Question Weirdest Engine Sound

Hey guys and girls! I have been a member of this forum for a while and really enjoy reading all of the posts. I have finally managed to purchase myself a KLR. There is however a slight problem, there is the weirdest sound coming from the top of the engine.

I have uploaded the sound to youtube, the URL is /watch?v=zK6b1SyaahA (Sorry cant post links yet but you can copy and paste that after .com in utube) And no there is not a problem with the video that is the sound the bike makes! I would really appreciate it if anybody here could maybe help diagnose the problem or point out a solution if they have encountered it themselves.

The bike was recently serviced and has enough oil in it. The bike starts fine but after say a minute that sound comes. Like when it is warm.....

It is a 2006 KLR.

Thank you very much, all the way from South Africa!

Sounds to me like a dry journal bearing.

lloydb, I can not tell much from the sound clip. Is the exhaust header heat shield loose & jingling?

But one can easily check for oil flow to the cylinder head camshaft bearings by loosening the top banjo bolt of the oil pipe, near the fuel valve and carburetor enrichener cable, maybe a 1/4 turn loose. When my engine is started it usually has oil flow to cylinder head in about 5 seconds.

Of course this will not confirm the actual condition of the camshaft bearings from any past sins of the previous owner.

Modify at "YOUR OWN RISK"!
