If you have ever dealt with with the aggravating task of trying to solve a carburetor overflow issue. You know know just how frustrating is can be when nothing is working.
There are only four major reasons for a leaking carburetor.
1. Damaged or worn float valve
2. Improper float height adjustment
3. Cracked overflow drain tube
4. The ultimate killer. I worn or deteriorated float valve seat.
In this video, we are going to solve the problem before it even begins by transplanting a good float valve seat from a similar carburetor, into the carburetor I am using on my 1979 XL185.
Hope this helps someone out there!
ENJOY!

WOW,OUTSTANDING Video Cody!!! I honestly never once thought about checking a carb's "valve-seat" before,when it came to carburetor maintenance and repair! But NOW,after watching this,it will be at the forefront of my mind regarding carburetor maintenance,as my ONE YEAR ONLY 83' CB550SC has a leaking float-bowl on it,and up until now,I've cleaned every millimeter of it,both inside and outside and no matter what,it STILL leaks and I could NOT figure out WHAT was making it leak!?!? Up until watching this video,it never once occurred to me to check the valve-float seat!!! That is precisely where I'll be looking next! Thanks so much for sharing this very helpful tip to all who watched! Thumbs up!!! : >)

Nice job. I can design and have them seats made.

Let’s do it man. Email me lol or show me how

@dcyamahatech 5 месяцев назад

One thing my mentor taught me was taking a drill bit appropriately sized to the seat and then twisting it in the opposite direction so it doesn't cut the seat. By twisting in reverse by hand it polishes the seat back up and ive save numerous carbs from leaking this way.

Great vid, I'm pretty new to the world of carbs, I didn't even know the seats were press fitted on some units.

Hey Cody, I like that you explain things. It’s nice to understand why something is doing what it’s doing. Great video. On another note I do t know if you did a video on changing Fork seals on an 09 Suzuki RMZ 250 yet? I see other videos but they don’t seem to show the dust seal and the main seal in what direction. A little up close videos are pretty helpful. Thanks and great content.

Nice transplant Dr.! One thing we do, which you may have covered in the past, is to clean up the seat with a Q-tip with a little valve lapping compound on it. Toothpaste is a mils abrasive also. That would not have fixed this. Put the Q-tip in a drill to make it easier.

@TheMotorcycleMD 5 месяцев назад

That also works great! You can use automotive polishing compound or swirl remover with a q-tip. All of these suggestions work great!

The #1 carb on my CB750 had an overflow issue on the bike rebuild. Turns out as I was taking the best of it and a spare parts bike I used the float bowl from either the number 3 or 4 carb for the #1 carb. They are subtly different from the #1 in that: (1) the drain points the other way which is neither here nor there but (2) the over flow pipe is located differently and in my case rubbed against the float preventing it from shutting the fuel off.

@daveco1270 5 месяцев назад

Good job Dr. Cody, the surgery was a success. I'm surprised you can't order a new valve seat for that carb. I guess it's different for different carbs. The CB750 seats unscrew and are easily replaceable and can be found on line....as you probably know. I'm sure a decent machinist could make those seats but I wonder how much of a market there is for the specific carb? Seems like for certain vintage bikes you can find a lot of aftermarket parts, but not so much for others.

@yveslegrand9826 5 месяцев назад

I love your videos : whatever the subject, it's always entertaining and interesting. Thank you so much! About this subject, I guess anyone with a lathe can make this part from brass, or repair old ones. Besides, my heart is bleeding when I see a carb in a vice with hard jaws...😢

Makes me cringe a little too lol . Just like taking a cutter to it 😂

Awesome job. Questions about my carbs. 1984 650 nighthawk. Is there any way to test the float valve seats on these things? Thanks glenn

Re someone that will make those for you... R M Engineering (Maldon) LTD. They are in the UK , I am sure there must be something similar near you... I needed some spacers to fit my Brembo brakes to my SRAD, sent him a photo of a sketch I'd done with measurements... They were perfect.

@TheMotorcycleMD 5 месяцев назад

Thanks for the info! I’ll have to check them out!

@lochlainlewis3288 21 день назад

Nice job pulling that seat! But I'm going to take a look at my seat first. Maybe it just needs to be cleaned? I'm really hoping. Carburetor doesn't have a lot of hours on it. It did sit for a while. Maybe I didn't do such a good job cleaning it. Fingers closed.

@michaelwatson6166 5 месяцев назад

Have you done anything with the carbs on a Yamaha Thunderace? I think they are Mikuni BDSR38 from what I can find online.

@TheMotorcycleMD 5 месяцев назад

I haven’t!

@luis0luis058 5 месяцев назад

Good morning, I have a question. I would like you to answer me. I have a vt1100 from 2004. It sat idle for many years. I bought it new. After 12 years of standing still, I removed the carburetor. I cleaned it and didn't realize one of the floats was stuck. gasoline in the oil, that motorcycle has 2 spark plugs per piston and one of the rear piston spark plugs had a small drop of oil on the tip of the spark plug where the spark is produced. It is a problem with the 1st valve seal or it could be a result of what happens with the carburetor float problem, greetings!!!!

@TheMotorcycleMD 5 месяцев назад

A drop of oil is likely a non issue. If it’s not smoking like a freight train then I would not consider a motor issue. Just fix that float issue. Change the oil and ride it.

Good job. I can never see why Honda uses press in brass jets. If you don't do what you did it makes the whole carb junk. Seen the same thing with press in pilots on Hondas as well.

@tedking9793 5 месяцев назад

I would guess the reason is the cost of manufacturing. Unfortunately, most customers are so focused on the lowest price, they lose sight of the quality of the product.
