    Question 1987 CBR600 engine noise

    Ok – I have recently bought myself a 1987 CBR600. All was going sweet until I booked the bike in for a new rear tyre.
    The person/mechanic pointed out to me a “noise” – Oh- that’s the CAM chain they said. They then proceeded to listen to the rattle and rev the bike.
    Facts:
    1 – The rattle is only there when the engine is hot.
    2 – The rattle disappears around the 3 ½ k to 4 k rev mark.
    3 – The rattle reappears when de-accelerating again around the 3 ½ k to 4 k rev mark.

    Could this be something serious or just a mechanical rattle due to the age of the bike?

    Any advice or help would be greatly appreciated.

    Cheers

    It's a Honda.

    Honda's rattle unless:
    1. They're brand new (and even then that's not always true).
    2. They have gear-driven cams (and even then that's not always true).
    3. They're two-smokes (and even then that's not always true).
    But don't panic!!

    Aftermarket camchain tensioners are available, so you can dispense with those horrible Honda ones. And they're easy to fit, and all that.
    http://www.cbrzone.com/sprockets.html item HT600 is the one you want.
    ... and that's what I think.

    Or summat.


    Or maybe not...

    Dunno really....

    yep, sounds like a cam chain rattle, its quite common - up until '95 when they finally fixed it.

    If its excessively loud, then it probably needs to be replaced (along with the tensioner).
