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.

Bad? Need fixing?

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.

low oil possible? or yea valve clearance needs attention

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.

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

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...
