have an 07 ultra with 12K miles. added gas to bike this morning and now it won't start. I keep a few gallons in the garage for snow blowers, lawn mowers, and in case I need to add a few gallons to the bike or one of the cars. Sta-bil treated, gas is about 4 months old. Anyway, my bike was low (rode 2 days this week) so I added about a gallon. Started the bike up and it ran for a while, then right about the point where the just added gas kicks in, bike cuts out. tried to restart and just spins. fuel pump sounds different, perhaps it's dry spinning. thinking I got a clogged tank screen or fuel filter. plan to change out the filter and possibly drain and dump the gas.

 

You just started the bike and left it idling? For how long? Air cooled engines need airflow... aka need to be moving. Just having it sit there idling for a long period is bad for it. What octane is that gas? 91 octane or better is recommended. Maybe you have water in that gas or some dirt got into the fuel system.

 

Just a thought but check the quick disconnect where the fuel line attaches to the tank. I had mine come loose.

 

Water in the fuel or dirt. If you can drain any of the tank into a clear container its easy to see. It will seperate and the water will drop to the bottom of the container.

 

I was hoping not to go into those water.....been reading about folks with line and connection problems....I have a 2" lift kit on my tank and was wondering if/when I'd have a problem.

I started the bike to ride it to work...it ran for 30 seconds or so, then cut out.

I was thinking dirt or water...but it turned out to be water droplets.


got home from work and drained the gas. found some water droplets in it. filled with new gas. bike wouldnt start and obviously had water droplets in areas between the tank and engine. I sprayed the air filter with a little gas and the bike started with no problem...but quickly died once the filter dry out. did this about 2 more times to try to get the water droplets sucked thru the engine and on the third try, bike started right up. so basically, STA-BIL and the like fuel storage additives are worthless. I checked my gas container and found some droplets from condensation. So, this weekend, need to drain the lawn mower, snow blower, generator and pt fresh gas in them.

 

Mix a little dry gas in with the sta-bil. Won't hurt.
