    I have a ratcheting noise comming from the engine (I think) when braking.
    It happens when I brake front and back, so when the nose dives it sounds like gravel in a tin can,
    Its not the brakes, I can't find where it comes from.
    Anybody any idea?

    let me clarify a little.
    If I come up to a trafficlight or something and I have to brake I hear the "grinding noise".
    It doesn't matter if I brake front or rear, it appears the when the engine it tilted forward it makes that noise.

    I hope this makes any sense (Not native english speaker)

    Check all the bolts that mount the engine to the frame but I do not think that is the problem.
    I don't think it is coming from the engine or related to the engine at all.
    Unless you are low on oil & when braking the oil is moving away from the oil pump pick up.
    Check your oil.

    You say "It's not the brakes"
    What have you checked?
    If the pads are worn then the noise could be metal to metal.
    Look for grooves in the brake rotors.

    It could also be a front wheel bearing going bad.
    Jack the bike up & spin the front wheel & listen for the sound.
    You may need to remove the brake calipers & shake the wheel to see looseness.

    I don't know if your bike has the linked brakes, if it does when you are applying the rear brake it is also applying the front brake.

    I've found it!
    Nobody is going to guess what it was.

    Thanks for the tips, i'll remember them for whenever I have to check something again.

    I'll post what is was tomorrow as soon as I've figured out what the names of some of the piece are ;-)

    After removing the playing card and some further inspection...
    It was the sprocket in the startermotor.
    The [insert offensive word here] idiot that sold me the "refurbished" starter didn't put the spring in thats pulls the sprocket back.
    So when I applied the brake the sprocket moved forward and lightly touched the chainwheel. :worried:


    edit:
    Just read in an other post the sprocket is called "drive spigot"
