In article <38199776.B5872FDDnopsamrus.ca>, rhusseynopsamrus.ca says... I had a similar noise on my 87 Turbo 900.....the timing chain was stretched and the rubber chain "guide" mounted on the underside of the valve cover was as hard as a rock. What you are hearing is the chain hitting that rubber. Replace the rubber and the chain and be sure to inspect the tensioner to make sure it is working properly and "reset" before installing the chain.
