HELP DIAGNOSING SOUND! ninja 250

Hey guys I have a 2008 Kawasaki ninja 250r. Recently purchased it and I noticed it makes this sound when itís cold start itís like a clicking ticking sound some people have told me itís normal for Kawasaki motors, others have told me it needs oil change?
HELP please need help diagnosing the sound is it normal? Should I worry about it?

By the way the clicking goes away once itís warm and Iíve driven it for a few minutes

First video is the ticking sound, and second video is the bike warmed up and the sound went away

My first ZX14 did that for a few seconds upon starting and it was the cam chain tensioner.

I think you should get it in the shop and have a tech hear it.Cam chain rattles normally disappear as soon as the oil pressure rises.Virtually MAYBE about 10 seconds at the most.And it shouldn't repeat this sound once it's warmed up and stopping to shut off then starting again.This to me doesn't sound like a cam chain.I think it's something else,not that the tensioner isn't going bad or something.That could be as well.But this doesn't sound like a tensioner issue.To me anyway.I'd be more inclined to say Valves.Probably never been spec'd on this bike.Cold,they fit 'looser'(if they aren't adjusted right).Warm,they tighten up a bit.How about header leaks?Also sounds similar to this.I'm ruling out cam chain play.If you wanted to REALLY be sure before you open it up,you COULD buy an APE manual tensioner.Install that.Set it correctly(which is easy to do)and then see if it still is clicking like this.On my Kawasakis,the beginning cam chain noise does not sound like this.
I do have a manual one on my 14r,so I don't get any looseness at all at startup.My H2...I've NEVER heard any cam chain noise.Cold or warm.The APE tensioner is a good add-on regardless.

'sound goes away' tells me the motor parts are expanding.Normal.But something is not okay I think with what we're hearing.I'd be cautious about riding it till ya find out what's goin on...good luck...and WELCOME!

It may need an oil change...yes...but that won't cure something mechanical going wrong.Hope these posts help....in fact,you probably should change the oil...then look at what's in it.You may find some clues as to this sound.

It's NOT normal.When it warms up and the sound goes away...that's NOT correcting problem,unfortunately.It'll get worse till something snaps...that's my opinion.They can check the valves easy on your bike.Probably wouldn't cost too much either with that one.

Is it easy to get to the cam chain tensioner? I hear putting a manual one in there would correct it
