The Kartboy Crank Pulley is a great way to increase performance without any sacrifice. Decreasing rotational mass reduces the strain on the engine. The lightweight crank pulley has the same effect as a lightweight flywheel, just not as dramatic.
Kartboy Crankshaft Pulley weighs in at 2.4 Pounds. A good bit lighter than stock but not light enough to throw a CE light. Free up a little crank HP and get some KB Bling.
