That's a pretty good thought Edward. I just got back from a ride to Alaska where the gas was sometimes "questionable". I will check out the filter/tank. Thanks.

 

Try rotating the fuel line at the fuel tank (where it fits in the connector) then cycle the fuel pump then crank and see if it starts. If not, then check for spark by buying a $5 inline spark tester at Harbor Freight. Put it between the plug and wire and see if you get a dim orange glow while cranking. If you have spark then you know for sure you are in the fuel line to start looking. The fuel line fitting at the tank end sometimes are an issue.

 

I read others saying that if you see fuel being splashed as the fuel pump pressurizes the system, then you have a hole in the fuel line. That spraying is from the pressure regulator, not necessarily from a hole in the fuel line. It might be, or it might NOT be. Either way, replace the fuel filter, then try it. You might well be pleasantly surprised. That happened to me, I found what I found, replaced the filter, and all was well in the world. The suspect hoses were actually in perfect condition. They now have over 115,000 miles on them. Of course, your results may vary.

 

Going back to the bottom of the tank fuel line quick disconnect, if you have never played with that before, you probably don't know that there is an anti-drain valve built in. When the fuel line is disconnected, the anti drain valve closes off fuel flow and only a few drops of fuel will escape. For some unknown reason, occasionally that assembly will stop passing fuel creating your symptoms. Simply disconnecting the fuel line fitting and then reconnecting usually restores fuel flow. It is quick, easy and FREE . If that doesn't get you going, then go for the more complicated fixes.

 

Also harmless fun to disconnect your riding buddies tank connection and watch them freak out when their bike wont start. I say harmless if they are the type to laugh when a practical joke is played on them. If they are the type to chase you down and beat the crap out of you, maybe not so harmless.

He's right though. Only takes seconds and cant hurt to try it.

 

Update.....thanks to Guntoter and btsom the problem is fixed ! I undid the disconnect, plugged it back in and the bike fired right up. I will finish my 3 hole oil change and then see if the O2 warnings are still there. I do want to change the gas filter but will have to order the tool to take it out. Thanks everyone for the quick and knowledgeable responses.

 

If you are talking about the big ring on top of the tank, no special tool required. A big screwdriver and a hammer will work. Put the screw driver on one of the tabs and tap it until it moves a little, then go to the other side of the ring and tap a little until it moves again. Go back and forth from side to side and it will come off. Just be very careful the screwdriver doesn't come off the tab and scrape down your tank. Put it back on the same way.

 

Thanks Edward. I was thinking about that solution yesterday. I will give it a go.

 

EdwardK….used the screw driver method like you suggested and it was very easy to do. fresh filter out in and good to go. Thank you.
