Hi guys. So I have this 02 400ex with a stage 2 hot cam in it, and the last time it was rebuilt, they didn’t put new gaskets in it. So when ever it’s running it bubbles out of the motor in a few different spots. There will be pics. This is my question. We got a complete top end gasket kit for it. When we have it apart should we just have it rebuilt again or no. Not sure when it was rebuilt last. Anything helps. Thanks!
