SOURCE: glowing exhaust header yamaha wr250f

It won't be valve timing or clearance. The fuel/air mix would be the culprit. Clean the carburetor with special attention to the idle circuit. Remount the carb with new manifold gaskets. A manifold air leak will mess up the mixture. Also, get a new spark plug one heat range colder than stock. Hope this helps out!

Please rate this solution. Thanks!

SOURCE: cant get a spark from yamaha kodiak 400

I did one about a year ago & it was the pulser coil(black plastic pickup next to magneto behind L/H engine cover) but

  1. I'm not suggesting that this is definatly the fault
  2. But id check it first
  3. I havent got the spec for it but got it from my Yamaha dealer easy enough(you'll need the wire colours as well)
  4. contact me back if you can't get them and i'll see what I can do(it'll be another week before I can get it as my phone is shot! blew the line clean out of the wall in a storm a couple of weeks ago)
Hope this helps

Yanaha maxim wont start

    • 1 Remove the seat from your Kodiak, using the latch on the rear of the seat. Pull the gas tank side covers off your Kodiak's frame. Unscrew the gas cap. Unscrew the bolts at the base of the gas tank, using a 10 mm socket and a socket wrench, then lift the gas tank's cover off your Kodiak. Unscrew the gas tank's mounting bolts with a 10 mm socket. Lift the tank off your Kodiak's frame and unplug the gas line.
    • 2 Unbolt the front rack and bumper from your Kodiak, using a 12 mm socket and a socket wrench. Pull the plastic rivets out of the front fender's center panel, then pull the panel away to access the headlights' wiring. Unplug the headlights from their connectors. Unbolt the front fender from your Kodiak's frame, using a 5 mm Allen wrench and a 12 mm socket.
    • 3 Unplug the spark plug cable from the left side of the motor. Unscrew the spark plug with a spark plug socket and a socket wrench. Remove the intake tappet cover from the top of your Kodiak's motor and the exhaust tappet cover from the bottom of the motor, using a 6 mm Allen wrench.
    • 4 Remove the pull-start cover from the left side of the motor, using a 10 mm socket and a socket wrench to access the timing port and the motor's crankshaft. Unscrew the plug from the timing port, positioned to the right of the crankshaft, using a flat screwdriver.
    • 5 Place a 17 mm socket and a socket wrench over the end of the crankshaft. Turn the crankshaft counterclockwise until a "T" mark is centered over the notch on the bottom of the timing port.
    • 6 Slide a .0039-inch feeler gauge between the intake valve and its rocker arm on the top of the motor. The gauge should slide between the valve and rocker arm with a small amount of resistance. If there is no resistance, the clearance between the valve and the rocker arm is too great. If the gauge cannot be inserted between the valve and the rocker arm, rotate the crankshaft one complete turn and take another measurement. If the gauge cannot be inserted after rotating the crankshaft, the valve clearance must be increased.
    • 7 Loosen the lock nut from the adjuster bolt on the top of the rocker arm, using a 10 mm box wrench. Turn the adjuster bolt clockwise with a flat screwdriver to reduce the valve's clearance or turn it counterclockwise to increase the valve's clearance. Check the valve clearance again with a .0039-inch feeler gauge. Hold the adjuster bolt steady with your flat screwdriver and tighten the lock nut against the rocker arm with your 10 mm box wrench.,
    • 8 Inspect the exhaust valve's clearance, using a .0079-inch feeler gauge. Follow the same method used to inspect and adjust the intake valve's clearance.
    • 9 Reassemble your Kodiak, following the reverse order of removal.

I have a 2000 yamaha kodiak 400 is T tdc or is F and does the sprocket at valve should have play in it

T is for top dead center. F is for ignition firing. I have no idea what valve you speak of but sprockets should be tight.

I've got a yamaha kodiak 400 and ca't get it to idle. Appears to be to rich. If I turn the fuel off it will idle ok. I,ve checked the float level hight and starter plunger but have run out of ideas.

change the needle valve and seat in the carb also check for debrise' in the fuel line, contaminents no matter how small can hold the needle valve open also check the clearance on the intake valve to insure proper adjustment
