Its 10:1 compression ratio is designed to add power, giving riders a noticeable increase in power and responsiveness over stock.\u003c\/p\u003e\n\u003cp style=\"line-height:1.65;\"\u003eForged construction gives the pistons exceptional strength, and the forged crown includes generous valve pockets to accommodate various valve sizes. Force-fed pin oiling provides enhanced lubrication for the piston pin, while the ArmorGlide skirt coating reduces friction and improves scuff resistance for longer engine life.\u003c\/p\u003e\n\u003cp style=\"line-height:1.65;\"\u003eThis kit suits a performance-minded rebuild or a reliable refresh. The manufacturer recommends a full custom tune for optimal performance, though the compression ratio often works well with existing fuel management systems with minor adjustments.
