In this video I share my experience making adjustments to my power valve. I was really amazed at how much this adjustment changed the way my bike felt. Uncle Jake rode the bike after the adjustment as well and said it felt like a totally different bike.
I found that adjusting the power valve about 1.25 turns inwards was the sweet spot. Adjusting the power valve inwards increases the preload on the spring which increases the force required for the power valve to open, making the power valve open later or at higher RPM's. You will get the opposite effect with a counter clockwise or outward adjustment.
