Tech answer in Motorcycle Cruiser Mag.

[SlowRoad]

  May want to check out the April issue of the mag as I learned something new about the Valkyrie. A reader wrote in about having problems with his Valkyrie shutting off on him like it's running out of gas. I have been dealing with a similar problem for over a year now, but never knew that I needed to check the "fuel pump."    And all this time, I didn't think the Valk had a fuel pump.    Guess I should have checked somewhere else rather than the VRCC board and the service manuals to try and track down my problem . 
  I would think that these guys would do at least a little research before  answering a question in a national mag. In his defense, he did suggest some other legitimate checks, but I had to chuckle when I read that the fuel pump often causes this problem.

and usually only happens when the roads are wet but I have been able to trace mine to the vent tube getting plugged. Never would have thought to check the fuel pump .... that's right next to the henway .... isn't it?

Friend of mine had the same problem on the 'new to him' Standard he purchased from the dealer after they did their big inspection and said it was in perfect condition.  Kept dying on him as well... ended up being a pinched vent tube from the fuel tank.  Open up the tank when it stops, if it goes woooooosh, then you've got a stopped up/pinched vent tube.

I've narrowed mine down to a venting problem, but can't find where the problem is. It only happens when the temps are about 70 degrees or above. I changed out the vent line last summer and left the T inline. I have checked for kinks and found none. When I did my maintenance a few weeks ago, I ran a wire thru the vent tube in the tank and found no blockage. I have a penny under the gas cap seal and it runs fine as long as its there, but it has done it once already this spring without the penny after I ran the wire thru the vent tube. Put the penny back in and it has done fine.  It's very agitating to think that it is fixed, then after several rides it does it again. I have quit trying to track it down. I am sure I will find something one of these days that is very simple, but it's not worth the headache to try and track it down anymore.

It doesn't take much for it to become kinked, try this as it has always worked for me. Before you install the tank, take a little lube ond run it where the tube drops down. Once you install the tank, reach under the swingarm and grab ahold of the tube from below and give it a pull, it should drop down a little more and straighten out. If this does the trick (which it should) take a marker and mark it against the frame as a reference point for next time.

How 'bout rerouting the tube? Mine was very tightly wedged between 2 parts I couldn't see but could hardly move the tube it was wedged so tight. I've been having the same problem since rebuilding petcock. Still not sure it's a venting problem but it sure as he?? acts like one. I need to try the penny trick to verify it is a venting problem.

Same "tech" would probably attribute hard starting & a high RPM miss to closed ignition points, a faulty condensor, or dirty fuel injectors.

it has to be something that happens after removing the tank, same thing happened to me after replacing the air filter. always dies at just the wrong time. it can be dangerous.

I vote for all three at once.

Have you tried the vent 'the other way'? What I mean is have you blew air up the little vent nipple into the tank? You may have dirt stuck up there. I've removed my tank and have swished gas around to have it come out the vent hole. Give it a shot. Not sure I'd do it with a full tank but do it with some in it and get it to burp.
