recently had a close call with a bad diaphragm on the oem petcock. number 6 was full of gas but i got off the starter soon as i heard the dreaded "clunk" ??? used a k&l rebuild kit on the petcock and replaced the vaccuum line to #6 cyl. rode 100 miles this past weekend and now fuel is leaking from the main line. i'm gonna replace that 6 or so inch piece of fuel line today....but still, it shouldnt be leaking at all. a working diaphragm should prevent that.....what gives??  shutoff position on the petcock no longer works. its always on. i guess i should just install an electric shutoff or manual fuel shutoff. any leads/links on an inexpensive electric shutoff or manual fuel shutoff for a 98 standard????? |

My advise is to get rid of that POS OEM petcock. A pingel will solve all diaphram problems as the manual version has no diaphrams.........piece of mind as long as you remember to shut it off. But if you are going to add an electric cut off then youre golden......still get rid of that petcock! |

Agreed, Pingel. Maybe your guts are put in wrong.

I have a Pingle in route to my house due to the OEM petcock, deciding to take a sheet as we loaded MGM up for a trip to Minnesota.
When we got there it had quit leaking, but Pingle on way just in case the bastard would start in again.
I figure I have been lucky. 242K + and no problems before. So, it was due to be changed out.

did some info searching. looks like the dan-marc electric shutoff is the way to go!! PLUS.........its inexpensive  i'll just keep the oem petcock in place since its freeflowing anyways and rely on the electric shutoff. |

I certainly agree with the change to the Pingle.. Just use a mental pre-flight/post-flight checklist,, right hand to the key/ left hand to the petcock..

The nice thing about a Pingle is you never have to remember to turn it on.
The only thing to remember is to turn it off.
After a while it becomes automatic, turning it off - that is!
The bike will remind you, if you forgot to turn it on.

ordered the electric shutoff.
when i go to install it...looks like i'll need to remove the air cleaner box as well to get full access.
must i remove all six intake boots in order to remove this box???
is there a thread dealing with the box removal?

once i get the box out......i wonder if this would be a good time to perform a desmog  bike is still completely stock and looking at the pictures....there seems to be a lot of crap that can be removed during a desmog....allowing for more airflow through that tunnel. down here in louisiana its over 90 degrees 9 months out of the year and i need all the cooling i can get.  |

Believe me, the air box and all of its six tubes must come out to get down to the fuel line. Now is also a good time to do a desmog or replace all the vaccume hoses, which ever appeals to you. I have always done the desmog, but that is just me. I have done the desmog several times and added the Dan-marc to my I/S. A hide-away switch on the Dan-marc is good insurance against a thief getting more than half a mile on your bike. I used the Dan-marc with the built in filter, but it is a little larger and harder to fit into the tight space down there. Also, I powered the Dan-marc by connecting to the black/white wire on top of the closest ignition coil. No problems...Jim   |

Since its on top (subject) I'm +1ing the pingle, with the carbs hanging over the cylinders, why have to mess with extra vacume line, diaphram wear, seating ball properly/wear, and, if it does not flow enough fuel, it opens up a whole other can of worms. I was also thinking it cant be to good for the thin diaphram to have to run any heavily treated fuel from sitting to long. Pingle 1311 CHYes I agree, I know when I shut my fuel off,, How do you know the electric valve is working, except for the bike getting gas when the key is on. Is there an off indicator on the electric valve? Seems like to much gizzmooligy for such a simple task. Just as the oem valve. http://pingelonline.com/powerflo.htmLOL Exactly,,,see Rickyd post below... |

I don't get it - how fuel can get down the vacuum line to #6 without you having fixed the leak first. I have heard stories of the vacuum diaphram failing in the petcock, and fuel passing through the cracked diaphram, down the vacuum line to #6 and hydrolocking it. Even the Dan-Marc won't stop that scenario. Looking at GR's diagram (linked below) both the fuel valve diaphram and the vacuum diaphram have to fail for there to be a path for the fuel to pass down the vacuum line - and there is a vent between them, so if the fuel diaphram cracks, fuel will leak out the vent and you will know you have a failure from the leak. If the vacuum diaphram cracks, you will also know it because the bike won't run with the vacuum diaphram remaining closed due to the leak. Is there an error in GR's diagram? The mod described by Gryphon Rider to change the OEM petcock to full manual, and eliminate the vacuum function - and close off the vacuum line is here: http://www.valkyrieforum.com/bbs/index.php?topic=37577.0 I wrote up installing the Dan-Marc here: http://www.horseapple.com/Valkyrie/Tech_Tips/Fuel_Shutoff/fuel_shutoff.html |

If you go to the trouble of installing an electric valve and then installing a hidden switch, I don't get it!!!
I mean where is the difference between that and just installing a Pingle.
Seems like a lot of unnecessary trouble and expense to get to the same point.
I personally think the Pingle would be a whole lot more reliable. Talking about the manual one here!
And who the heck wants to steal a Valkyrie anyway?

LOL ......i'm gonna block off the #6 vaccuum line, remove the diaphragm from the oem petcock so that its free-flowing. If theres a diaphragm in the selector side of the petcock, its definitely bad because it won't shut off the fuel.
I'm gonna try to install the dan-marc without having to remove the airbox, but i think its gonna have to come off.
I've read the threads about desmog and if i DO have to remove the airbox, i will rip out all that smog crap thats under there. Aside from buying the blank plates, i'll just block off the metal lines with JB weld or something.

Pingle, Pingle, Pingle. Well let's see, Ricky-D. $25 for a Dan-marc & $100+ for a pingle, which answers the "extra expense" assertion. I personally don't like the looks of the thing, even though many say that they work well. So will a $20 switch from JC Whitney that looks like crap. As for the hidden electrical switch on the Dan-marc, even the village idiot can see the theft prevention value of such an arrangement. I am not here to tell someone else what to do or to criticize what someone else has done. I only provide information as to what I have done, how I did it, and what worked for me. What someone else does to their own bike is of no concern to me...Jim  |
