Because they removed the airbox, i assumed they probably forgot to fit an air filter (BMC) so i checked yesterday. Hopefully everything was in place, only the top cylinder air funnel is moving and doesn't have an o-ring |
I would say that's your answer. Let's consider the facts...
"Oi...how did Lloyd Grossman get in here".
Aluminium type tinkling sound, coming from the front, only happens at certain revs, intake trumpet loose and without o-ring.
I would say it's the intake trumpet resonating at certain revs. Above or below those revs the induction frequency sort of keeps it pinned
