5th Mod, Lightened Carnk Pulley

This mod was to replace the stock crank pulley with a lighter one. The replacement pulley is 4 pounds lighter than the stock. The replacement is 2 pounds, and the original is 6. This is a large

weight reduction because it is part of the rotating mass of the engine. That means that every time you hit the gas, energy is spent just getting the part to turn, and not on speeding up the engine.



The replacement was pretty straight forward. Definitly need a cheater bar, braker bar, 22 mm socket and torque wrench.

Took me maybe 1/2 hour.

The first pic is the stock pulley the second is the replacement.
