Removing the starter/flywheel disc?

Hi, i want to remove the starter motor disc (not sure what the technical word is for it) attached to the flywheel, as i don't want the starter motor and want to fit the smaller non-starter motor cover, but i'm pretty sure that there is a problem if you simply drill out the rivets with the flywheel breaking up.

Can anyone tell me the correct method of removing it so i can tell my engineer exactly what to do?

Thanks

Hi, you could swop with someone who wants a rotor with a starter drum?
The best way to remove the drum is to have an engineering shop cut it off in a lathe and it's not a big job; as you say best to leave the rivets well alone.
I had a chewed up starter drum removed by this method years ago and no problems,
good luck, Ian

Noooo!

You can't fit an earlier, non-starter flywheel to a later, starter equipped motor.

The earlier flywheel touches the later alternator as you tighten the flywheel bolt, allowing *a lot* of the smoke to escape from the wiring.

Here's how I found out: http://www.realclassic.co.uk/morini06051101.html

Actually, you can and I have been for 10 years!

Is is too close for comfort and can short out like Martin's did, it all depends on the particular flywheel/stator combination.

The later style diecast flywheel was made in both starter and non starter versions.

Hi again, I've had no problems swopping rotors over the years on 500/501 Morinis, yet they have all been post 1978 and it matters not wheter they are 6v/12v or have the starter drum fitted.
The only difference I've noted is that the 500 camels have lighter rotors (flywheels) than the road bikes.
We've gone a bit off thread but it's good to know there may be a problem when mixing early and later alternator parts.
We're always learning, good luck, Ian
