So i have an 06 superglide and about a month back while riding home, i had my clutch pulled in coming up to stop light and the bike randomly died. I thought that was weird maybe my hand hit the kill switch so while still rolling up to the stop light i fired it up and went on my way. it happened one more time on the way home same situation, but i'm positive that i didn't hit the switch the second time. Each time it happened it fired up just fine. The morning following i tightened up the battery connections, checked all my fuses and put some dialectic grease on them, everything checked out fine. I rode a couple more times and everything seemed normal. fast forward to this morning i went out to start the bike up to ride to work. (finally had good weather here in Texas!) So the bike had sat for about two weeks without running. I put it on the trickle charger and its showing that the battery is good but still wont start. The bike will crank and crank and crank but it wont fire up. It doesn't seem to be a battery issue but i'm willing to bet its pretty old. Does anyone have any ideas of what it could be before i tear into the bike tomorrow? Thanks for the help fellas.

 

Crankshaft position sensor? Check to see if you have spark. If it cranks over fine then the battery isn't the problem.

 

Clean the IAC.......its in the throttle body at 12 oclock......use brake cleaner to spray in there while ignition is on and toggle the kill switch....put a shop rag in the throttle body to absorb the cleaner.......the rest will evaporate.

Another thing......when was the fuel filter replaced last?

 

Put a voltmeter onto the battery and then try to start. If the volts fall below 9, that battery is gonna need to be changed out. Have you tried starting it while still hooked up to the tender? I'd start there and then start exploring, so many options.

 

 

 

That points toward an ignition problem.

Like I said before, if the engine spins over good then you don't have a battery problem. These engines are not easy to turn over and a weak battery will show its stripes. That said, 12.2 volts resting is not all that impressive. However, once it starts the charging system should take over and a weak battery will not cause it to die.

 

Don't use brake cleaner on your intake. Either throttle body cleaner or MAF cleaner.
Also check for any holes in the internal fuel line inside the tank.

 

 

With a low amount of gas in the tank, ideally less than half a tank, remove the cap. Turn on the ignition and move the kill switch to run. If there is a hole you can usually hear it spraying against the side of the tank, or you might even be able to see it.
A fuel pressure test is the best way to do it, but without a tester this will often work.
