Im getting a rattling noise at low revs just below 2k and im 99% sure it's coming from the airbox? anyone else had this noise, im thinking it may be the snorkel into the box moving about?

Try opening the airbox up and have a look under the filter; it might be gravel in the base of the box.

Yeah going to have a look tomorrow, even my mate who is a mechanic said it's the airbox making a noise, something must be loose, dont think there's gravel in there but you never know.
