Re: Knocking noise ?
Get the valve clearances checked.
Also, might be a cam shaft. Mine was doing the same, got it swapped out for a spare i had and the knocking stopped

Re: Knocking noise ?
It was valve clearances!
My inlet was set at 0.40 and my exhaust was 0.30 !
Not good, I've sorted it now and the knocking has stopped!

Re: Knocking noise ?
I have a similar knocking/tapping sound which increases with revs - it's quite loud.
I have been told it could be the tappets
Anyone got a guide on how to adjust them at all?
