Harley Davidson Recent Questions, Troubleshooting Help & Support

google it or ask Harley directly you to them.

I'll bet you've got that vacuum operated petcock on your bike too. Not saying this is the problem but I've seen more problems with them than I care to mention. They're only on carburetur equipped bikes. You didn't say which you had but if you've got one, I'd check it out.

You can drain the tank and remove the petcock. Check the condition of the screen filter that is in the tank. On the backside of the petcock, the should be a small vacuum hose connected to the petcock. Take this hose and the fuel hose loose. On the backside of the petcock is square plate held on by four screws. Remove the screws and lift the plate. There is a diaphragm, a small spring, and a needle in there. Take the needle out and use compressed air to blow everything out, Rotate the fuel selector lever and make sure both the on and reserve position is clear in the petcock. Now, hold the diaphragm up to the light and stretch is slightly. Look for holes. If you find a hole, replace the diaghragm. If not, reassemble the petcock.

The vaccum hose that supplies vacuum to the petcock is very small. It comes off a large hose that supplies vacuum to the VOES switch under the top tube of the frame. The vacuum is supplied by a nipple on the backside of the carburetor. Check this hose for cracks or being unplugged.

What I suggest is that you replace the petcock with a high quality manually operated petcock. I like the Pingle petcocks. They're expensive but well worth the money. You'll have to get into the habit of turning your fuel off when you stop the bike like the "old school bikers" do. Just a precaution in the event a piece of trash gets in the needle and seat of your carb.

Now, there are other things that could be causing this. A bad gas cap for one. If the vent in your gas cap is bad, a vacuum will build up in the tank and starve the carb for fuel. you can test it in either of two ways. Loosen the cap (don't take it all the way off) and ride the bike. If the problem goes away, buy a new gas cap. Or, the shop method of testing them when you don't have time to ride the bike. Take the cap off, wipe off as much gasoline as you can, stick the threaded part in your mouth and **** and blow on it. If you can **** air and blow air through the cap, it's fine. Now, go find the Scope mouthwash or everyone will call you "Gasoline Breath" for the rest of the day.

If your bike is fuel injected, you might want to check the electric fuel pump. Other than that, I can't help you with the fuel injection. I know nothing about it as Harley is very secretive about that.

Good Luck

I'm going to give you a solution based on personal experience.

I have a 1971 FLH, 1200cc. 16" front wheel, wide glide front end. One main breaker, for all power leading from the main switch on the dash.

I would ride for exactly 8 miles, and the bike would cut off.
Nothing. Nada. Just pull over to the side of the road, and let the circuit breaker cool off. (About the length of one cigarette) Then I'm on my way again for 8 miles.

Tore the seat off, rear wheel out, dash off, headlight nacelle apart, and started checking all wiring.
Found a few breaks in some of the insulation of the wires, found where someone used tape instead of heat shrink tubing. Fixed it. Tried riding again, same thing.

Went through a few more procedures. (I am a Harley mechanic on the older ones)
Finally one day I took the headlight out again, and looked for a short. (I had narrowed it down to something to do with the headlight)

Didn't see anything apparent again. Noticed this time though, that the plastic connector to the headlight, was open on the back.
All three terminals of the headlight, that went into that plastic socket, were exposed at the back.

Having just worked on my Chevy truck, I remembered that the plastic headlight socket, is Enclosed on the back.

Went back to my bike, looked REAL close with a flashlight, and saw a 1/8th inch black mark on the triple tree. The headlight terminals are too far away to create a short?

Removed the plastic headlight socket out of my truck, put it on the Harley.

Has Never quit on me since!

[Hey, we're talking my Harley to a truck! I did get another headlight socket for the truck later!]

Question edited for clarity, full year, MAKER, model. Question moved for Cars and Trucks to correct category. The 'knocking' is worrying, but is sounds like you have a simple ignition issue. My advice is to take it to a dealer and get it on a scan tool. A CDI / timing issue is my guess. This suggests it may be the carburetor or an intake leak. https://www.google.com/search?q=1995+road+king+misfires ..

Just make em tight and dont strip em! Usally parts like this, that are not related to some real mechanical aspect of the vehicle dont have torque specs Motorcycles tend to give more torque specs than automobiles but, since this thing just hold some guages and what not, it just needs to stay on there. I don't have a Harley but, I've had dirt bikes all my life, and I have a honda xrl650 which I ride on the street now and the torque specs on the suspension and wheel components are the most important, to me anyway. Good Luck!
