tappity engine



my engine is a bit tappity - it's not particularly loud and only does it at certain idling speeds.

In fact it completely disappears when press the throttle

I've been told that this is normal due to chain & not belt

But could this have anything to do with smokey engine???

Also on a more petty note
my parcel shelf rattles all the time and drives me crazy - so much so i've taken it out which is a shame as it has speakers fitted in (the weight of the speakers is causing it to bounce)

Dose anyone know a modification to stop it rattling?

I'v fitted some new rubbers on the tail gate to hold it down but this doesn't help - the rattling seems to come from the flappy bits at the sides????
