Hey everyone. I am currently building a js550 650sx conversion. I have a coffman exhaust and waterbox. I believe carb is still stock but that is subject to change. Was wondering what prop I should run? Also is 130# compression decent? Or should I take it apart, hone or bore depending on how bad it is. Leak down tester is on the way. I am also tossing around the idea of a high comp head. Thanks. I should be able to post pics this weekend when I get a day off.
