What is this engine noise? (Video to watch)

After I rev the engine there is a loud metalic noise that doesn't sound normal (but I'm new to mopeds).

What do you think it is?

Is it okay to drive?

(cut and paste this into youtube if the attachment doesn't work)

Thanks,

Clint

That doesn't sound right.

Re: What is this engine noise? (Video to watch)

Suggestions so far:

muffler baffle

bearings

Re: What is this engine noise? (Video to watch)

i'd have to agree with clint, it could have rattled loose over the years and it now just rattles.

Re: What is this engine noise? (Video to watch)

Sol, are you talking about the muffler baffle or the bearings?

Re: What is this engine noise? (Video to watch)

the bearings

Re: What is this engine noise? (Video to watch)

check for play, on all the bearings.

start with the most obvious ones like the wheels and move to the motor, grab the flywheel and try to move it.

First guess: Loose baffle or exhaust leak.

Second guess: a connecting rod bearing.

Quiet under load, noisy at idle...

connecting rod was my guess too, but I'm not sure about that

Re: What is this engine noise? (Video to watch)

From a cold start rev a little and move your hand all over the top end and tranny case to locate where the noise is coming from.

So am I feeling for the noise? So far it sounds like it's coming from the cylinder area. Is this where the connecting rod bearing is?

I'm so new to these engines that I hardly know what stuff is called. I am a fast learner and am willing.

Re: What is this engine noise? (Video to watch)

From what I've found, I bet it is the connecting rod bearing. I could take the cylinder apart to check, but I don't even know where to get new gaskets for puting it back together. There is hardly any mention of ITOM on the web.

People say that it maybe has a Franco Morini engine, but some say that it is a Minarelli.

Any help would be greatly appreciated! I can send pics of the engine.

Could be hitting the head gasket depending on the type (and if there is one)
