How to deal with your bike petcock without the need of a rebuild package

This is a pretty uncomplicated technique detailing how to restore a petcock without the need of acquiring to acquire any new parts. This technique can be nearly universally utilized to any bike petcock, and pretty usually results in a long lasting repair. In concept, this repair really should not be vital if your floats are altered thoroughly and your float needles are in very good repair and make very good seals, even so there is a large amount mistaken with this bike, and actually I just sort of want to get it running at the minute as immediately as attainable. If you have any queries about this technique, you should do not wait to get hold of me. Also, verify out all of my other backyard bike how-to video clips!

    Awesome video, I fixed my petcock with this information. My engine was filled with gas. I cleared the cylinders, and the airbox. I also changed the oil. Unfortunately, after the motor warms up, running for about one minute, it starts smoking a lot. Are the oil rings bad?

    is there any where I can get the replacement filters that fit on the petcock valve stems. I mean the one in the gas tanks . or can it still work with using only an in line fuel filter?

    Max I have an 85 Virago that has a small air hole on the backside of the petcock that is shooting out gas, I took it apart and tried to clean it but alas it still is spurting gas, any suggestions? And what is the hole for, just curious. Thanks

    I have a leaky petcock, but different symptoms. When I switch it to on, it drips from the edge of the petcock. The hose is not leaky. If I switch to reserve, it stops dripping. Thanks!

    Outstanding.  Thanks for the video.  My tank won't quit filling my air box with fuel.  I'm going to make sure I rule out the petcock as being part of the problem and this is the exact info I was looking for.

    Absolutely AMAZING breakdown of the leakage, repair and functions of the fuel petcock! Thank you SOO MUCH…you helped me pinpoint and repair the exact same leak I had in my 2002 Kawasaki Vulcan 800 Classic…and didn't have to take it to the shop! Very grateful!

    Thank you so much! I've been trying to figure for the longest why my pw80 wouldn't start. Turns out, I had a slow fuel leak just like you said and needed a new fuel petcock. Now I'm off to see how the engine held up… >_>

    How do you clean a petcock itself? Mine stopped sending fuel into the carb of my 99 yamaha warrior. I'd like to do the vinegar trick inside the tank. I'm going to add an inline fuel filter between the petcock and carb, but the gas isn't traveling from the petcock to the carb currently.

    My vacuum gasket in my fuel petcock broke on my 1979 Suzuki GS750 while on a road trip Boston – LA. I simply removed the o-ring from the vacuum actuated needle in the petcock so that fuel could flow around it while it rested permanently in the fuel-off position. Of course, you need to kink both the vacuum hose from the carb and the vacum hose from the petcock. It helped me out in a jam, and all you need is a screwdriver.

    I am working on my old Suzuki LT-F250 4 wheeler. It has been sitting for over 10 years in my basement. I have taken off the carb, air filter, and petcock off the bottom of the tank. Now my tank is wedge in the frame and I would have to remove the motor to get the tank out of the frame. Any suggestions on how to clean the tank without turning it upside down to get it clean? The 4 wheeler is too heavy to turn upside down and I do not want to remove the motor to get the tank out. Great video. I will try to take my petcock apart and clean it. Peace, Mo

    Hey Max. Thanks for the video. Quick question — the other day after returning to my bike (1992 Yamaha XJ600) a few hours after a 40 mile highway ride, the engine would not hold an idle even with the choke fully on, and eventually it stopped turning over when trying to start. It would just churn endlessly. After fiddling for a while with the bike I realized that the petcock vacuum line running from my carbs to the petcock had come attached at the petcock, most likely during the vibration/wind speed on the highway. So I reattached that line and tried starting the bike again. Again it just churned, but this time the churning started to slow down the longer I tried to start the bike. Now it will only churn once or twice before it sounds like it seizes up. Could I have flooded something by churning the engine with the petcock vacuum line unattached? I think that I turned the petcock to prime while fiddling with the bike but I can't remember exactly when I did that. 

    Any help is appreciated!

    Craziest thing happened to me trying to rebuild my petcock after watching your video. It was stuck on open (only other settings are off and res). I attempted to open it and found that someone had used grey caulking or sealer to stick the face plate and valve solidly, in the open position, to the main part of the petcock. It was all squeezed down into all the moving parts and completely solid. I had to pry off the front plate and then scrape it all off just to remove the valve and then pry it out of the back part. Was a nightmare to clean! Maybe it will work properly now!! ha ha Just thought I'd share, it made me shake my head! :)

    Great job man!  I just brought a 2001 V-Star 1100 home with a leaky petcock.  I ran what little fuel that was in Reserve out of it last night, and today I'm going to try out your method (though mine isn't vacuum operated).  Thanks, and keep up the great work!

    My husband took the tank off my virago last fall so we could get it painted, the petcock is bad this spring and now I know what to do with the rebuild kit when it comes in.  The other problem, he forgot where the pigtail goes for the low fuel light.  Unfortunately you skipped that part of the video.  If you could fill me in it would be greatly appreciated.

    BTW, I was curious about the strange name "petcock".  I mean it sounds like something your wife or girlfriend might call you, so I looked it up.  It's from French and basically means "small faucet".

    Thanks for the video. Learn alot from this. My question is when i clean my pet cock and reinstall it and hook the vacuum up and crank the bike with the fuel line off and had a can to catch the gas. When i start the bike, gas is coming out of the pet cock. when i stop the starting, gas stops, but it still drips a little for a minute then  it stops, then i let the can stay under the pet cock for 24 hrs to see if i get a drips and the can is dry.Does it drip alittle then stops ? I know you said it shouldnt drip at all after starting. Thanks

    Good vid. Im having the same problem a slight leak. Im on my third petcock (used) in 4 years and will definitely try this. I have a shutoff valve $12 on the way that i am going to hook on between the petcock and fuel filter and use it to prevent future leaks into the engine. Why cant they have an off setting anymore lol
