pingel petcock needs vaccum?

Ok, what zl is this for - it's not listed in your profile? Anyway, have you tried removing the inline filter completely and running on prime just to see if there is any change? Just an idea that might be easy to try before tearing everything apart. Some inline filters may be too restrictive. Later.

It is for a 1000, and i can try it without the filter, its an idea
 
#1 and #4 go to a plastic vacuum T that connects to the air valve...cap (with a mama kaw part) and throw that air valve crap away. You also have to cap the hole in the air box, most use a nickel....This is for non-emission application. This might work on emission, although don't hold it against me.

The air valve removal, is in the modification part of this forum I believe....Good luck with this...I hope that some "expert" gets this running for ya. I'm no expert, by far. but last summer, I removed the air valve and the #1 and #4 hoses that came off the carb, went to an automotive type T and then a hose went to the air valve...this again, was on a 900, so it might be different, I'm sure I'll get shot full of holes if I'm wrong. But I am just trying to help.
 
Ok, for a 1000, if you are interested in removing the emissions stuff read the link below - it's the same for the 900 and 1000 - only difference would be if you have a california bike with the extra emissions stuff - no big deal, same procedure, just more to remove. Later.

Jarney...I read someplace in this thread, that he was asking about where the #1 and #4 tubes went, that's all.

If you pull your tank and petcock, go ahead and open up the diaphram cover on the back that has the four screws holding it on. Remove the four screws and raise the cover straight up and make sure the spring is right.....you'll see how it should go. Did it not work right since receiving it or is this something that's happened since you got it back? I'd be glad to go back over it if you can't get it to 'act right'! :goodluck:
 
Make sure that you don't have any kinks in the fuel line feeding the carbs. It doesn't take much to slow the flow!
 
If the petcock is repaired correctly from markus (should be) then you should not need the extra filter Just the orientation of the filter(extra) could cause issues with flow. They can air lock. It DOES NOT MATTER which vacuum line goes to the front or to the petcock...vacuum is vacuum...It does not matter which carb it comes from. If it was me I would cap all the ports but one and run that one to the petcock. on second tought I would do what I did to both my ZL's and put pingels on...End of story...All four og my ports are capped and Air suction valve and plumbing removed...

It has been the same problem, your petcock is the 3rd one i have tried with the same problem so i don't think it is the petcock. The tank is cream coated, and i am running pods.

I will try to remove the inline filter and see if that helps. I want to be sure tho that i can run the vacuum from the #2 carb and just cap the rest, without running anything to an exhaust valve..
 
As another hunch, the vent lines between carbs 1/2 and 3/4, where are they routed?

Good question here as well...On both my ZL's I had no tubing attached to the bowl vents, I just had the ports pointed down and back. Hopefully these ports are not connected to a vacuum source in this situation...

Or if they are connected to tubing, the tubing is not restricted...
 
One thing i am getting at when running pods you can get weird wind dynamics around the carbs. Last year i took mine for a ride and didn't have the tank vent hose or the bowl vent hoses connected. After a few minutes at freeway speed, it would start to bog like it was running out of gas and i could see bubbles in the fuel line. Once i got home i put tubing on all the vent lines and routed them the seat. Have not had an issue since.

When I get my bike ready for the spring, I need to pull my carbs and move the notch on my needles. I was undecided at the time I put the carbs back together as to what I was doing with the exhaust. I set them up as a guess for pods and stock cans. I get a slight hesitation just off idle on a hard throttle twist. When the weather was a bit warmer (60) it was not as bad, but at 40 it got worse. I think my needles are lean. Anyway I had noticed running my 1K a couple years ago when I ran in a strong crosswind I would get what you describe sort of (stock air box at the time, but my bowl vents have never had hoses on them...Could be the reason...
 
It was driving me crazy, I knew other people had run them open. In all honesty I dont know if it was the bowl vents being open or the tank vent not having a line connected. One or the other, but once I hooked up some extra fuel line and routed it under the seat, it's been fine.

Also to the OP, what size fuel line are you running? Should be 5/16"
 
The carbs are jetted for pods, and i have not changed the tubing other than adding a second vacuum tied to the #2carb to the petcock. Ill have to pull my tank and look at how else it is set up by the po. The bogging down at freeway speeds is primarily what it does so maybe its that. Its sunny in ohio today so i just took off the xtra filter and took it out, ill let you guys know how it goes!

I just got the fuel line that fit the nipples, pretty sure it was 5/16. Not hard to push on, and then clamped down.
 
No problems yet, took it out on the highway. Maybe the filter was the problem after all.. It was a large capacity, and yes i had it installed the correct direction. I hope i can ride this spring, im so excited!

Even when facing the correct way, they can cavitate and cause a starvation of fuel. The thing to watch out for is with a stock petcock, you can get the figure 8 disease. With the rebuilt petcock from Markus, this should be solved. The screen in the petcock should be finer than an in-line filter (it will filter better). The stock petcocks have an oval shape and they are plastic. It nests in the aluminum body of the housing. The plastic malforms and pulls in at the center and will cause the normal oval to resemble a figure 8. When this happens it creates a gap that allows gas go get out of the tank unfiltered and can cause havoc inside the carbs. The pingel solves this by using a different system and no plastic to malform.

Hope this solved the problem and now you can ride like the wind...:headbang:
 
My offer still stands, so once we get through the cold and snow, you need to ride it over to my son's, since he is 2 miles from OSU and we can help you out with any questions/concerns you might have.
 
Okay, i have been riding successfully with the extra filter removed, with the 2 vaccum lines joined to the petcock, except the past few rides it started to bog down and backfire, it sounded like it was flooding!
So i changed back to the single vacuum from the #2 carb and capped the others, and now it is running like its gas starved again, it shuts down on run so no gas flows, and barely got me to work today on prime. Wtf?
Is there anyone in ohio who would help me fix this? Maybe i need to open up the engine and adjust valves.. I have never done this and dont know where to start.. I really want to keep this bike, its great when it runs..
