Hi, Anonymous every carburetor has an idle adjustment yours is on the left-hand side check the parts fiche it's #8 in the carb section for this scenario you will need your service/owners manual if you can't find the first and best tool you ever bought for your Yamaha, despair not, for a mere zero $ you can download another one.

SOURCE: Yamaha TTR 250, Idling Problem

check the inlet manifold rubber has not seperated from the aluminium part of the manifold ,this is very common on the ttr 250 and will cause the exact problem you have,if it is seperated either replace it or repair it with some good quality rtv sealant avoid sillicone sealant as it is not petrol resistant and will turn to jelly.adam

SOURCE: Cleaning Carb Jets

not to a trained ear also go by rpm and spark plug color

NOTE: use copper wire to clean jets, sync is just thottles are same position as all carb's just leave them adjustments alone will be fine if are out use a 1/8 drill an place in between piston/butterfly to carb bore to sync/calibrate

better use a manometer for adjusting screws

depends on condition of org parts

worn = richer running

new = lean an clean

also if changed the exhaust system need to
re-calibrate carbs for max performance

Time for carb cleaning, blow the jets with compressed air and check the fuel level in the float chamber, adjust if necessary.
Tht factory plug is where the air-mixture screw is and tht plug has been kept there for non tampering!
That screw is factory set.
Basically its the primary jet which is a problem in your bike's carb, but all in all might as well blow both of them.
Hope this helps!

SOURCE: how do I adjust my carb on 2005 ttr 125

First of all, assuming that the float level is correctly set, while running the engine at idle, turn the idle adjust screw in until it starts to get rough(pay close attention). Then back the screw out 1/8- 1/4 turn. If the screw has been removed, always start by tightening the screw all the way in and then back it out 2 1/2 turns.

My husband touched the carb settings on my sons new 2007 ttr 50. I read the manual to try and find the number of turns to return to stock settings. Can you please please help!


The carb mixture screw may add air or fuel, depending on the model. If the bike will idle it can be adjusted without knowing the factory setting. What you want is the highest idle that can be achieved using just the mixture screw, not the idle setting screw. Start the motor, then slowly turn the mixture screw in. If the idle speed increases, continue in that direction. If it slows and becomes rough, turn the screw back out until you reach the highest idle speed. That will the correct setting for the bike at your altitude.

2001 yamaha ttr 125 when started it runs at full throttle without me touching the throttle


I would check the throttle adjustment screw on the throttle assembly on handle bars. Be sure it is not screwed all the way in for max throttle. You can also check the carb and be sure that the idle screw is not adjusted for high idle as well. There may be an adjustment screw on carb for the cable stop.

Hi, Anonymous and the usual suspects are:
1. Idle speed improperly adjusted.
2. Air fuel mixture screws not properly adjusted.
3. Inlet system air leak.
4. Leaking accelerator pump.
5. Loose low-speed jet.
6. Plugged low-speed jet.
7. Contaminated or plugged low-speed circuit.
8. Enrichner valve/choke not seated or leaking.
9. Multi carburetors out of sync and need to be balanced.

How do I adjust the carburetor mixture screws on a 2001 yamaha ttr 125L


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.

2007 ttr 125 wont start unless hand is over the back of carb. also wont idle.At mid and high range it runs fine. There are no air leaks and no adjustment screw for the air/idle just a factory plug.


Time for carb cleaning, blow the jets with compressed air and check the fuel level in the float chamber, adjust if necessary.
Tht factory plug is where the air-mixture screw is and tht plug has been kept there for non tampering!
That screw is factory set.
Basically its the primary jet which is a problem in your bike's carb, but all in all might as well blow both of them.

Yamaha TTR 125 L won't idle


this is very tipical. when bikes are stored the fuel varishes up the jets & needles. soak the carb. moving it back and forth in the soak solution. then blow every jet and orfice with a controlled air source. note: any speck of rust or dirt can plug these jets. pay attention to detail and do every thing twice. then install the carb and adjust it to your riding style. later Spike
