    check your pipe mounts/bolts.

    Does this problem happen after you run a long time at a set RPM? If yes, then there is something else that could be the culprit; the impeller.

    Not many people know this, but these two strokes, especially the 717, have sharp resonant vibrations at certain RPM's. If you tend to run at a certain RPM, say WOT, and the resonant point of the vibration is at this particular RPM, you will never keep the exhaust bolts from breaking even if the pipe bolts, bushings and grommets are perfect. The solution is to change the impeller to get the RPM away from that resonant point.

    Or send it to Impros for the Worx (which includes balance, welding, and pitch verification).
