Yamaha XT225 Carburetor Rebuild 

You missed a very important piece that you didn’t remove, the two screws that holds the emotion tube holder. It has two torx tamper resistant screws, it needs to be removed and replace two o-rings on the plastic tube. For some reason not one rebuild kit has these o-rings so you need to order 1mmx12mm ID and 14mm OD. These get brittle and can break, when so they will leak and your carb will run rich.

Just bought an XT225 03'. Running really bad on deceleration and full throttle. BE CAREFUL WITH THE PLASTIC COAST ENRICHMENT COVER! Its very prone to breaking. Decided I would do a carb rebuild just so I know what has been checked and fixed. You talking about the o-ring at the top of the coaster enrichment cover made me realize mine was broken at that right angle. Purchased a new one from Rocky mountain ATV MC and went to install it with a new o-ring and BROKE the same spot on the new one... Guess I torqued it down too tight. I ordered another and I'm hoping it fixes everything!

Great video. Got me out of trouble yet again as I found the carby a lot different to the xr when I opened it up.thanks heaps

Hey bro, I have a serow xt 225 bike, but I haven't original carburetor. I put 125 bike carburetor. Is it good for bike or how can I buy a original carburetor?

I reckon that you have missed one important part of the float needle valve filter. This very important part of the fuel filter.

Great video, thanks. You took a lot of time to show everything clearly. One lsuggestion I have for your workbench is, clean up all the drill shavings and other debri before putting all those brand new parts on the bench. Is it possible that some tiny particle may be picked up off the workbench with one of the parts you're installing, and block the tiny carb orifices? Could be a nightmare to track down! I worked in an engineering company factory, and we got a lot of training on FOD (Foreign Object Debri). Thanks again for your great contribution to we MC mechanics.

Thanks man, could not for the life of me figure out where the tiny leftover o-ring went.

Nice problem solving. Way to go looking out for your little buddy to keep him riding

Thanks for the Vid! BUT from the point when you drill out and remove the idle air-gas mix screw plug cap, I noticed you do the entire job on top of that black cloth that is glittering with drill shavings(and other particulate debris). One tiny fleck sticks to your finger/skin/ or a part long enough to carry over and drop into your assembly/ rebuild. Jus fwiw.. peace bro.

How much does a carburetor costs ?

Hey Tom liked your video. Just a little help for you. I understand all Japanese Equipment have what looks like Phillips head screws. When trying to remove them like your friend did they end up getting stripped. The problem is that they look like Phillips but are J.I.S. or Japanese Industrial Standard. Most people assume Phillips and in doing so ignore the reality and how the assemble works. Phillips is self removing in that when torque is achieved the screw driver jumps out. JIS can have a torque setting and not. So what is needed is a JIS screwdriver. They are not common but can be sought out and the nice part is that JIS can be used in removing Phillips. Just thought you could add that to your tricks.

Just bought a TTR 225 and 125. Have not ever worked on one of these carburetors before. But it's basically identical to the ttr225 that I'm working on. Wasn't quite sure how to get the emulsion tube out because it's so seized in there. At least I know I'm going the right direction tried to push it up. This entire carburetor was filled with some sort of green dye or something. Whatever it is it's thicker than 90 weight gear oil. Sure that's was in my tank as well. It won't even hardly dribble fuel out of the petcock. So yeah I'm going to have a lots of fun. Get all that done and then I get to work on the 125. I did fiddle with it a little bit and got it running but there's something rattling. I think it may be the timing chain tensioner. But it's also smoking so it could be the Piston itself I'm just not sure what the exact compression should be. I don't have a compression tester small enough for that size head. Just another tool that I'll have to go by.

Great vid, you saved my bacon, had an O ring left over LOL, I know now where it goes.

Hi Tom, im a big fan and thank you for the videos, they re very helpful, i need a favour, i need to get a complete rear disk break unit for my Yamaha Serrow 225. Can u help me with it, names and brands cz mine was lost by the machanic few years ago.

My Yamaha XT has a pwk34mm carb in it.. The bike doesn't run right. It doesn't look like that carb. What kind is it???

Please update to set correct float height its .56 to .59 front front flange which angles up. You measured from middle flange that would make your float to low. Thats why there was a 1/4 space. Measure from front float was correct to begin with.

Could you share the link for the rebuild kit you bought?! Awesome video, helped me out so much!! Keep up the great content 👍🏻

Thinking you are really good at puzzles! Great Video!

Dear Tom. Many thanks. I really appreciate the clarity you provide.

I have the same carb on a 87 TT225 I just picked up. Im confused tho, as theres two throttle cables coming out of my twist grip, yet only one place for a cable to hook up to on the carb (like the carb in this video). Any ideas?

i need you help , i have a yamaha xt 225 whit the same carburator

Thanks for all the great videos. They help so much.

Tom's Tinkering and Adventures , buenas noches quisiera que me ayudara como cambiar el diafragma del carburador de gasolina de la moto xt 225 Yamaha este se averió pero no se como se remplaza, gracias.

How do I find a new carb for a 2006 xt225 Mikuni BST34 x 1.?... vin is JYA4BEE046A080581

Good evening sir, can i ask if the xt225 carburator and the ttr225 carburator are the same. Hoping for ur answer sir... Thank you....

Hey great video Tom thanks for your time..

Brass washer. That funky washer.

1:50 mixture screw cap removal. 8:20 and 10:20 emulsion tube. 12:10 mixture screw.

It's not an accelerator pump. It's the air cutoff valve. Prevents popping on deceleration when you cut the throttle.

Idle jet screwed all the way in? Would this be the same as 2015 tw200?

Thanks!! Very Good!
