Yamaha 2002 TTr 250

Hi. The TTR is stock. Went to start the bike after the winter season and the bike will not idle. New gas, plug & oil. The bike starts under choke and will cause the exhaust pipe to run cherry hot. The plug is running lean. I have good exhaust pressure and intake is sucking air. I pulled the carb off and clean out all main jet and cartrige as well.
Help!!!

Hi hoeygatt

Look around your bike near where the throttle cable meets the engine, when you pull the throttle, the cable pulls a quarter circle piece of metal which is connected to a spring, then connected to that should be a screw, that is the idle screw, turn it very slightly, usually clockwise to make the idle higher, and this should sort out the problem.

Has the bike been stored for any long length of time?
old fuel in the carburetor will turn to a varnish like residue blocking the jets,or possibly water in the carburetor.

2000 yamaha ttr 225..no powe


Trace the starter wire to the solenoid. Any loose connections? Check the other heavy wire to the solenoid. It should have power present at all times. If no click from the solenoid when the starter button is pressed, check the wiring connections coming from the handlebar. Lastly, look at the starter switch for possible damage from the spill.
