1. Tour timing could be off.
2. Low compression. Check gaskets.
3. Wrong spark plug type.
4. Bad coils.
5. Fuel-air mixture is not right.
6. Other prolems, e.g. bad leads, choke/enrichment problems, etc.

Does it have spark, fuel, compression?
Perhaps the spark plug system is not sending electricity to the spark plugs.
Check the spark plug. It could be flooded. Clean the carb
appears no fire going to spark plugs
The spark control is also a REV limiter, you could replace it and chance blowing up if you like. It still wont go over 50
Purchase a spark plug spark checker at your local auto parts store, unplug each plug and check for fire to the plug while turning over.
I am not sure what to do if your Grizzly 600 Yamaha will not start. You can try taking it to a shop and having it worked on.
First check for fire at any of the sparkplugs and if you have spark then check your fuel pressure and if its not within specs then replace the pump.
possibly the ceramic resistor located on the driver side of the firewall
i have a new coil my raptor has a new starter and it trys to turn i have drained old gas and put new still wont start
probably dont have any compression. take spark plug out and put your thumb over the plug hole as you try to kick start it. if no air shoots out then its a compression problem
Could be anything, remember this: you need fuel, air, and spark to run a motor, first make sure you have that and then go from there.
