Question about 2002 Yamaha TT-R 125 L

1 Answer

I have a Yamaha TTR 125 L appprox. 2000. Previous owner not sure on year. My Dad has clean the carb twice and clean everything he can with the air hose. Drained gas and put new in. Pretty much everything you should do but now it won't idle. I'm trying to help him. He's pulling what hair he has out!! Thank you for anything you can recommend.

I would remove the carb and then the float bowl, jets and fittings and soak the carb and parts in de-natured alcohol for an hour. The alcohol will dissolve varnish buildup from dried fuel. Have a thin wire on hand to aid in clearing fuel circuits in the carb body. The wire on a service tag such a used on Stihl chainsaws works well. Now use a spray carb cleaner to spray into every fitting and hole in the carb body. Spray into both ends of each circuit. Wear gloves and goggles. Done properly, this and a new spark plug should do the trick.

Yamaha 125 ttr idles to slow


Hi, Anonymous the carburetor throttle shaft wheel has two cables the cable closest to the right side of the bike is the throttle cable and the one closest to the left side is the idle cable. Right about the middle between the two is the idle adjustment bolt it faces out towards the air filter end of the carb. The engine should be at operating temperature with the enrichener off to set the idle between 950-1050 rpm. Turn the idle adjustment bolt clockwise to increases idle speed and counterclockwise to decrease idle speed. If you have access to your air fuel mixture bolt you may adjust it as well if not there is a video below on how to gain access, make sure you start with clean or new spark plugs. Gently turn the air fuel mixture bolt clockwise until it starts to bottom out "STOP" do not over tighten as it will damage the taper on the end, now back it out 2 full turns to establish a starting point start the engine and check the idle rpm's and adjust the idle adjustment bolt accordingly for 950-1050 rpm if necessary, adjust the air fuel mixture bolt 1/4 turn at a time and let the engine settle for about 10 seconds, clockwise for a leaner mixture and counterclockwise for a richer mixture you are seeking the highest rpm your air fuel mixture bolt can acquire without going past 3 full turns from bottom then readjusting the idle adjustment bolt back down to 950-1050 rpm If you can not detect any rpm change and can not stall the engine by turning the air-fuel mixture bolt all the way in then your pilot/low-speed jet is too big. Final adjustment should be made with a clean air filter mounted to the carburetor.

Hi, it appears that the floats are sticking on my 2002 TTR 125L. I have taken the carb off and cleaned it really good numerous times, and I just purchased a new carb rebuilt kit, and replaced it, to no...


Hi, Anonymous and the usual suspects are:
1. Damaged or restricted fuel tank venting system.
2. Loose float bowl screws.
3. Damaged float bowl o-ring.
4. improper fuel level in the float bowl.
5. Worn or dirty inlet valve or seat.
6. Damaged or leaking float assembly.
7. Particle contamination in inlet fitting cavity.
