Due to this fact the amount of mass is large which includes the two pistons rings connecting rods wrist pins.

The 30-degree offset creates a 90-degree firing order that produces a smooth power delivery especially at higher rpm and the power pulses of a 90-degree firing order may improve traction in some off-road riding situations. A Harley engine has two pistons. Harleys air-cooled engines have 45 cylinders with the pistons sharing a single crank pin giving the uneven 315 405 firing order that people know but that wouldnt work on the Pan.

The 30-degree offset creates a 90-degree firing. So heres the firing order. The 30-degree offset creates a 90-degree firing order that produces a smooth power delivery especially at higher RPM.

Instead of one piston firing every 360 degrees a Harley engine goes like this. This ensures that no spark is wasted and is another noticeable improvement over the previous. So heres the firing order.
