Amazing Matt. I've a xj400 just bought it off a guy...it was laying up for 6 months. So need to check it. Where did you get that owners service manual. I need one.
ATTENTION READ THIS, another problem he did not mention that is very easy to fix is the float getting stuck, all you have to do is hit the float bowl with a screwdriver/hammer a few times. Try that before buying anything always works for me
My grandson got his first brand new 50cc bike from Santa but it leaks gas already. I haven't seen the bike yet but will pass this on when I see him. He is almost ten. Thanks 👍
I have a fuel tank with a fuel tap just like that (with the nut/screw fixing to the tank) I have completely stripped the paint and there are no holes in the tank, repainted it 3 times now because the fuel leaks out of the tap connection and ruins the paint work again. I have bought a brand new OEM replacement tap, filter and o-ring seal. Im slightly hesitant to put it on incase it damages the oring.(cant seem to find the one that fits without buying a new tap?!?) My question is, what are the things to look out for when servicing that area? Thanks in advance.
#SUBSCRIBED,....I HAVE AN 97 TL1000S AND I REALIZED MY FUEL TANK IS LEAKING FROM WHERE THE FUEL PUMP IS....DO YOU HAVE ANY VIDEOS ON THAT OR KNOW HOW I CAN FIX THIS.....THANKS
I have got a Yamaha Yzf R15 sport bike and I'm getting gasoline smell every single time I start her up. There has been a significant drop in mileage and I'm guessing that the culprit is cracked fuel lines. My bike is fuel injected and being a sport bike, everything is behind the fairings. Could you possibly make a same video on sport bikes???
I have two rubber hoses under my bike. 1 has a cap the other doesnt. They are bound together. My problem is just today I noticed after riding home from work the uncapped hose is leaking fuel . How do i fix this and what would be the cause of it?
Can I take the bottom part of the carb off and replace the gasket without removing the whole thing from my bike? I have 1975 Honda CB750 and it appears that the 1st carb is seeping a little bit. Not sure exactly from where, but the side of the carb will get wet from gas and occasional a drop or two will end up on the engine below. I've had a couple mechanics tell me not to worry about it, but it seems like something I should deal with.
Can you try and explain to me why whenever I move my dirt bike petrol leaks from the outsides of the petrol cap ?? Seems that it’s such a simple but uncommon problem there are no videos about it, should I simply buy another petrol cap or is it because my tank is too full ?
My Suzuki Rmx leads out gas where the on and off levers is. The fuel Line seems fine. But it’s still leaks. I need uegnet help if you got any idea of whats wrong please contact me. I can’t get to work today without it.
I have a 1981 Honda CM400T that if I jump the cylinoid the bike will start and run but I try using the start button and my head light blinks off but does not start the bike what could it be
I have a problem with my 150cc scooter it starts up fine..... But after 10 minutes the bike refuses to start due to fuel pouring out the exhaust......wat can i do to fix that problem
So totally ignore the spring and plunger inside the needle? And totally ignore the inside of the valve seat? And totally ignore the o-ring around the valve seat? SHEESH 🙄
Well, not realy, all that will happen if there is a fuel leak it can get on various parts on the engine and catch on fire so no but make sure you clean all gad off, maybe a rinse with the hose
If your fuel valve does not have an OFF position but instead has a PRI or PRIME position, READ THIS BEFORE YOU ATTEMPT TO FOLLOW THIS VIDEO'S INSTRUCTIONS. There's something this video doesn't cover, and it can result in serious damage and injury. It's downright irresponsible to NOT cover this. When the video talks about shutting the fuel off on the valve, it shows putting the valve in the middle position, marked "off". This is fine, if there's an off position. But what if your valve has one marked "PRI" or "PRIME" where the OFF is on the valve in the video? Well... DON'T SET IT TO PRIME. Instead, LEAVE IT in the ON position. See, here's the thing. If the valve has an off position, the fuel is fed into the carburetor by gravity and gravity alone. That is, any time it's set to ON or RES, fuel will flow if there's anywhere for it to flow too. However, if it has a PRIME setting, then in the PRIME position, the fuel will flow like with the other type if it's set to ON or RES. However, with a PRIME setting, if it's set to ON or RES, the fuel will ONLY flow if there is vacuum. With a valve that has a PRIME setting, there are two hoses that attach to the valve. The fuel line and the vacuum line. When the engine is running, the pistons moving creates a vacuum. Using a vacuum line attached to one of the vacuum nipples on the carburetor(s) that goes to the vacuum nipple on the valve, the resulting vacuum is transmitted to the valve and causes the valve to release fuel. Unless there is vacuum, no fuel will flow in the ON or RES positions. Because of this, the carburetor bowl will eventually dry out if the valve is not left in the PRIME position. This has the benefit of not wasting fuel and also limits varnishing of the carburetor bowl and needles. However, it means that if the engine is not run for a sufficient length of time, the carburetor bowls will be bone dry and the engine will not start. Running the starter motor WILL cause some fuel to flow into the carburetors, but it's just as likely to wear out your battery and starter motor. This is what the PRIME setting is for. It allows fuel to flow into the carburetor without a vacuum. So what you would do is set the valve to PRIME for 5 minutes before you attempt to start the motorcycle. This gives sufficient time for the fuel to fill up the bowls and you'll be able to start it with a lot less cranking. Once it's started, it's a good idea to set the valve back to the ON or RES positions. So as you can see, if you have a vacuum actuated valve, then the ON or RES position is functionally equivalent to OFF when the engine is not running. You can however install a shut off valve in the line so that it won't get fuel even when the engine's running, but why though?
Excellent video. I chuckle every time you say 'seek professional help', makes me think I've got a screw loose. 🤪
Liked your video so much. It is clear and to the point and covered the problem completely. Thanks.
No no no.
AWESOME! You could be a college instructor, very well presented! Plus, I'm pretty sure these carb kits I ordered will fix my fuel problem for sure.
I have a Honda xr80r and I was wondering if you put the setting “fuel on” next to the choke while your riding? Plz reply
Thanks bro. I owe you the 6 hours you saved me. First video yessssss!
you are very clear and concise, your video is easy to watch. thank you!

Replace fuel pump and all fuel lines connected to it for best results

I have same problem my tank is almost empy at i have the same problem
Is the needle valve the same as the float valve?? I have fuel coming from bottom of carb
My Suzuki Rmx leads out gas where the on and off levers is. The fuel Line seems fine. But it’s still leaks. I need uegnet help if you got any idea of whats wrong please contact me. I can’t get to work today without it.
I have a mean dog 2 trike my carburetor is leaking. What should i do. I was leaking where the air filter is located
Thank you for this!
Soooooo good... 😊 thanks for uploading this helpful video..
How to recover fuel tank leakage ?? Any suggestion as because i am suffering for it
Its also good if your changing the float neddle to clean out the seat it goes in
I lifted the tank on my 06 gsxr1000 and notice gas leaking from the overflow hoses. It wont stop leaking. I didnt disconnect anything
I have a 1981 Honda CM400T that if I jump the cylinoid the bike will start and run but I try using the start button and my head light blinks off but does not start the bike what could it be
Gas is leaking from the little brass piece my fuel line is connected too, any idea as to why? Or is it caused by similar reasons in this video?
It’s prob just a bad fuel line
I have a problem with my 150cc scooter it starts up fine..... But after 10 minutes the bike refuses to start due to fuel pouring out the exhaust......wat can i do to fix that problem
Thank you so much!
When i dropped my bike, glugs of fuel gushed out somewhere from the bottom, what should I do?
At the end of the video, he says check your engine oil. How would gas get in there?
My bike smells like gas while riding when I shut it off it's fine any ideas?
So totally ignore the spring and plunger inside the needle? And totally ignore the inside of the valve seat? And totally ignore the o-ring around the valve seat? SHEESH 🙄
With Smokey how could it not be great
Yamaha r6 having that issue has poured out
Idk why but he reminded me of Johnny Knoxville
...
Can it destroy the bike?
Well, not realy, all that will happen if there is a fuel leak it can get on various parts on the engine and catch on fire so no but make sure you clean all gad off, maybe a rinse with the hose
