IT does this rattling noise once it is warmed up and at a certain rpm anyone know what it is? Valves are adjusted

Heres a video

Does noone know? I don't mind fixing it just would like ideas on what it could be.

Lousy speaker on my tablet so hard to tell. You say valves are adjusted but are you sure it was done right?

It sounds normal to me. All I heard is the normal taping of the valves.

Yes they will be a little noisy. What do you have them set at. I have mine set at .002" intake and .003" exhaust.

You will be good at that. When you stop hearing the tapping you will know it's time to adjust valves.

Is there a place to buy crankshafts for these engines in the event that something does go wrong it seems to be the only part I cant find?

You can usually find them on Ebay, Taobao.com and here. http://www.motopartsmax.com/index.ph...21/eID/8/tID/2
Just have to check measurements to make sure you are getting the right parts.
