Loud ticking sound CBR600F4i

[Itchy]

CBR600F4i 2002. No mods other than suspension and stainless exhaust pipes.

Haven't ridden it for a few weeks.

I did however change the oil.




I can't work out what it is.

Is the exhaust blowing?
Clutch rattle? (Honda it's a given).
Cam chain?
Valves need adjustment?

I'd rather find out what the problem is get the bits then fix it rather than take it apart to find out the problem.



Thanks

Before I listened to it, I thought, "CBR600, gotta be cam chain"
Having listened to it, is it the twin cylinder version?
Exhaust blow is what I'm thinking now.

Where does the sound come from? Side, front, top, bottom, back of engine?

Cam chain tensioner noise is much more metallic and more of a rattle than a tap. The typical clutch basket noise isn't tappy either, more of a low level rattle that goes when you pull in the clutch and comes from under the clutch side.

It sounds like a blowing exhaust to me which should be fairly easy to find by feeling and listening for leaks, mine sounded dreadful when a header stud came loose. Does the bike run well?

Found it.

Cylinder 1 the nuts on the collar had come loose.

One was completely missing and the other side was loose.

So it's just a case of tightening those nuts and thread locking them right

Does it even run on all 4 cylinders? I do agree with the exhaust leak, but even then, it does sound rough.

I did up the nut.

There is significantly less noise.

What is worrying however is almost ALL the nuts were loose.

So I guess at the weekend it will be a case of a radiator removal and sticking in some new copper crush washers and thread locking them as the danger (I hope) of the studs snapping is greatly diminished if I can undo the nuts with my fingers.
