I just bought my exhaust, intake and fuel controller from them. The exhaust were at my door the next day, PCV and intake the day after. Unfortunately my dealer won't touch the PCV, so I get to see how they are with returns, lol
I order everything motorcycle related form either them or Dennis Kirk. What I really like about Revzilla is all the product review on their website. Not just their individual products reviews, but their videos on general topics such has helmets, tires, and the such.
