    New cam chain and tensioner. I think they are $80 each from memory, so about $250 fitted to the bike by a mechanic .

    where opinion holds more weight than fact.

    It's better to not pass and know that you could have than to pass and find out that you can't. Wait for the straight.

    mite find it's a bit more than that my chain was $115 by itself.
    mine hase done 46k and got rattely because of the chain AND tensioner
    otherwise it could be the lifters need re shiming but I dont think so at those kays
    should not need a rebuild unless the compretion is down or smoking

    From experience the ZXR250C had a slight problem where the cam chain touched the top of the rocker cover (easily seen when you have it off)

    The may well be "witness" marks where the chain touches, and after a few K's the chain (even though it's new) quite often will touch again.

    I used to "relieve" that area with a Dremel and never had a problem after that.

    I guess I have fitted about 30 cam chains to ZXR250's over the years.

    you have to split the chain and rivit it back together

    so if you can do that its easy
    just pull the cams out and make sure they go back together in the right place

    there is a thread on her somewhere about it
    find it and read it

    it isn't hard but make sure you read it first and follow instructions
    cam and crank have to be lined up before you pull it all apart
    also you need to count the number of links between cams

    the hardest part I found was splitting the chain
    maby aftermarket chains have a link in which case it's a lot easier
