1200GSA rattle

Hi, I need some advice, i have a 1200gsa and in the last week i have noticed under full throttle in top gear i am getting a lot of rattling and tapping. Is this normal or should i get it looked at .

Hi mate, you might get a better response if you posted this in the right section

While i'm here though, mine did that, at low speeds under load, sounds like pinking. Try it on 97/8 octane, see if it cures it, worked for mine!
