After installing pressure fed tensioners on my 82SC, I have noticed a constant loud whirring sound from the engine.

I have read other posts of this phenomenon and I am wondering if this is someting to be concerned about.

To characterize the volume of the whiring, with the stock muffler you could not hear the exhaust note over the whirring. With a dual out Dansk, under light/medium throttle, the whiring and exhaust are about the same level.

I am considering pulling the cam covers and examining chain tension. Is it possible for the chain to be too tight?

Thank you,
