You need spark at the plugs, fuel and compression. If you have spark take off the air cleaner, open throttle plates and spray some fresh fuel into the inducting module, let the throttle plates close and try to start it. If it starts if is fuel related. CHANGE you plugs also even if they look good. ALSO check that nobody opened the throotel wide aqnd locked it there with the friction lock on the grip because then it wilol not start either.

Its your fuel pump if you can't hear it. And its inside your tank. Not a hard fix if you have a book that tells you how to remove it. Alot of procedures to follow to get it right. And yes it does work off a relay.

SOURCE: High Idle On Start-up.

Most fuel injected motorcycles do start up in a "fast idle" mode. Although I don't know much about fuel injection on Harleys (H-D will not tell you much about it unles you are one of their technicians), I don't think the system is equipped with an engine temp sensor. Since the crank case sensor get it's pulses from pockets cut into the outer edge of the left side flywheel half, the sensor will have oil on it.

That's a strange one. The only things I can think of suggesting are:

  • Clogged gas cap vent. The next time is starts running poorly, remove the gas cap briefly and see if things improve. If so, then the cap is not venting as it should.
  • Moisture trapped in float bowl. Drain the contents on the carburetor float bowl into a clean container and check for dirt, rust, water, or anything else that doesn't belong there.
  • Dirty fuel filter. If there is one, replace it.
  • Air leak between carb and engine. Check tightness of clamps and manifolds for cracking. WD-40 sprayed around those areas with the engine idling will help detect any leaks.
That's all I can think of. Please let me know if any of my suggestions fixed it.

What causes my 2011 dyna superglide to start hard when the engine is hot?


Your fuel injection system has to overcome the pressure of gas being in a vapor form within the injectors / fuel lines so it will take a few extra revolutions to get it to start. If there has been modifications then something else could be at fault

2007 fxd dyna superglide started running rough after the engine light turned on. makes a loud hissing noise near the fuel tank


The hissing........do this once. turn the bike to the "on" position. Dont start the bike, just turn ity so you can hear the fuel pump engage. After the pump stops, listen really close to the inside of the tank......do you hear anything, like some gas still sprinkling out inside the tank? hopefully, you are at about a half tank or less. You wont hear it with a full tank. need to know where this hissing is from, under or in the tank. you arent going crazy.........yet. :o) I'll keep an eye out for your response.

Howdy - I am interested in buying a 2000 FLHRCI R.K.C.-. This Bike has NOT been started in 7-8 years. If I purchase it, I am going to send it to a Harley Dealer for New Tires, Tune UP, Fuel Tank & fuel...


If the bike hasn't been started in that long, you may want to talk to the dealer first about the fuel injection system. Since I don't work on fuel injected engines, if I got a bike in that had been sitting for that long I'd have two concerns, the condition of the fuel delivery mechanism (carburetor in my case) and the fuel tank and fuel pump. Injected engines have a fuel pump as well.

In conjunction with all the other stuff you're talking about having done, this is going to cost a wad of money. I'm guessing a $1000 for the tires and the final drive belt in this area. If you have to start replacing throttle bodies, that could get expensive. Unless you're getting a steal on the bike, you go upside down in this deal. Talk to the Harley dealer first.

07 Street Bob. At 9000 miles, the engine mounts are loose. Bike shakes badly at low RPMs. Is this common?


You have a torn engine mount, if your bike is still under warranty get it to your dealer asap!!!!! The same thing happened to my 08 Superglide, the dealer was quick to fix it as I had no idea as to why my bike was shaking so badly. Also check that your tank mounts are tight too..
Good luck!

Oil drain plug for 08 dyna


Yes there are 3 drain plugs, each 1 is for either the engine, transmission & primary. If you are doing a scheduled oil change, change all 3. I also have an 08 Superglide, even though the book that comes with your bike says to replace transmission & primary at different intervals to the engine, I find it better to do all 3 at the same time, it may cost a little more but your bike will love you for it.

Exhaust Question


Both of the systems you mention are good systems. Best thing to do is to hear them on a bike before making a decision. The 02 sensors will handle the fuel in the mid range but the lower and upper range will still be lean. Some sort of fuel enrichment should be used for best performance and long engine life. I like the TFI and run one myself on my 07 RK. Easy install and setup and they work well in all applications except big inch motors with many mods. http://www.dobeckperformance.com/
