    Question FZS engine noise

    I just installed a Riva B1 on my SC after completing the install I hooked up the flush valve, started the motor up and the engine was running rough, I shut the motor off and could hear a noise from the front of the ski like gears still running as it slowed down I have 140 hours on a 09 FZS. I am confident the SC was installed properly and I always heard a sound like marbles in the front side of the motor at idle, any one have any suggestions...

    Thanks,
    Nick

    It never made this much noise, sounds like gears grinding. Before putting the SC on everything moved freely, I also made sure the spur gears were coated in oil... I just don't want to damage the engine, I always heard a marble type sound from the front of the ski. Is there some kind of clutch that engages the SC under throttle?

    Thanks,
    Nick

    Every time my clutch failed it would start making a LOUD growling noise right before it would go. With 140 hours I have very little doubt you have a clutch going, Julio...

    That is correct Mr. Julio. Every clutch I've changed has always made a grinding noise before going.

    you are fine it is just spinning clutch to S/c . till it goes ride it like you stole it.

    when a clutch fails you know it. you loose all boost. drive it home then. don't worry till it happens
