    Clutch Noise

    I always heard these ZRX engines run pretty quite (not talking about exhaust noise) and if there is much noise coming from the engine it should be looked into. My engine is quiet when the clutch is pulled in but when I let it out I hear a pretty significant mechanical sound I don't like. Is this normal, should I worry? Maybe I can get someone local to hear it.

    open up the oil filler cap and inspect the clutch basket for damage. If damaged, contact kwick for a starter chain tensioner tamer.

    I thought of both of these possible sources too but wouldn't these be unaffected by whether the clutch is pulled or not?

    Both should be checked anyway - particularly the tensioner since it can destroy the engine.

    Both are affected by engine load.

    Ah okay, sorry, I did not know that (among a million other things ). Something to be learned every day...
    I thought the tensioner would only hammer on the basket while starting.

    Re: Clutch Noise

    I should have mentioned I installed a Kwick tensioner just a couple weeks ago. I'll check to see there are no marks on the basket just in case I did something wrong. I'll look for the alternator loose bolt as well. If that is not loose I'll need to compare the noise (only when the clutch is out in neutral) with somebody else's engine.

    Maybe I can cruise by Ca Pete's for expert advise.

    Pull the slave cylinder off and pull the clutch rod out. Clean, lightly oil and put back in. Also clean the end of the slave where it makes contact with the rod.

    If that end gets really dirty or dry it could give you a little noise. Something easy to check.
