Thank you so much for this video. I have been screwing around with my carbs as I have fuel leaking out. They are not the easiest to work with when on the bike. This will really help in getting my floats adjusted to a nice starting point. I have searched for hours trying to find relevant info and finally found you. I have subscribed and look forward to watching your bobber build!

*level. I'm not sure this is gospel as I just set mine to that and the bike won't start now. At 14mm the sprung loaded button end is out, in this video the button is closed with the float at the bottom of the circle...and my bike runs there! So I don't know where the guy on 'that' website got the 14mm

Hey new subscriber here 😀 is there a part 2 showing this fuel level measurements. I really want to see it I've got the Yamaha part the glass tube with the mm on it but I've got to get the tubing to attach to the fittings. So you just mark the tube and see if it's between 13.5-14.5mm below the bowl line on each one and your good right??

@@fuelheadjay8800 OK I think I found the issue my hose/tube for the drain fitting was kinked. This morning the fuel level was right around 20mm below center mark on cover. So I'm guessing the float is not going high enough when it shuts off and I should bend tang up bc it should be 14mm below center mark. Is this correct?? Thanks!!!!!!!! Does it matter how long the tube is??

@@fuelheadjay8800 my book says bending the float upward very slightly to lower the fuel level; bend the tang down to raise the fuel level. If too high to rich to low to lean. So does the book mean to lower the fuel level you bend tang upward, would that mean it would make it go from 20mm to 14mm below center mark or would it make it worse???

Its probably irrelevant now because you changed to single carb, but you adjusted your floats wrong, the fuel level should be 14mm below the mark on the casing, you should check the fuel level first and then adjust the tab up or down accordingly, the floats act totally different to finger pressure when immersed in fuel

I see you have the needle valve hook with the open end facing the cover... Do you think it matters which way it faces? I know some have enclosed hooks in the rebuild kit and another guy told me the 1100's came with a enclosed one. I'm wondering why... And if the hook opening should face the carb body to kinda help keep from moving enough to drop the needle valve. What do you think? Should it be just the way you have it with the opening facing the cover and why? Thanks 👍

Mine were sticking. Found 2 vids on polishing the seats. I used light rubbing compound. Cotton bud plastic stem on cordless drill. Then finished with metal polish. I had the carbs out. The front stuck on me, again, but I had the motorcycle sitting for 2 weeks. I'm thinking to put a switch on the fuel pump to turn it off and let the bike run the bowl level down a bit to drop the float. Guess I could also drain the bowl!

@@fuelheadjay8800 I got one out. The cap is a banjo affair to allow fuel in from the fuel line inlet tube. The inner side of the inlet tube is recessed. The cap has an O-ring above the banjo grove and one can see how deep the cap must go.. The old seat also has an O-ring. That O-ring was rock hard and deteriorated. The new seats in All Balls kit do not fit real snug. Iffy at best but soaking them in brake fluid expanded the O-ring enuff where i will give it a go. The hole is slightly larger than 10mm so the best conclusion i could come to on a new cap is a 7/16 allen plug. The plug must be flush with the top or the rubber inlet boot and clamp cannot sit all the way down. Not much space between the seat hole and intake rim, making fashioning a puller a pain. Underneath the allen plug i will insert a 10mm stainless spring .1 wire and cut to suit depth from bottom of installed allen plug to seat to hold seat down into place.. The hard part will be drilling the 25/64ths hole in the 10mm bore to tap for plug. The plug will probably have to be ground shorter at best. Teflon tape for gas.. to seal plug. After that's done replacing seats will be easy. If the new seats do not seal; the pain is having a go at installing the carbs again. I imagine carefully J B welding the upper rim of the seat as little as possible if necessary. Also the old cap must regulate pressure so the spring may serve in that capacity if cut to length properly. Probably as long as possible without binding the plug when installing the new plug flush with top of seat bore.

Hi there! Unfortunately I had to remove both floats, because the last owner bent them wrong, so they got stuck in the valve opening. Of course both valves fell out. Cleaned them and adjusted the floats correctly. Now the bike wont start. Could it be to lean now even though its to spec or could the valves have been damaged? Thanks in advance

I did mine again like this and if I set it to the mark it shuts the fuel off and when I let fuel out it still goes past 14mm to like 20mm below if I bend the tang down it lowers the fuel level in the tube even more to like 30mm? I can't get them to 14mm or 13.5-14.5 and they are brand new floats and needle valve assemblies. Please help!! I'm using the Yamaha tool but it has a 6mm tube with plastic tube same size so I made it into a couple sections to make it small enough to fit the drain hose fittings. Could this be my problem? I'm going to buy 3mm tubing but weird all the books say use the ym part of clear viny tube and measure it from the mark on cover.

@@fuelheadjay8800 hi, ty for your answer. I wish you have a nice week. actually I test valves again. when I made your setup gasoline can not rise enough. as you can see there is 2 pins inside of the carb. little one in the bottom takes the gasoline inside the structure and it needs to rise to de upper yellow screw. which it has the throttle needle. so, i tested again with a piece of transparent pipe, gasoline only rise to the half of the carb. so I just want to look what is going to happen and take down the float arm as much as I can do. off course gasoline came to the top of the carb. and I tried again it is not working :) now there is two ways to fix this I think -; I will find a singe carb kit or I will buy a carb repair kit. i will let you know the results. thanks

@@fuelheadjay8800 Floats are fine. Had my neighbor verify my needle height setting. We did this with covers off and manually held floats closed and slowly opened each till gas flowed. Only slight adjustment from what I had. Put covers on, cranked until engine fired up. This was a weird issue. I don't believe float height adjustment needs to be this accurate. I still believe there was another 'hidden' issue. Weird tho, with covers off, floats held closed, the fuel pump stalls. With covers on, fuel pump runs and runs and runs. This was giving false assessment of the situation. When the motor was idling, the fuel pump would stall, fuel level reached in bowls, and then run again, fuel level drops. I'll need more convincing this was not down to minor float height adjustment. Time will tell.

@@fuelheadjay8800 Just had a thought. My initial problem started when I installed two new float needles that caused fuel to overflow out top of the carbs. I replaced with original needles. The new needles measured about 1mm shorter. Anyway, in case this happened again, I put the drain pipes into plastic bottles and let hang down from the carbs. Every time I would try run the engine, I'd have the bottles hanging. After adjusting the floats as previously mentioned and motor started, I did not have the overflow pipes/bottles fitted. I wonder if when the covers fitted, air was trapped in the bowls preventing the floats from raising due to overflow pipes hanging down 🤔. When pipes removed, the trapped air could escape.
