    03 CBR600RR ticking

    My bike is ticking. When it idles there is a kinda ticking noise. And when I rev it the ticking noise goes faster. Any Ideas what it could be?

    Possibly just noisy injectors.

    Depends. Has it always sounded like that or has it got noticeably worse?

    I have known of an injector tip dropping out and rooting the piston and combustion chamber but on the other hand it's not unusual to hear a light ticking sound from injectors.

    (And besides, it may not be noise from the injectors).

    The other thing that ticks in time with engine speed is a cam follower with excessive clearance.
    ... and that's what I think.

    Or summat.


    Or maybe not...

    Sounds like a header pipe leaking to me , try tightening the nuts a tad to see if that helps .


    If that isnt it then feel free to consider doomsday theories.

    Time to get a louder can. That will solve it. (Providing it ain't a 'real' problem). My CBR thou ticked at idle and sped up with revs. A mechanic mate who I rate as very good said he would be disappointed if he didn't hear 'things', after all, there is a lot of metal flying about inside your engine.

    You should hear my RSVR with an empty tank & Magnesium rocker covers scary . Maybe look at a shim check just to be on the safe side ?

    My new R6 ticks like a mofo. Just wear earplugs and it stops.
    Ride fast or be last.

    Where is the noise coming from?
    Top or bottom...
    i had a cam chain tensioner come adrift on me once...
    sounded horrible when stopped at the lights.
    Dunno........... just a thought
    And that is the honest truth your honour..

    Not familiar with the engine myself but....to rule in or out the injectors un plug 1 and start, noise go away? no then stop engine plug back in and unplug the next and start.

    If not an injector, on a stone cold engine, spray a little detergent on where the exhaust headers join the head. Start and look for bubbles before pipes warm up...be quick.

    Failing that, start engine and using a long screw driver as a stethyscope..(spelling) try and identify the location the sound is coming from.

    Is it engine speed...bottom end, or half engine speed, top end...
