SOURCE: How do I adjust the valves on my 2003 Yamaha Warrior YFM 350X?

first you need to remove everything that covers your valve covers(gas tank etc.) remove the intake valve cover,and the rotor nut and timing plug.set the engine a t.d.c.(top dead center)fit a socket onto the rotor nut and turn it counterclockwise until the"I" mark appears align it with the index mark in the timing hole.use a flat feeler gauge between the top of the valve and the adjuster.loosen the locknut and turn the adjuster just until you feel resistance on the feeler guage.hold the adjuster and tighten the lock nut down.i can not tell you the min.clearance spec to your quad since i have a 660 raptor.try using the smallest clearance number.

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

SOURCE: i have a 2003 yamaha 400 kodiak runing fine and

I had the same problem on my 2003 Kodiak. It ended up being the CDI Box. The Warn Winch was the cause. I had to replace the CDI Box on my twice before figuring out it had to do with the winch since it happened only after using it. I used the winch before when new and never had a problem.

89 Polaris Ranger500 6x6 side by sideis coughing,spitting and backfireing thew carb.whats the fix


I would start by pulling and cleaning the carb, air filter and spark plug. Usually the cause starts with dirty air filters that gets the carbs dirty which then cause the polaris to run rich and the plug will start to foul. The unburnt fuel ignites at the wrong time and back fires. A less likely problem would be out of timing.

Hi bird atv 200 no sparkcan i by pass ignition


No you can't bypass the ignition. There could be many problems for not having a spark. If there are points then make sure they are set properly or just replace them and set them to the right gap. it could also be a shorted or open capictor. It could also be the ignition coil or a bad connection especially the ground wire.

Good luck,

Marty

Ignition timing is done by the ECU and can't be adjusted; camshaft and balance shaft timing done during engine build-up

It will turn over but wont crank


Not starting issues are usually spark or fuel problems. If you have gas getting to the carb then check your spark. First check all the wire connectors and plug wire to make sure everything is connected. If you find a loose connection fix it then try it. If not, then remove the spark plug but leave it attached to the plug wire set it on the cylinder head and turn the engine over. You should see a bright spark. If you have a really weak spark or none at all, then it may be your ignition coil or a related ignition part.

Cherry red exhaust and back firing through carb


sounds like your ignition timing is too far advanced allowing the petrol / air mix to part ignite in exhaust.

Where can I find the exact timing sequence for a suzuki four wheeler


every four wheeler I've ever worked on has the ignition timing fixed and controlled by the CDI. Mechanical timing usually invovles lining up the T on the flywheel with a mark on the cam shaft. you'll need a service manual for more specifics.
