Hi everyone. I have a 2001 Artic Cat 300. It keeps burning plugs. They came out very black, dry, carbon.

If you put a new plug in it will run great for awhile. Eventually it will quite running. You can clean the plug a few times and get more life out of it. But sooner or later it must be replaced.

I had the carb cleaned and serviced.
Then I tried thinning out the air/fuel mix but it hasn't helped.

I'm running DR7EA. Is there a better plug to run? Something hotter? Iridium?

The bike has had the odd electrical glitch from time to time, but is usually fine. Could this be an electrical issue? How would that be diagnosed?

Thanks :)

Check voltage at the battery when it’s running. Report back

Hi, things got very crazy busy here for awhile but finally have a chance to get back to the bike today. Voltage while running is between 12.20 - 12.90

Thanks

Your voltage regulator/ rectifier is not working. You should be in the 14’s when running.
