MZB oil seal cam
it is just a oil seal plug for the back of the old mag that was removed and I dont think you have to remove it to remove the timing case cover and also to remove the camshaft
A puller bolt wont work as their are no threads inside of it like the magneto
After removing the bolt a little heat and it should come off

I realize that something
I'm guessing that this single rotor he has installed is the 12v generator/alternator and ignition system combined. There is a pickup on the outside of the rotor that senses when a small spot spins around each revolution which ends up being the timing side of things.

BMZ mag rotor removal tool
To disengage your new rotor again, you will need a puller M27x1,25 (part-no.: 99 99 799 00 -Not provided!-).
If you have this then maybe you just need a bolt
I can measure mine if needed

Tommy - Thanks. My friend is
Thanks. My friend is supposed to check his instructions for the rotor. What does the big black nut screw into? We removed the existing bolt holding the rotor in place...strangely, there must have been 6-7 flat washers under the head of the bolt...probably just to take up extra space. I don't remember looking carefully enough to see what was exposed by the washers, but I don't remember seeing a larger threaded area.

MBZ rotor puller tool
as Jambo states to you need to remove the rotor to get the proper timing
Joe Ropose included this puller setup when I bought this when he was the importer for MZB
You most likely need to reposition the rotor a few times after reinstalling it to get the timing correct as it is not keyed to the crankshaft and the timing pickup is not adjustable
But once set no more adjustments for you timing
You can get this from Vape for about 12.00 US dollars not sure shipping costs
If you need one sooner I could loan mine to you but you must source one for further use

the big black nut
It is noted in the instructions that dont use any other means as the magnets inside may become dislodged
I tried this on a snowmobile rotor with a puller and stopped as I was using too much force with the gear puller so I decided to give it a little shock with a hammer I did get it removed but had to replace the rotor as some of the magnets inside did fall off
Here are the installation instructions posted for the MZB setup
