engine started ticking

Hey folks, I was out riding yesterday and about half-way through a 45min ride the engine started ticking/clicking. It was a pretty sudden change too, not something that has been gradually getting louder. I can try to get a video of it but I'm not sure how clearly the sound of the ticking will come through. So what could this be? The valves or rockers? It sounds like it's coming from near the head/head cover but it's hard to tell. Is it safe to keep riding until fall/winter when I can rebuild the engine over the winter months or should I be more concerned about the issue? Thanks for any help and advice.

PS I have a '95 ZX-6E

cheers
matt

Depends on whats makin the noise.

But I would personally figure it out before I do any more riding.


A sound clip would give us a better idea of whats goin on.

Yes a sound clip would help..

Oil level?
Miles on bike.
Valves last checked when.

Oil level is good.
Bike odometer reads 85k miles (which I find hard to believe but that's what it says).
No idea when the valves were checked last.

Videos of the engine ticking:

Sure sounds like a valve ticking to me.

Since you don't have an idea when the last time was.
Sounds like this weekend will be it.

Does the sound go away for a bit if you rev it?

I had very similar ticking noise and turned out it was a cam chain tensioner.

Nope, the ticking remains just about as loud, but ticks faster when the rpms rev up.

So my only question is that, don't valve clearances slowly move out of spec? Whatever happened the other day seemed to happen rather suddenly. Ie, there was no audible ticking when I started riding, then as I was accelerating on the highway, I popped up to 13-14k rpms, changed gears, and then could clearly hear that the ticking had started.

In any case, sounds like I need to open up the engine.

Yes, they do move slowly.
As to why the sudden noise have NO idea.
Well the only idea I can think of is the valve is sticking in the guide.

That being said, the only thing I know to do is eliminate possibilities.
If all your valves come back in spec, we know what it's NOT. Would also pull the CCT and see how many click's out you are since your in the area.

That sucks.. so I guess it's probably the valve clearance

Working on Inline-4 is such a pain but this video will give you basic idea if you have never done it.
If you get a hold of Service Manual that would be a lot better too.

The fact that whatever it is happened suddenly makes it more alarming. If the valve clearance moved suddenly and radically out of spec, parts are more likely to be irreparably damaged. But you probably already guessed that...

As far as tearing into the engine and checking/setting valve clearances: is this a job that you are comfortable/have experience with? Please don't make things worse if you are in unfamiliar territory.

That being said....I look forward to seeing what you discover!

Why can't the bad things happen at the end of summer?

Went with Plan B:

Buy a 2007 zx6r and worry about fixing the 95 zx6 later this fall/winter.



WOOOO!!!!!
