ALWAYS have a fire extinguisher on hand when working on carburetors. Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains then remove the carburetor from the engine.

Remove the float bowl and soak the entire carb in denatured alcohol for 30 minutes. Now clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Remove the "blue" items on the
carb and spray into the screw holes as well. Don't mess with #16 but if you must, be sure to count the number of turns and replace the same number of turns.

< < READ CLOSELY > >
Be sure to put all screws back in the same hole they came out of. IMPORTANT > do not tighten #8 and #12 adjusters down. Only screw these in until they LIGHTLY seat. Now turn each adjuster one and one half turns outward. Put the rest of the
carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine.

Remove the water trap bowl at the bottom of the petcock, (gas valve). Any water or trash in the bowl? Drain a cup of gas from the tank. Any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).

Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Install a new stock NGK spark plug and try to start the engine. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes.

Idle on ttr 90


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.

Yamaha ttr 90 jet pilot should it be open end to


The pilot should be open. This is to say that if you look through it at a light you should be able to see through it.
I suggest blowing it out with compressed air as well as the hole it fits in. While your at it give all the jets a blow out.
once you've put it back together I also suggest you fit an in-line fuel filter.
This will help to keep the dirt out and save you having ths same problem again
Hope this helps

Possible running too rich! 2001 TTR 225


First I would pull the spark plug to see what it looked like, you want it to be a chocolate color. If it is black and wet then yes you are running rich. Also check your air filter, go ahead and clean the filter. If all this doesnt solve the problem then we probably need to look at our carb.
