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

That’s what I like to hear!

[@earlebaker2440]

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.

[@TomsTinkeringandAdventures]

@@earlebaker2440 good call, I only recently picked up a Torx set to remove those screws. I guess next time!

[@jeepurz57]

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

[@TomsTinkeringandAdventures]

Glad to hear it helped. Thanks for watching.

[@RichardKalina-i3g]

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.

[@TomsTinkeringandAdventures]

Thank you, I have been using JIS drivers for several years and mention it in many of my videos. Always good to keep putting the word out, it’s how we help people learn.

[@namdarbolour9890]

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.

[@TomsTinkeringandAdventures]

I hate FOD! I did enough years in the Navy that I dealt with that program, but you’re right…my workbench gets dirty sometimes. Thanks for watching!

[@tom535]

Hey great video Tom thanks for your time..

[@TomsTinkeringandAdventures]

Tom smales and from what I have heard the bike is running

[@airdreams1]

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.

[@TomsTinkeringandAdventures]

The fuel turns green and thick after it sits a long time. If you search my channel I have worked on the 125 a lot as well. Good luck.

[@millsap5206]

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!

[@TomsTinkeringandAdventures]

Good luck with it, I forgot about that plastic piece.

[@aol11]

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

[@PathmanathanMohanathas]

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

[@TomsTinkeringandAdventures]

Not every float needle seat has a filter, but yes they are important to check.

[@tobyl9823]

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.

[@TomsTinkeringandAdventures]

toby lampson I suppose you are right. Cleanliness is important!

[@Crowbargreg]

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.

[@TomsTinkeringandAdventures]

Greg Booth thanks, most of the time the float doesn’t need to be messed with.

[@user-gn3yb6sb6s]

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

[@TomsTinkeringandAdventures]

I actually did this for a riding buddy, he picked up the kit so I’m not sure which one it was. I’m sure a search engine will find it for you, thanks for watching.

[@edrickspittle8536]

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.

[@TomsTinkeringandAdventures]

I don’t know if anyone makes an aftermarket unit for that bike, so OEM may be your only option. The TTR225 is a very similar model so parts from that machine may work as well. eBay may have some used parts if you want to go that route. Good luck!

[@eyeslo4206]

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

[@TomsTinkeringandAdventures]

Thank you, I am not a professional...just a guy working out of my garage.

[@eyeslo4206]

Oh I didn't mean it like that. I was actually hoping it was a pump when I first got my xt225. Even though I was disappointed to find out I didn't have a pumper carb, the air cutoff valve does a pretty cool job too. Yeah, I'm just an oldschool MX'er. This 97 xt225 is the newest bike I've ever had.

[@TomsTinkeringandAdventures]

@@eyeslo4206 I didn’t mean to be disrespectful either, always glad to learn. The XT is a good little bike. Thanks for watching.

[@dulhara2k]

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?

[@TomsTinkeringandAdventures]

It might run with that carburetor but it probably won't run right. You can either buy a new carburetor through Yamaha for a lot of money or try to find a used one on eBay or somewhere else. Otherwise a Chinese carb from Amazon could work, but they are hit or miss on how well they work.

[@dulhara2k]

@@TomsTinkeringandAdventures ok I will try. Thank you 😊

[@refugeinc.159]

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?

[@TomsTinkeringandAdventures]

Older carburetors only had a pull cable. Someone may have installed a newer throttle housing to your bike? Just my thoughts.

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???

[@TomsTinkeringandAdventures]

Jonathon Helpman I think that is a flat slide carburetor. Supposed to be a performance part but it’s going to need to be jetted properly. I don’t have any idea where to start on it, you’re gonna need to research a bit. Good luck

[@josephvargas8817]

How much does a carburetor costs ?

No idea. There are cheap “clone” ones available online but sometimes they don’t work great.

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.

[@TomsTinkeringandAdventures]

I used Google translate, so hopefully I got it right. You want to change the carburetor diaphragm. You can order just the diaphragm for many carburetors, I am not certain if you can get it by itself for this model. You may have to order the entire slide with the diaphragm. I have not changed on on this model, but it's usually a snap ring type of a clip on the top of the slide. I hope that helps, good luck.

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

[@TomsTinkeringandAdventures]

The jets inside the float bowl get screwed all the way in. The mixture adjust screw (with the spring under it) gets lightly seated and then back it out about 2 turns. It should be adjusted when the bike is running at idle. TW200 should be the same.
