Bloody awful metallic knock at idle

10-09-2004, 02:48 PM

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?

almost like a bell sound? Ive always had that on mine.................help!! btw these ar mh mirrors are these the ones? if so poss a bit long for my tastes

10-09-2004, 03:01 PM

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

10-09-2004, 04:54 PM

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.
mine is an m600 from 95.

Similar year, similar "characteristic" then

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?

i am not sure about the clutch, from what i gathered, we dont have the dry clutch, which is prone to be noisy... how long did your engine last before you had to strip it ? I've had the tapping noise for as long as i've had the bike (i.e. 1500miles)

I noticed a metallic ringing from my M600 the other day.....

...turned out to be the right hand pillion peg vibrating!

Might be worth checking.

My steed has done 32k from memory, but I haven't seen it for so long, I can't remember what shade of dirty it is now.

Easy to see if its the clutch, just pull the lever in and see if it goes away.

Another common problem is the flywheel nut coming loose, which gives a knocking noise at tickover and will trash the crankshaft

Piston slap from a partial seizure....sory don't shoot the messenger :lol:

only if the messanger is grinning.

Bloody Hell!!!! Space, Berto and Garry, cheers - now I feel sick!!

Ok so cerebus lets discount the obvious first - My footpeg was vibrating too, funnily enough on the same side, but I'd never counted that as it was a different sound - it was pretty easy to trace. I haven't tried the clutch, but tis true - I don't notice it once I'm away.

The noise seems to coencide (sp) with the throb of the engine. Oh bugger.

It's just Ducati Monster 'character'.

Got mine a year and a half ago and was worried about the noise then, sounds very like the one you describe anyway, 18 months and 12,000 miles later it's still doing it so I put it down to that.
