If its a big "clack" type noise coming from the front cylinder as you turn the motor by hand it is normal. No idea what it actually is. Kind of freaked me out the first time.....

Is it accompanied by flickering oil light? = low oil pressure to tensioner
If not check cam chain and tensioner.

it is happening while the covers are off and im rolling the motor over by hand. been assured by locals that its normal.....

Yeah, it's when the cam just turn by the top of the lobe and the valve spring push the cam up until the chain slack is taken.

Don't know if what I wrote is understandable though.
