Hi, I just bought a 2008 ninja 250r and it has 56000kms on it and about a half month ago I started to have a ticking noise coming from the middle of my engine and it only comes when my bike is idling at 1-3k rpms. I'm not sure if it's a cam chain problem or a valve clearance problem from what I've read. The sound also comes when I put the choke off and the bike is warm.

so even if you leave choke on once the bike is warm the noise doesn't come up till after? Last valve adjustment was done at the recommended interval? Sure its not louder on the right side where the cam chain is?

Your bike needs valve adjustment quite often so check that or have the valves properly adjusted if you are not sure.

It could be normal Kawi noise of course, but check those valves first!

The sound comes when the bike is warm and when the choke is off, it doesn't make the ticking noise after I fire it back up and until I rev the engine or start riding. I'll post a video as soon as I can.

Are you sure its nothing loose like a clamp that holds choke cable is loose, seems weird that the choke eliminates the noise.

Very likely the cam chain. Common on the 636's. There's lots of youtube videos on it. My son's was awful. At all times all conditions. The automatic adjuster sometimes doesnt work perfectly. You can get a screwdriver in it to push it one extra tooth. It;s been a while since we did it but there's also a video on how to do the simple fix. As easy as it is to fix I'd at least try it first. Contrary to popular belief Kawi valves rarely need adjustment. My son's bike has about the same miles as yours. Here's a video of the sound before & after

That may depend on the modal.

Absolutely, if I am not mistaken older Ninja 250Rs need valve clearance inspection every 10.000kms or 6.000 miles and the newer models every 7.500 miles.
