Title: It's alive.....
Review: In the words of Dr. Frankenstein, "it's alive"!!!! I feel as if my bike just literally came alive. It's a 2011 Hayabusa with 638 miles. It was rediculous before but felt slightly held back like it wasn't breathing correctly and had a slight backfire. After exchanging the air filter, adding Castrol Power 4 RS racing 10w40 full synthetic and a K&N; oil filter, the bike came alive. It's fine now! I can feel it in the trottle.Shipping was really fast!!
