Starter clutch tool thread size

Hey everyone, I'm working on the starter clutch for my '83 CB1100F. I've already got the David Silver rebuild kit in hand, but now I need to pull the rotor to get to the clutch housing.

Can someone confirm the exact tool and thread size needed to pull the rotor?
From what I've found, it looks like I need an M20 x 1.5 Right-Hand Thread puller (like the Motion Pro 08-0085). Is that the correct one for the 1100F?
Thanks for the help!

The starter clutch is not behind the rotor on a CB1100F
its on the opposite side of the engine
just make sure you hold the 24mm hex on the ATU unit with a spanner before loosening the 12mm hex bolt

That package information is not for a 79-83 Honda DOHC motorcycle.

You don't pull a rotor to get at the starter clutch on a DOHC Honda, it's under the left engine cover. It's fastened with 3 bolts,
and doesn't look anything like the pictures you posted.

The Honda Shop Manual for the 1100F is in the Technical Documents section of the forum.
