How do you remove a stator coil cover on a 2009 Yamaha Grizzly 700 atv?

It is located on the left side of the motor behind the flywheel.

Unless there is a factory notice/recall, the chance is equal one will fail before the other... Sounds like its time to have it professionally checked, being a "parts replacer" type of mechanic can be VERY expensive. You might get lucky and the problem is cured by the first part you replace or it could be NONE of the above..(broken wire, bad connection..etc..).. and then you spend untold $$$$ and not fix it!!

Replace the coil.

Low coolant level, thermostat, pinch or punctured hose, fan not coming on, (low oil level).

Glad I'm not replacing it.

possible that the fuel tank is not venting properly

The primary circuit has a ground connection so everything works... your secondary circuit doesn't have a solid ground. Go over all your ground connections carefully.

These are often called plastic side covers or cowlings. Your Yamaha dealer should be able to give a quote on the price and then you can seek the part for much less elsewhere.

tight ha-ha 45ft/lbs cheers

Sounds like bad fuel if both want run
