well the ski is intermittent. sometimes it runs awesome for the day sometimes the MAint light comes on and goes into limp mode, new plugs, new gas no change, have checked all connectors, made sure all sensors are in correctly but have found nothing.... tired of working on skis ...

any who, the only other thing i can think of is that the ski is very shaky when engine is running, like vibrates the ski, doesnt seem right. what can it be? wear ring, motor not aligned correctly?
