Sounds like zapping from grounding of coils. But idle sounds good. Very weird.

In case it is the timing chain, don't worry, it is a sound that will get worse with time but nothing will happen to the bike. Breaking a timing chain is very difficult.Howdy,
Started my 2015 650 XT a few days ago, and while it was idling, and I was putting on my gloves and helmet, I heard what might be described as a tapping or clicking sound. Here's a video (make sure the sound is not muted) in which you should be able to hear the relatively faint--but distinct--sound. Any idea what is causing that?
Last time I'd fired it up couldn't have been more than 3 weeks prior. It's riding just fine--same as always.Humm…more like a clicking sound to me. Puzzling for sure. When was the last time you fired it up?
Will do. I'll report back.My first thought too, plug wire arcing. Run it at night or in the garage with the lights off and see if you can see any blue sparks.
I will have to double check if the sound goes away after it's been running a while. I'll report back.Yes, can hear it ok. Its not affecting the tickover so my thinking is that its not electrical. Is it there when the bike is fully warmed up ?
Or run your hand along them while running. You'll find it for sure, then.✌😂Will do. I'll report back.
Personally I think it is a valve clearance sound on a valve that is on the upper end of the permitted clearance. Sometimes when oil has drained from the head, such valves can be noisier than normal on start up.I will have to double check if the sound goes away after it's been running a while. I'll report back.
I know there are several opinions about your problem. I am almost convinced it is the timing chain.... When a chain is loose, it makes the same noise, and it usually attenuates when hot.So here’s the latest: I started it up today, and didn’t hear the noise at all. I rode for about an hour and a half, then when I got home left it running and listened again, and still no noise. So I guess at this point, all I can do is keep an eye out….or I guess I should say an ear out…to see if it comes back. if it does, I’ll post an update.
