Default Hotter Spark Plug

Do they make a Hotter Spark Plug for a Warrior. I have a Stock one in it now. I have put a new piston in and had it bored. I also rejetted the main jet from a 145 to a 150. Was told i needed a hotter plug. Any Help

Yes you can get a hotter plug for your quad. Why do you think you need a hotter plug?

After the new piston. Right when i first start it when it has sat a day or 2 get a little smoke on the choke. Soon as the choke is off no more smoke, But i do have a smell of Buring Gas. I was told that because of the bigger jet in the carb it might be putting to much gas for the standard plug to burn off

You don't tune engines with a plug change. If your engine is getting too much fuel you need to jet down the main jet size.

Correct me if I'm wrong but the coil only puts out so much. We run 3 different plugs BR8ES,BR9ES, and BR10ES. Yes the 8 is hotter but all it means is there is less ceramic around electrode to disapate the heat so they call it a hotter plug. It isn't that it has more intense spark. I would agree to check the jetting to make sure it's on.

A colder plug will pull more heat out of the combustion chamber. A hot plug will pull less heat out. You are correct, the plug heat range has nothing to do with spark output.

Here is some good reading about sparkplugs if you want to learn about such things.
