    Are my piston and cylinder shot?

    The way i diagnose a bad piston is i will have my bike off, clutch disengaged if your bike is easier to push forward than what it was before it is it is a bad piston if you dont have any airleaks/gasket leaks

    If its not a airleak it might be a compression issue have your bike off with the clutch out if its easy to push forward your piston is going bad which causes no power.
