Ticking noise from above engine?

I did a valve adjustment last summer and the bike was running great. During the off season I disassembled the carbs and cleaned them then did a carb sync.i synced then at 3k rpms. now when I run the bike at idle I notice a ticking sound coming from the engine. A friend told me the chain in the valve area might be lose. Maybe the valves tightened after the sync I don't know. I also did the FOG air box mod before syncing. i need help finding the culprit. I tried attached the audio clip but it's not working

Quite valves are a sure sign they're tight... you don't want quite.
A slightly metallic, rhythmic, overlapping ticking on the top end at valve cover is totally normal.

Now, if you have a Gen 1 and are still running the Gen 1 CCT, that may be the cause. The CCT (cam chain tensioner) on them is crap and should be swapped for a Gen 2... 1994-2009.
No modification needed. Just a direct swap.

Otherwise, the Gen 2 CCT is automatic. No adjustments needed.

You can check to see if the timing chain has stretched.
Remove valve cover and measure the length between 21 pins for a total over 20 links.
Standard length should be between 7.50-7.52 inches... 7 1/2"-7 17/64"
Wear limit is 7.61 inches... 7 5/8"

Camshaft chain 20-link length = standard 127mm-127.4mm (4.99999"-5.015738"), service limit = 128.9mm (5.074793") America should get on board with the metric system, IMO.

Jimmy Carter tried getting us onboard with metric system... You see well how that turned out.
We said.... "This is 'Murica... and we don' need no stinkin' metric system!"
Haha

I gave the OP Imperial measurements because he almost 100% doesn't have a metric tape measure or ruler. But pert near everyone here has a "normal" tape.

I think I remember you guys saying it should sound like a well like sewing machine. Lol. Over all it does. After the air box mod. The exhaust seems a little louder.i think it might be the weather. It's still 45ish degrees Fahrenheit here. It's a constant ticking and seems louder after warming up.

But you gave him the wrong specs.

Crap... yeah, you're right @bpe, I did...
Dammit, I gave him the primary chain's numbers.

5.075"
Basically a hair's width over 5" is the wear limit for timing chain.

More or less, yes. Sewing machine is close enough.

Airbox mod doesn't and should have a thing to do with the exhaust noise.
And honestly, you shouldn't really even hear it from the intake side, even when romping the go tube.

I dunno... cold or warm, mine sounds no different, it just has its normal Kawasaki straight twin noises... owned it for 12 years now. Since new.

When's the last time you changed the oil and what "weight" are you using?
I run Shell Rotella T 15w40 year 'round with no issues.

Average human hair diameter = .00388 inches. Brand new cam chains come with a 20 link length of aprox 5 inches and 2 hairs, + or minus 2.02 hairs. Service limit of 5 inches and 19.276546 hairs. If your hair is thinner or thicker than average, adjust accordingly.

As no one has seen fit to ask...OP, you might choose to add some pertinent information...year of motorbike, total mileage and mileage since your valve adjust and carb synch?

@ducatiman
I sorta mentioned it, the year anyway.... in my first reply...
Hoping the OP would take the hint and give up the info. Guess not.

Its incumbent upon any one seeking info to provide basic, pertinent bike info...year, mileage, service intervals..without being prodded. It just creates more back and forth wasted posts and time to be answered.

Answering in an intelligent manner, without that background information, can be difficult, misleading, or possibly lead to impertinent or incorrect info altogether.

Sorry about that. Been busy. The bike is 2007 , have little under 7k miles. Yes,ducatiman when I got the bike last year with 7k miles I changed the oil to Castrol synthetic 4t. Then swapped it with shell rotella per O.E.M. it shifts much better but that's when the ticking started I think

"Maybe the valves tightened after the sync I don't know."

No, not due to a synch (done correctly, more on that later, maybe)
Nor due to oil change Castrol to Rotella either.

But now at 7000 miles, you are right at a valve check interval (book calls for 7500)
Book also calls for an initial valve check at 600 (I'd submit this is never done)

Yup, time to pop the valve cover, check clearances
************************************************** *******************************
"did a carb sync.i synced then at 3k rpms. now when I run the bike at idle I notice a ticking sound coming from the engine."

synching at 3K inevitably throws the synch off at idle.

The "book" (service manual) calls for synch at idle. After your valve check, I'd urge you to re-synch at idle and see if there are any positive results.

I was able to get a friend to listen to the audio clip. He tells me" for sure your valves are making the noise. They are loose". Is that possible? I just did the adjustment 500 miles ago.

Does your buddy routinely work on EXs? He may not know how it's supposed to sound.
I'm telling you, a super quiet valve train on these bikes is not what you want to hear... nor should it be horrendously noisy.
It's SUPPOSED to have a slight, overlapping, rhythmic metallic sound coming from the valve cover. Loud enough you should easily hear it at idle.
During routine use, the valve lash tightens up due to wear... it gets quieter.

Are you 100% sure your clearances are correct?
The intakes should be set at 0.006 inches and the exhausts should be set at 0.009 inches.

O_E_M

ETA: The only real way the lash would loosen up is if you didn't get your lock nuts tightened enough and the adjusters have backed out.
Too tight where the valves are quiet and the bike will be hard to start because the valves aren't closing fully... which will burn the valves.
Too loose and and it won't run well and be very noisy.
But properly set valves WILL have some noise.

I do have a hard time starting. It won't start without a 1 minute choke.

Then I suggest, in this order....
Pop the valve cover and recheck your lash.
Reset your sync.
Make sure your mixture is set properly.

Go to tools... Wiki.... at second part of section 5 is Carburetor...
Cleaning... scroll down to TASK 9.1
My write up for dialing in mix.
