I'm restoring a 1962 LI 125 series 3 and nearly have the engine stripped. I'm just a bit confused about the flywheel. I bought a standard flywheel holding tool with 2 cutaways one side and 3 the other but it doesn't fit my flywheel. My flywheel has "Filso Milano" printed in the casting and is made of aluminium and the dust cover is the 2 screws type. The flywheel has 1 large window and two smaller ones. I wasn't aware that the series 3 used a different flywheel? Any light that can be shed gratefully received. Also I guessing that in order to hold the flywheel I will have to either source an non-standard holding tool or take it somewhere to be "shocked" off with an impact gun?

Many thanks in advance.

I think the S3 used a variety of flywheels. You've probably got the most awkward. People must remove them though, so there has to be a way of doing it.

Ducati, Dansi and Filso all made flywheels / stators for the S2 / early S3.

Filso and Dansi are generally thought to be the best doorstops.

Now this might sound a bit of a bodge but"................in the past I have wrapped a rope around the circumference of the flywheel and held / stood on the end to hold. Do not hook the rope onto one of the flywheel fins.
This method might raise some comments but all I can say is it was suggested to me several years ago and has worked without any problems.

Thanks, I was seriously considering keeping this on 6v points but am rethinking this now since Filso doesn't seem a great system. With a bit of grinding and hacksaw action I reckon I can adapt the holding tool that I have and get the flywheel off and then set up a decent 12v electronic kit.

I have seen it done with a rope where the rope was woven through all the fins.

Also with a knotted rope in the spark plug.

If you take the top end off you can use a conrod holding tool to stop the crank (or an extension bar through the small end and a couple of blocks of wood if you're stuck).

I also have a homemade tool that uses two bolts mounted on a solid bar that can be used with care on most flywheels.

Do remember it's a left had thread
