    Bike wont rev high and it has a rattle sound

    Hm bike fell over in carpark, only handle bars hit as far as im aware of but it wont rev past 10 easily so i dont take it past it
    wondering whats causing this?
    when the bikes idling there is a rattling sound, more of a rattle than a tick
    anyone have any idea whats up?
    bike is 88 fizzer250

    Is your bike the Exup model & could the valve be broken?
    Do you realise how many holes there could be if people would just take the time to take the dirt out of them?

    Sure FZR250s have cam belts? Most 250 sportbikes don't, which is why they can rev so hard from what I know

    Falling over shouldn't affect that. Perhaps you are only now noticing it as part of concern after it's topple??

    Could you have banged the airbox out of place?

    does it run on all four cylinders all the time
    if not then maybe you could have bumped a lead or maybe damaged a coil
    do a spark test on each cylinder and see what happens

    A vacuum slider may have become stuck - if you take the airbox off you should be able to see them. Check that they all move in and out freely.

    sounds like something has come loose in the exhaust/muffler, dropped across the main pipe, and is not allowing a free exhaust flow at higher rpm.

    Have you push the vacuum sliders up? Do they drop back down by them selves?
