Bloody awful metallic knock at idle

Ok, I know this is going to be bad.

When I leave the bike to warm up I can here a metallic knocking sound (pinking?). Its about 2 times a second, Its bloody worrying. Any suggestions?

Yerbs - very much like a bell. Anyone else get the same? As for the mirrors, yes. Oh well.

yep, pretty much the same. i posted a thread a couple of month back 'engine tapping' relating to that problem. check it out, you may find your answer amongst the replies.

I think the Bell Ringing type noise could be clutch related, as mine did it before a new clutch materialised on my bike. However, my bike developed an expensive sounding tapping noise (just like a dodgy tappet) from the rear cylinder head. Turned out to be a shagged woodruff key that locates in the camshaft to lock it to the cambelt pulley. In the process of self destruction it took the camshaft and pulley with it. I have been waiting since June for the necessary spare parts from the lovely Bologna factory. Isn't summer fun, without a bike?
