How To Service The Carburetor on Your 1994 - 2001 Yamaha YZ125. This carburetor is a Mikuni TMX38 found on the 2001 Yamaha YZ125. The 1995 - 2000 YZ125 came with a TMX36. They are very similar, so this service will cover both models.
The 1994 Yamaha YZ125 came with a Mikuni TMX35, which is significantly different from the TMX36, so this service will not apply to that model directly, but it will be close enough.
The TMX line of carburetors has two weak points; the jet block gasket, and the float valve O-ring. So before you even take your carb off your bike, I recommend you order the JD Jetting JDMK05 - Mikuni TMX Jet Block Gasket Kit. → jdjetting.com/product/jdmk05-...
It comes with the gasket, 2 O-rings, and the Torx bit needed to remove the jet block.

Thanks a lot for your videos! I'm getting my first two-stroke and interested in how the carb works, how it breaks, and what it will look like when I disassemble it, and your videos are precious to me. You have a talent for explaining things.

Glad to help!
I wish you were more thorough as the parts are very small and you went really quick. HOWEVER beggars cant be choosers and this is the best guide I found. Thank ya!
Super helpful video. I have a 2001 YZ that's been sitting for years. The carb was a mess.
Great content. You got a new subscriber today.
dude! really appreciate a well done and straight to the point video. Would you be able to explain to me what the jet block gasket does specifically? I have some weird leaking on my carb after a rebuild but didnt replace that gasket (didnt know there was one until i watched this video) and am trying to figure out what the heck i need to do next. will double check my float level in hopes that it puts me in the ballpark of not leaking. thanks in advance for any help and also for the great vid.
My throttle valve slide has excessive wear on my 99 yz125 I can't find one will other year models work with mikuki tmx36ss someone install a 4.0 it calls for a 6.5
Thank you. I have the same carburetor and it’s leaking out of the bottom drain valve nipple. Do you know what the cause of this is
Hello, thank you for this educational video, I have a same carb use on a 02 Honda cr125, look like I'm missing the main jet holder of it, do you have any supply source that I can buy it? Thanks

My spring on the carb seems to be stuck and I can’t get it out for the life of me, any tips?
can you use a TMX38 carb for a 2000 yz125 even though its suppose to be a TMX36?
I have a 1996 YZ 125 with a TMX 36. Will a TMX 38 work cause im having trouble finding 36 parts needle n seat
Are the jet block gaskets the same on the 38 & 36? Please
My tab on my float broke do you know where i could find a float for a TMX36 i cant find any online?
Use dawn dish soap. Works better than most.

Check your jet block gasket, those are a weak point in these carbs.
Question what would happen if the gasket for the jet block gose bad will it make the bike flood out ??

@@jollyshrimpo its frustrating because it's easy to find parts or new carbs for 34 or 38 but almost inpossible for 36. I will sell my 2000 yz either way because I don't really have time to enjoy it as I should. Hope you'll find a solution to your problem soon enough though.
The screws on these dirtbike are so cheap nowadays. I’ve stripped two screws before I could even dig in to the damn cleaning process 🙄🙄🙄
