[CipiVTS]

Hi all,

Could the more experienced guys post some info / description of different engine noises for a 916/748?

How does a piston slap differ from the rockers knock or the main bearings gone noise? What other symptoms appear with the noises and can facilitate the identification of the problem?

I noticed on my 916 a strange knoking sound at around 4000-6000 rpm. It can only be heard while riding and when you accelerate and the rev is around 4000-6000.. I tried to hear the noise while idle, but i couldn't hear it/distinguish it.

thanx

In my humble opinion the Ducati engine is so mechanically noisy anyhow what with the dry clutch and the big exhaust that its very difficult to hear noises that shouldn't be there.

Does the noise go away when you pull the clutch in?

Worn mains make a rumble (well on cars they do anyhow!) DUcatis have roller mains so maybe different. Could it be bodywork or exhaust resonating?

Noise can only be heard while accelerating, if you keep the revs constant or pull the clutch it cannot be distinguished from the exhaust or other loud noises

Dont worry about it till it drops off

The only thing i'm worried is what if it's the rockers and i can still do something.
From what i understood rockers have a lighter metallic sound?

For the others... God knows

It won't be the rockers.

Blowing exhaust perhaps.
