    Hey all,

    Just installed a smaller front sprocket on my '02 R6.. Now when im
    travelling along (with the clutch pulled in, or when coming to a stop) the
    bike sounds like a bucket of bolts in a washing machine. :) Same chain, and
    same back sprocket. Does the sprocket have to bed in or something?

    Ermm, no. My troll meter is jumping, but assuming you're serious, no,
    sprockets don't need to bed in.

    I would guess either of

    a) your chain is worn and isn't coping with the decreased diameter it
    needs to bend to

    b) your chain isn't properly adjusted (clutch in reduces the tension on
    the top side because the engine isn't pulling it forward also see below)

    c) the new cog is causing the chain to have clearance issues or issues
    with the angle it's passing over the swingarm (usually only happens with
    larger cog though)

    It's your speedo. You'll need to calibrate it

    Oh okay, i knew it would be out now that ive changed the sprocket, but why
    would that make a noise?

    Yes, you need to bed it in , and in a low humidity and zero UV-light
    environment such as a tunnel.

    This must also be done at high speed so some 200kph plus runs through any
    one of the generously provided-for tuinnels around Sydney should do it.

    Ideally you need to minimise speedo calibration errors so the running-in
    program shoudl be carried out on the back wheel.
