Same thing going on with my DRZ. The carbs and petcocks suck on Suzuki. So glad you posted this about the Raptor. It's exactly what I need. Had a Raptor too great quad.
I got a good deal on an 03 Eiger but started to worry when it kept dying in the "run" position. So glad to see that it's a cheap and easy fix! Thank you.
i mite owe my mate an apoligy i acused him of rolling my quad and he swears he didnt lol this video looks good for him coz 2x mechanics said its been rolled.cheers
I replaced mine as he did and it ran just fine. However, keep in mind that it's now grvity flow and if you don't turn petcock to off the gas head pressure could keep it flowing through your carb into the airbox. I ordered an aftermarket carb for mine and it was too large of diameter to fit. I ended up finding a good used one that's working and fit like it should because it was OEM. Good Luck
Thanks for the vid. Mine failed on me just the other day and it took me quite a while to figure out what was wrong. I just ordered the Yamaha one from Amazon for $15 bucks! Thanks again.
This will absolutely work, but remember, once you change the "vacuum" petcock to a "manual" petcock, you are now depending solely on the needle valve in the carburetor to stop the flow of gas. Be sure to cut the petcock off when the engine is not running. I changed my Suzuki Vinson 500 over to a manual petcock and still had the same problem. I ended up having to change the needle valve as well, to stop the gas from filling up the cylinder. Now when I am riding, even if I stop for a few minutes, I cut the petcock off. (Side note) Regardless of the reason, if you ever have gas to enter your cylinder(s), change the oil asap before trying to run the engine. The gas that enters the cylinder(s) will run down into the crankcase and can create a catastrophic engine failure........
Huge thank you! I would have never looked beyond a clean petcock. I'm still plugged up in test mode while I await delivery of the new petcock, however it has never run better!
Good information! Your video is the only one that explained how the diaphragm failure not only fails but starts to suck gas which explains a lot. One question though, couldn’t you just plug the vacuum hose and set the valve to prime and be good to go. Still need to change oil etc.
Hello It is good to have a way to shut off the fuel. If you haul it on a trailer the bouncing of the float in the carb can cause flooding and if the needle valve in the carb let’s gas by it causes flooding. I’ve just always shut it off when not riding
This is good to know, I have a 05 Suzuki Eiger and have been worried about the OEM petcock failing. I'm going to replace it now with the Yamaha 660 Raptor petcock,thanks for the heads up video.
Mr DMan, I have a 2005 vinson 500. It has the identical carb and petcock, I did the exact same repair as seen in your video, plus I put a rebuild kit in the carb. No holes in float and float needle valve seals air tight. Yet after all that, I am still getting gas freely flowing into air filter box and filling my engine. I can't explain it.
Hello When you say you did the repair to the petcock, did you put in a manual one? If so then the only thing I could think is the float and needle is still letting gas in.
@@dmanshowto8193 Yes sir I got a petcock for a Yamaha but not one for a Raptor, the only difference was mine had a smaller tube size outlet. After the carburetor rebuild and changing the petcock it ran well but then all the sudden it acted like it was flooding out. Left it alone for a few days, only to come back and find my air filter box full of gas again, as well as the crank case. Took the carburetor off again to check the float assembly. No sign of gas in the float itself, the assembly moves freely, even while the carburetor is assembled, and I can NOT blow air through the gas inlet while the carburetor is inverted // the float assembly and needle seals appropriately by gravity alone. I agree with you! I just don't understand how gas can be getting by the float needle with it working on the bench so well. It's frustrating. I thank you Sir Your video was great information. I'm thinking of looking at an aftermarket carburetor.
I have an 05 eiger, I have gas in my air box, I just replaced the petcock from vacuum to manual. I had an overheating issue header would glow red, I cleaned, and rejetted carb, from 122main 38pilot to now a 130 main and 40 pilot, fuel screw out 1 turn, I also put a new needle valve and bowl gasket in the carb. I also readjusted the valves. Now I’m having this issue with gas in my airbox, and quad is hard to start/not starting, what could be wrong?
Just guessing, but I think the float is bad. Not lifting enough to close the needle or not adjusted low enough to stop the gas, or maybe your new needle and seat? Not much help, sorry
yup did that mod when i first got on my 03 eiger about 3 years ago one of the best things i did just got into the habit of making sure i turn gas off just in case
It’s possible if the petcock is letting gas into the bowl and the needle isn’t seating good it could flood. That’s why I like the manual ones so I can turn it off. Especially if I am hauling them because of the bouncing.
sweet .....had the same problem. Suzuki should recall that POS. Cost me 2 il changes and the cylinder was full when I tried to start it which could damage crank piston the ENGINE...what a POS. Thanks for the fix.
Good video. I am about to swap out the original “vacume” valve for a manual valve. Question. Do you have to turn the valve to “off” every time you turn the bike off? If so, why?
Christian D. You should now treat it like all the other bikes that are a manual valve. If your not riding it for awhile or transporting it make sure to turn it off. All carbs have a bowl and float with a needle that stops the gas but a bad needle or bad adjusted float can let gas by. It’s best to just get used to turning it off when done riding
It’s not a good idea to leave gas always going to the carb. If the needle or float in the gas bulb fails then your risking flooding the engine and possible damage. I would move the petcock off of prime until you get a new one
Thanks for the vid. Will it work on any carb bike? Why not simply turn it to prime and clog that vacuum line? What position should I turn the new petcock to? TY
Poor design or choice of fuel delivery by Suzuki. I replaced mine with a gravity flow petcock for a Yamaha Blaster for a fraction of what OEM replacement would be. Thanks for sharing. Now I have clicking from the relay under the seat when hitting the start button. Not sure if it's the starter brushes bad or the actual relay itself. I'm not quite sure how to test the relay yet? Anyone reading any help is appreciated. T/Y
I think I have the same problem on my Kawasaki motorcycle. Except the hose coming out the bottom of the airbox is split open. But gas soaked in my airbox
Hello, i have the same problem! 07 Suzuki vinson. I replaced the valve with a OEM one , Still have the same problem. Recked and found out i have no vacuum from the carb! I will fix. I plan on installing a bypass vacuum valve. I will use a tire valve stem, a metal one with a nut and install a hole between the carb and eng in the intake hose. after i remove the shradder valve. I will reroute my vacuum hose over to my new vacuum port! i believe this will correct the problem.
Back in july of 2023 the factory petcock died on my 2000 suzuki king quad 300 4x4 ending my day of riding and i had to be towed 2 miles out of the woods 🪵

Many thanks for the video. 2 1/4 pints of petrol in the air box. Problem sorted and the quad runs sweet again.
Thanks for the video I spend this 500 at my local shop they couldn't figure it out this video is great help
Thank you so much for putting this on youtube. My husband couldn't figure it out and I found your video and it worked. Thanks!

Just get in the habit of turning it off
This was the best explanation thanks..

You mean it’ll work like every other f ing quad ever built. That’s crazy.
Huge thank you! I would have never looked beyond a clean petcock. I'm still plugged up in test mode while I await delivery of the new petcock, however it has never run better!
Awesome! Thanks for sharing, will b doing this mod on my newly purchased used eiger.
Thank you for the video, getting my 06' Eiger ready, and doing this mod.
Wow! My Kawi Concourse runs, but has gas POURING out of the air box. I sure hope this the problem, don't wanna pull the carbs! Thanks.

It is good to have a way to shut off the fuel. If you haul it on a trailer the bouncing of the float in the carb can cause flooding and if the needle valve in the carb let’s gas by it causes flooding. I’ve just always shut it off when not riding
So does it mean that you bypass the fuel pump with the new petcock valve modified and you go directly to the carburetor?
Essential mod on these ! I did my ltz400 with the same one as well . Old school simple,but effective. Lawyers ruin everything
This is good to know, I have a 05 Suzuki Eiger and have been worried about the OEM petcock failing. I'm going to replace it now with the Yamaha 660 Raptor petcock,thanks for the heads up video.

If your float is adjusted to high or is sticking some how , needle not seating. That’s really the only things
Good luck
Also remember to get in the habit of turning off the gas when done riding
I had the exact same problem.... I bypassed the vacuum.. worked perfect
It’s glad this video is still helping.
do you have a picture of the end result? Want to see where you installed the fuel filter you put on. What kind of filter did you use?
Do you leave the valve on "prime" all the time when running it nin normal use (i.e., don't bother with the "on" position)?
Yes, prime if you’ve plugged the hose. Get a new valve and remember to turn off when not using
Thanks Real Good INFO and troubleshooting........Pet cock fix is Awesome

Would this also cause the float bowl to flood?
It’s possible if the petcock is letting gas into the bowl and the needle isn’t seating good it could flood. That’s why I like the manual ones so I can turn it off. Especially if I am hauling them because of the bouncing.
what if gas leaks thru constantly thru the prime setting? continually flooding it
Hi
You will need to rebuild the carburetor. The needle in the float bowl is not stopping the gas as it should
sweet .....had the same problem. Suzuki should recall that POS. Cost me 2 il changes and the cylinder was full when I tried to start it which could damage crank piston the ENGINE...what a POS. Thanks for the fix.

Thanks for the vid.
Will it work on any carb bike?
Why not simply turn it to prime and clog that vacuum line?
What position should I turn the new petcock to?
TY
RUN / OFF
Also if you leave it on prime and needle valve is stuck it will dump all of tank in crankcase off is on and reserve when engine isn’t turning over

Why not just put a shut-off valve going to the carb?
except the all the same problems will exist if you forget to manually turn off your new petcock.
thank you!
I think I have the same problem on my Kawasaki motorcycle. Except the hose coming out the bottom of the airbox is split open. But gas soaked in my airbox
Petcok valve I just purchased on Amazon $15.00.
After several years I’m glad and hope this video is still helping, just remember to turn the valve off when not using the machine
So im just a idiot and left it on prime and all the gas went into my airbox 😂😂😂 thanks now i know its not the carb
HEYO It's ME
