Anytime you have an electrical problem, the first place to start is the battery. Motorcycles are notoriously hard on batteries due to vibration. Remove the battery and take it to an automotive parts store and ask them to load test it. Judging from what you said your bike did, I'd be surprised if they didn't tell you the battery is bad. It sounds like the battery suffered and internal short that basically killed all the power to your bike or at least dropped it down to between two and eight volts. I think this is what is wrong with your bike. I hope this helps. Good Luck, Steve

Dies while decellerating


Check your oil. It is possible that your car has a low oil pressure shutoff and when cresting the top of the hill, the oil goes to the back of the oil pan, telling the sensor it has no oil and shutting down the car before any damage occurs.

Motor turns over normally when i turn the key but will not catch and run


When this happens have a can of spray starting fluid on hand, spray it into the engine air intake, if the engine starts you may have a failing electric fuel pump

Engine quits while cruising ( but idles fine & revs up ok while stopped)


No Codes?

Quites only when hot & driven 20 miles?

Your the original owner-- but do not know what
has been worked on in 6 years. You & I would have
real serious issues face to face

I hope you know that for the last 25 years a tune-up
is only spark plugs. No tune-ups-- just shops living in the
past with the nonsense of advertising to get you in there

I assume since your in love with dealers & I hate them- that
you have had nothing tested or gone for a ride with a scan tool
to check data. You need to be part of the process or your
going to get hosed at these places

Worst part is they don't fix anything

Could be the egr valve or system item
Could be coils breaking done as well as egr
Could be fuel issues

But shutting off,not the usually senerio

When pressing on the gas pedal the car feels like it wants to slow down, in fact it does then picks back up speed, expecially when going up any hill, also will start it and it will stop running on its own...


This can be caused by deposits on the back of the engine intake valves and dirty fuel injectors, another culprit is the throttle valve being sludged up. I suggest you try cleaning the throttle valve and idle speed control valve by following the instructions below. If this fails to help then you should get the fuel injectors professionally cleaned (not the junk you put in the fuel tank, a waste of money).

Throttle Body Cleaning on vehicles without electronic throttle control (most 2000 and down)

You can in most cases repair this slow speed stall or unstable idle by cleaning the engine throttle valve and the idle speed control valve using a product called CRC Spray Throttle valve cleaner. Spray the cleaner into the air intake of the engine with the hose removed from the throttle body, the engine will try to stall so hold up the idle speed manually. Once you have used up about 1/2 can of the cleaner stall the engine out while spraying and turn the key off, disconnect the negative battery cable for 5 minutes and then reconnect and drive the car for a about 25 miles of varied driving modes. If this doesn't cure the problem you may need the fuel injectors professionally cleaned by the dealer service dept.

Sounds like the ignition switch is failing. Tires come in different composites for short or longer life. Cheaper tires, poor alignment and driving styles can cause early wear where as high mileage tires and easy driving with a good 4 wheel alignment can last sometimes upwards of 100,000 miles. service manuals are available online or at you local auto parts store for around $25.

Got a 2006 super glide, the sun of gun without warning will give a little backfire and the whole electrical system goes dead, Note: with key off the needle on the speedo will continuously pulse; turn key...


first thing i think i would look at would be the wiring connections for the battery. CHECK AT BATTERY AND THE OPPOSITE ENDS OF EACH CABLE. if these are good, maybe check your charging system. sounds like it could possibly be failing. start bike and allow warmup. disconnect battery ground cable and see if it still runs. if it cuts off immediately, your charging system has failed and you'll need to determine the cause and correction.

Backfire after shutoff


With the key off and the engine "running down", the idle circuit fuel is still going to into each cylinder then out the exhaust. A hot spot in the exhaust can ignite the unburned fuel creating an explosion, ( backfire ). Let the engine run down to an idle THEN turn the key off.
