Great motor for smaller tracks or club races. I'm running one with a JP-3 pipe, and my V-Spec on Bigger full layout tracks. But, like MonkeyWrench said, take the carb off and Air-Seal it, or with some Higher temp gasket sealer right of the bat. It may not have a carb air leak, but to save yourself a lot of headache (If it does) just spend 5 minutes and seal it. Trust me... There are 3-4 VG at our track and all have had small air leak(s) around the carb at one point or another. Once mine got sealed up tight, the motor came alive! A ton of Low-Med punch with a good top end. (Empty tanks temps 220-230)
Racer Choice Air-seal is great product to have anyways. But its hard to find at time.
