A 2000 yamaha grizzly 600 has no spark? I put a new spark plug no spark. I put a new ignition coil no spark. what do i do next?

The most common reason on ATVs with no spark is the pickup coil in the stator. There are test for the ignition system and if you will give me your email I will send you the procedure as decribed in the manual. I cant copy teh images to this format but can through email..

Hi i have a 1997 yamaha 350 warrior i have no spark to the spark plug what could be

hello, you probably need to have your stator checked out, sometimes the pickup coil in the stator will go out, also you can try ign coil, the one spark plug wire is hooked to,warriors are bad about cdi going out, mine would idle, would not rev up, would bog down, source coil in stator probably needs to be checked also..

Yamaha xt 125r wont start up

hello, check and see if plug is firing a blue color, if not you may need a stator-pickup coil, i have a 2000 warrior, it is firing, orange and white color, stator neede to be replaced, pickup coil was going out, also check ign coil, these have a problem with getting weak after a while. most likely it is your stator pickup coil, no blue fire from plug, no running the motor. my stator pickup coil was going out. no blue fire from plug, i was told by a yamaha mechanic, no blue fire from plug it will not run, has to be blue, not orange or white looking fire.make sure carb is clean and all jets inside are clean, and air passage ways

Hey Doug,
I would first suspect a clogged fuel filter, then ignition components and air pathway obstructions from filter to exhaust.
Sounds like the bike wants to run and does run...when it gets what it needs.
If it has a carb, check the float bowl for crud that can clog the jets. You may need to replace fuel line, but not likely.

Yamaha warrior won't start

If you are getting a nice bright blue spark then no, the last time I had a problem like this it was sugar in my tank. If you taste a bit off your finger and it is the slightest bit sweet, then some one has sugared your tank. If so just flush the tank with a little fresh fuel and then flush the carb, and fuel lines by spinning the engine over for a bit then try to start again.
Is yours an electronic ignition or points. If points gap could be wrong or even timing slipped. That has happened to me also.
