Is It Bad To Ride A Dirt Bike With The Choke On?

The Function of a Choke in a Dirt Bike

In the cold embrace of a chilly morning, a choke can be a dirt bike's best friend.

This component, essential for the proper function of the engine and carburetor, helps in enriching the fuel mixture, ensuring your bike starts up smoothly in cold conditions.

But what happens when the choke stays on?

Running rich

With the choke on, your bike’s engine runs rich, having an excess amount of fuel, and leading to carbon buildup and spark plug fouling.

Fouled spark plugs

The carbon buildup acts like unwanted guests on your spark plugs.

This leads to the spark plugs feeling choked, resulting in you needing to change them out for fresh ones.

Bad gas mileage

And oh, the gas mileage? You can almost see your money evaporating!

Running with choke leads to poor gas mileage, adding unnecessary strain on both your bike and your pocket.
