I have a 2005 ttr 90 and it will start and idle on the first kick after riding about 10-15 min it floods out and dies till it sits for 20 min then it will run fin for another 10-15 min i put a brand new carb on it but still having problems with it running
SOURCE: engine idles fine, stalls soon as its given gas
Hi there!
Open up the carb and clean the jets with pressurized air. I also suspect water on the carburetor reservoir, before opening the carb, drain it first then run. Also, make sure the plugs are clean. Pull on the choke when twisting the accelerator, if it accelerates well, then warm the beast at normal temperature first before twisting the throttle hard again.
hope this helps-

is it just out of winter storeage? could be gum in the carbs, get some fuel system cleaner additive and put it in the gas. run it on idle and get it hot, leave to stand overnight and try again. you are not getting enough gas and when you open it up you are giving more air but not getting enough gas. try changing fuel filter too.

i used to own a yz426f and it had the exact problem... a fresh plug will fix your problem. change the plug and the bike will run great. also don't start the bike and shut it off , my bike would be fine if i started it and rode for a while getting to the proper heat range help save the plug. if my bike didn't start in one or two kicks it was usually the plug.
hope this helps

Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Drain a cup of gas from the tank. Is there 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. Spray into all the little airways and fittings in the carb. Remove the idle screw and the air screw on the outside throat of the carb and spray into the screw holes as well.

Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two 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. This process should get you back on the road.
If the above does not solve the problem then pull the slide out of the throat of the carb and move the clip on the jet needle one notch lower.
