I just purchased a snowmobile to start a project, but i was curious about this motor.
The motor is a Kawasaki model is T7C440FR2A.
Well the motor is a twin cylinder, but it has 4 spark plugs. Anyone have any input on this.
I have never seen anything like that.
Thanks for any input

I can post pictures if needed later tonight.

it has dual ignition. with 2 plugs firing in each cylinder you get a faster, more even, more complete burn.

the new AC 800 and 1000 twin have that setup so it can burn the larger amount of fuel in the cylinders faster.
