state. causing the electronic ignition to ****** the timing back to where it should be. The reason you want to ****** the timing when accelerating is to prevent spark knock or pinging.

So, some will say that the VOES advances the timing when the vacuum is high. Others will say it retards the timing when the vacuum goes low. You choose what you think it does.
