TTR125 Carburetor with Fuel Switch Valve Petcock, Compatible with Yamaha TTR125 2000-2007 TTR125E TTR125LE TTR125L, Complete Carb Assembly Replacement for Yamaha TTR-125 Dirt Bike

Carburetor was a perfect match. I even used my old slide and choke cable. Bike started first kick and runs better than the stock carburetor.

This is my 3rd replacement carb over the last 12 years on my 2003 TTR125. For a ranch bike it gets abused pretty good, so I consider it normal wear and tear to replace the carb every so often. This carb works great out of the box. I'm at sea level so there are no adjustments/jetting changes were needed after installation. The stock vent hose setup is not used in the same manner, so the other two fittings (other than the fuel inlet and bowl overflow) are simply vent tubes, connect and run the provided hoses down along the frame in front of the swing arm for a clean look. Ensure the air intake nipple on the head side of the carb connection boot is also capped off as well or it will backfire and do crazy stuff. After install, no choke is needed and starts first kick. Keep clean relatively new fuel in the tank, and shut off the fuel line when not in use. Do all your routine maintenance and this will last a long time.

I recently picked up a 2000 yamaha TTR-125, and after diagnosing why it was not running I found that the carb was fouled beyond rebuilding/repair (someone ran 2 stroke gas through a 4 stroke bike, probably several tanks worth). Long story short, I saw this reproduction carb and read some of the reviews. I figured for less than $30, it was worth the risk. I pulled the old carb off, slapped this bad boy on, and had the bike turn over on less than 5 kicks (after the gas actually got to the carb). I had to adjust the idle screw, but that is a standard expectation for any non EFI engine. Now on a warm day, it takes a single kick to get the bike running. I cannot speak to newer TTRs, but if you have an older one like my 2000, this carb works flawlessly, and did NOT require any modifications to install.

Read all the positive reviews and figured I'd give it a shot for half the cost of oem rebuild parts. Unfortunately mine had poor quality castings or the finishing work wasn't completed. Ran super rich - figured out the choke plunger couldn't seat all the way due to flashing on one of the ports. Got that cleared out and the plunger sitting flush, then it ran super lean at 1/4 throttle with proper jetting. Couldn't get that lean spot to go away even with swapping needle from original carb. Gave up on it and rebuilt the oem carb (needle&seat, all gaskets and diaphragm). Spent three times as much in the end, but back up and running well.

Bike fired right up! Ran and rode great but the over flow for the float bowl dumps gas out. Have pulled it apart yet to see what’s making it stick.

The stock carb on my TTR125L sucked. This item I would give the finish an 8/10 but the bike fired right up. I ended up replacing the jets and the needle with Keihin parts because I am in the mountains the what came on it was not the right jetting for me. Bike shops suck and don't have the big box of jets like they used to so I am only 95% jetted correctly until I source some smaller jets. The bike runs great even jetted slightly off, most people who ride the bike don't notice.

I’m very happy with this carburetor! I purchased it for our 2002 TTR125L, and it’s been absolutely fantastic. The bike starts up on the first kick every time, and all I had to do was install it—no tuning or adjustments needed. It’s truly plug-and-play!

Works good, only came with two lines, so you will need an extra line and a fuel line. Also the floats seem to be of lesser quality because they tend to get stuck but bike runs well.

Works, fit great

There is no choke on this carb

Very happy with the purchase. Runs like a dream, probably better than the original. You just have to modify the throttle to one cable instead of two. Otherwise bolts straight on.

Bike ran like a charm after installing this. Good buy :)

Fit great on my 04 ttr125L. Runs great aswell! had to adjust the idle a hair and we were laughing.
