Okay guys, had holden do a lot of work for me but here is my cylinder, He's doing a lot of other motor work so I'm not going to have a review on this in the next week or something. I will post a review on it later in the year when I break my quad in and get to text the full potential. I think he charges $100 or something like that, here is the pics of my clylinder, tell me what you think!
