Camshaft noise on '86 700F

Hi am a new proud papa of a '86 vfr that had fairing damage, but was a strong runner in the test run....

The valves were adjusted and the mechanic could not quiet down the excessive engine noise. He said that it could be the cam is not getting enough oil and that I should look into the Hole Shot Racing cam oiler product.

Do any of the experienced wrenchers out there know anything about this?

I am also getting a wierd throttle response around 7000 rpm where the (camshaft?) noise is limiting effective acceleration.

Thanks for you help in advance,
