What engine do you have? If it's a Yam and the rattle is from the top end, think cam chain or small ends. Other options are valve clearances, and if it's smoking maybe a sticking valve or valve stem oil seals.

Does the rattle reduce or go away with the clutch lever in Gilo?
If so it could be a broken plate or spring, or the clutch nut coming loose. Or you may have just fooked the mains, lets hope not.
May be worth giving Rob Wilky a ring in the morning, he's a good lad and good with the yam engines.
