Yamaha xs400 carburetor rebuild and theory

This video is for single overhead cam bikes mostly with within the years 1979 to 1982 before they switched over to dual overhead cam engines I go over the entire carburetor the best I can to keep the video as short as I can with out edit.
Fantastic video. I have a 1980 xs400 special sg I pulled out of a chicken coop. Hasn’t run in more than 10 years. Remarkably we got it started and we were able to drive it around until fuel was coming out of the air filters. (And a fuel oil mixture that was dripping from I don’t know where) Going to now start the carb clean and rebuild. Really appreciate the video!
@@jnelson9642 this concern is a direct fault of the needle seat (the needle on the float) You will need to check the oring on the housing and make sure it's clean and not square or broken. If all this is done then a new needle will be required.
Thank you! I appreciate the reply and the advice. This is uncharted territory for me!
Great video with awesome explanations! While cleaning carburetors, I had lost that little ball in the choke rod assembly. Any idea how specific the size of that ball is?
Going through my tool box, I found the spring and ball. Now I realize I don't have the washer and O ring. How crucial are these?
@@theMADox89 I did find a ball bearing from a old ford ignition switch. They are cheap from your local parts store. I'm not totally sure about the spring though. I can't remember if there was a spring in it as well that would work. If you don't get a OEM one I believe you will have to disassemble the after market one to get the ball. Or if you are intuitive enough, you can get one from an old parts truck, but you would need the key to remove it from the steering column.
@@theMADox89 washer and oring for what part of the carb?
I have an 81 XS200 special that I'm working on which came stock with mikuni carbs, but all the kits for these seem to specifically say 'not for 1981 XS200 with mikuni carbs' on them. Any ideas about how to get around this if I need new jets? I think the gaskets from some of the older kits will work
You can resize jets with very small drill bits. (Best to measure the bits first before drilling) If you need to go a smaller size you can fill the jet with solder and drill the size you need. I highly recommend using a drill press and the needle jet to hold the jet as the drill bits can break easily and leave you in trouble if you get it stuck in the jet.
I have a z400 with similar carb and I have an issue it runs and idle good but itll cut out and backfire as if flooding and this will help rule out fload height...measures good but hope it's the coil lol
Lovely stuff Jason!
can you do a video on float adjustment 🤔
great video. wish you had posted this sooner.thx for sharing. how did you get the float needle housing out🤔.ive had mine out once had to clamp mole grips gently on to it and pull.is there an easier way 🤔
I use side cutters on the flare end. Just the leverage of the taper side of the cutters is enough to pull the shaft out to then use your fingers for the rest.
@kuvakustom_cycles7623 thanks .what's side cutters 🤔
@@bc-mr1si Pliers used to normally cut wire
@@kuvakustom_cycles7623 ah got u.ill take the carbs off again for god knows how many times😀👍
Good video man !
hey cutie -
For banshee?
