Fat momma not running well, need some help. 2000 Tour

[Lazy]

Got out for a ride today and she did not run well. Had to put charger on it to help get her started. The battery was not dead but too weak to get her started. I rode a few miles and she started dropping cylinders like running out of gas. I was headed to fill up any way, I knew it was really low. Got gassed up and rode another 10 miles or so and started the same thing, acts like it is not getting enough gas. I pulled of because I thought it was gonna completely quit. I shut it off while I was scratching my head trying to decide what was wrong. Started her back up and running good, ride another 7-10 miles and starts the same thing.
I have done a fair amount of work to it this winter, took the carbs off and had them cleaned, new pingel petcock, dan marc electric fuel valve with filter, custom built plug wires, desmogged, and some more stuff that would not pertain to this issue, I don't think.
While coming home I opened the gas lid to rule out the tank breather tube, same problem. Got back home and replaced the interstate icm with the original, still same problem. When it is running badly if I turn the choke on the engine will almost die. Also, I made sure to keep the fuel lines running down hill from the petcock. Still it is full of gas. PLease if you have any ideas.

A few people have had problems with fuel delivery through the danmark AND a fuel filter. I don't know how they fixed it. Should be able to find it by doing a search on the tech board

[Joevalk]

Kinked fuel line possibly. I can relieve you of your problems, just send the bike to me. I'll even pay for shipping

[pancho]

Certainly sounds like a fuel delivery problem, I would center my attention to that area,, probably remove the fuel filter to start with.

[Lazy]

I am using the model 152 with the filter as part of the fuel valve. I forgot to say that in the orihinal post.

Insure the fuel line is always going down. After adding on the filter and Dan Marc, you might have it going up hill at some point.

Since you have taken it all apart, I was thinking of a kinked vent line, check that too, but usually it doesn't happen that quickly. You could open the fill cap and stick something under it, so it doesn't seal, like a coffee stir stick.

[R J]

The Dan Marc has to flow down.    It can not have a rise of any kind in it, or you will have the problem you are referring to.

You apparently had the tank off while adding the Dan Marc.    Did you change the petcock to a Pingle?    Just for grins, recheck that vaccum line.

Go over everything you did during the modifications period.

That is always the best place to start on problems.    What id ya play with last.

[Lazy]

I rode it some with the fuel lid open to test for the vent line with same problem. New pingel installed and the only rise in the fuel line is where it comes OUT of the dan marc going to each carb bank. The rise there looks much like original.
Do I need to get a Dan Marc with no filter? Is that the problem? I thought I was doing a good thing by adding the electric valve with the filter but maybe not.....

[signart]

Put it back the way it was made... ride.

[lljjmm]

For starters - your vacuum lines,  may appear good but may not be, especially if you have been moving them around. (From experience). They may look perfect but.......

[longtom]

may not seem technically feasible , but have heard of Valks not running well due to battery ,even if it did start it

Get rid of that rise in the gas line.....   Should fix your problem.

Don't bother asking how I know, I fought this same problem for a week way back when i 1st converted MGM to Pingle and Dan Marc.

Since you mentioned the battery being low I would also check the alternator output. Why was the battery almost dead? Low voltage may be the problem.

[Lazy]

Fatty has been run very little since November so the weak battery was really no big surprise. I charged it a few minutes then started her up with the charger still connected and after riding awhile she starts fine. I have removed the electric fuel valve to redo all that for more down flow, I hope.

We shall see what happens next.

Thanks for all the response!

[Ricky-D]

You ought to leave that electric valve "off".

It causes more problems than it fixes, if it can even do that!

I don't think anyone, regardless of age, cannot learn to

shut off the gas.

And if someone were that absent minded, well they probably

ought not to be riding a motorcycle anymore.

Jus sayin'

Ricky D, I never had to shut off the gas on anything I have ever owned with 2 exceptions.      My 1944 Harley ServiCar and the 1937 Indian 4 of dad's I rode.


I fix, replace or whatever so long and then I put a real fix on it.

That is why MGM has a Dan Marv valve.

You come and try to remove it, you will leave finger less.   Trust me.

I've had my valve for quite awhile and as of this posting, have not had a problem with it on the 2 wheels, or on the current 3 wheels.   And it has been topped out at a dollor and a quarter on 2 wheels,  about a dollar and a nickle with the 3 wheels.

[3W-lonerider]

Ricky, iv'e had an electric valve on mine for 10 years now. have never had a problem with it.
but i'm truly amazed that we all don't just stop helping people and just let you chime in and cure every ones problem. you seem to know it all.
legend in your own mind. half the advise you give i give you credit because it was either well thought out or you knew what you were talking about. the other half i think your talking out your ass because you hav'nt got a clue. if the powers that be decide to remove this post then so be it..i call it like i see it.

[Lazy]

Hey RJ, do you remember which valve you are using? Is it the 111 without the filter?
Thanks for the help!

We'll I took the dan Marc off and connected it to the fuel tank with all of it off the bike. The dan Marc valve (with filter) is just not flowing enough gas. I have ordered a new valve without the filter and we will see what happens next.

Thanks for all the help!

[Lazy]

Fat momma is all better now. I put the model 111 shut off valve on and plenty of fuel flowing now.

Thanks for the help!

Good to know ! Thanks for posting the resolution.

[RDROGUE #0128]

Dan Marc fuel valve with filter is probably 1.5 inches longer than 111 model and does not allow for much room at connection to petcock.
If there is any excess fuel line it will easily get enough kink in it to cause the problem described, especially when fuel line gets heated up.
I don't believe the valve itself did not have enough flow.   

[RDROGUE #0128]

Good thread on the subject.....

Hey Lazy glad you got your bike runnig well again. I got the Dan Marc 111 on both my Valks and have not had a hint of problem. The only thing I've noticed is that both bikes require going to reserve sooner then when they were OEM. I need to go to reserve around 140 miles with the Dan Marc in place while a stock configuration gave me around 160 miles before reserve. No biggie really!

She is running great now. The dan marc with the filter just would not flow enough gas. I even tried connecting the valve to the tank with the tank off the bike. just not enough gas flow. the 111 valve is flowing plenty of gas and got the "riding a Valkyrie " smile back on my face.

Thanks for all the replies!

[RDROGUE #0128]

I installed the same 152 filtered model valve and am experiencing the same issue as you describe.

Wonder if the filter section can be removed so I can still use this valve?

[salty1]

I believe it can.?

[Skinhead]

If not, it can be drilled out.

[John Schmidt]

I also have been running the 111 model for most of the eleven plus years I've had the bike with nary a problem. I have a Pingel manual petcock, and just off that is an inline filter, next is the DanMarc.

As for comments re. remembering to shut off the fuel, I think it was a bit overboard. Insulting may be a better term since people do make mistakes. Apparently some don't....ever!

I tried removing the filter from the valve and connecting to the tank with it off the bike and the flow was still far too weak. I considered drilling but chose not to because I was afraid there would metal shavings left in there somewhere that I couldn't get out so, I got the 111 and cured the problem.

Been there, done that, got the t-shirt, washed the car with it....
