Where is it leaking from exactly? If it is leaking from the carb itself (not petcock) then you have a faulty needle valve. It either needs to be replaced or cleaned. Since you said it happens only when running, that indicates you have either a fuel pump or petcock that is electronically or vacuum operated. So what's happening is gas is allowed to flow into the float bowl, but since the needle valve (sometimes called a float needle) is unable to shut off the fuel flow into the carb. This results in fuel usually coming from the throat of the carb, but can also come out of any open air ports that are tied to the float bowl. Like the float bowl ambient pressure port. Long story short, pull the bowl off and clean everything with carb cleaner. If that doesn't work, replace the needle. Let me know if you have anymore questions!
I have the exact carburetor my question is with the pilot screw, screwed all the way in. How many screws out do you turn it? I’m having a problem finding that.
I'm looking at a 1982 Yamaha Seca xj550. Really cheap deal, but I'm a little intimated, as it's my first bike and I've only ever worked on small engines mostly lawn mowers😅
Don't let it freak you out my man. Internal combustion engines all work on the same principles. Just take your time and label parts if you have to. And of course, hit me up if you get stuck. I'll be glad to help!
See. I could fix my own old azz motorcycle myself. But literally videos for my bike are not on the internet. So I don't know how to take things out of my bike much less how to put it all back together. And replacement parts are impossible to find for my bike. I need a new fuel tank due to the large dent in the side of the fuel tank from before I got the bike. Rewiring needs to be redone. Carburetor will need to be rebuilt. I will need to drain the old several year old gas out of the tank. And probably need to replace the petcock. Need new blinkers since they've been broken off. New mirrors since they're broke. New battery. New brakes I think. New brake fluid. I'd rather take it to a shop and have it fixed up and basically 'renovated'. But my mother says no. Lol it's my bike. Yes I know it's going to be well over 2000$ for all that. But I guarantee they'll be able to find the replacement parts because that's what they do. They paid 400$ for it on my 18th birthday. I didn't ask for them to get me a motorcycle period. Especially not one that I don't have the knowledge or tools to work on. They know nothing about motorcycles either and have 3 others they need to get fixed. And they're wanting to pay someone to come fix them. They've all been sitting for 5+ years now without ever being looked at. It irritates me, too. They got all these motorcycles to 'ride'. Instead, they let them sit. Instead of ever fixing them. But when I want to invest in at least mine, they go, "No! That's a waste of money!" Guess what, probably cheaper than going and buying a brand new motorcycle.
It depends on what I'm cleaning. If it's not too bad I'll use simple green. If it's something like valves, heads, pistons, or anything else with heavy carbon deposits I use purple power diluted with water.
Wow man, didn't know you had another channel.. nice.
Hello friend. After you cleaned the carb did you lube up that butterfly and cinder with marvel oil? Thank you from Vegas ❤️🩹
Yes I did!
Hay man, I got a problem. I crank the bike and it starts leaking gas. How do I fix or what can it be.

Is this the ultrasonic 3 Litre model.

Was wondering the same thing

What solvent are you using in your ultrasonic? Simple Green?

What's the best place to find parts?

Bikebandit and oldbikebarn are some sites I've used in the past for quality OEM parts for older bikes.
👍
Crispy
Tried to make it as crispy as possible 👌 when are you gonna get in a video with me? Lol
