NOT MY PICTURE

That is the starting and charging system.

Since the starter has no bendix, there is a Sprag clutch that allows the starter to be engaged and disengaged etc. Also has something to do with the charging system since that round housing, which the sprag is inside, goes around the stator and spins creating electricity. Anyway this is the part that is suspect in my starting issue. Unfortunately to buy all the parts there that are usually replaced together is far far more than I am willing to spend. So I ordered the $15 flywheel puller tool to take everything apart and inspect it all and then replace what is broken.... I really hate this bike. I want to sell it and buy something else. I have it up for $2200 broken on CL. No bits, not even scams.

Stupid Central Coast

That electromagnet though. As an EE that thing is sexy.

Stator coil? Pretty pieces of windings for sure.

You are correct. On closer inspection that would be a stator.

The machines used to wind coils are amazing pieces of kit...

The good thing about these types of components is that they are generally pretty robust, and the guts look pretty good. Have you checked wiring? Is there a regulator unit? Is the starter solenoid sticking? Are the connectors good in the charging system?

That being said I seem to recall there was an issue with bad Aprilia stators back in the day, but I think it’s only up to a certain year...

Oh no while the stator and rectifier do have italian wiring issues from the factory, it is making “the noise ” that indicates a bad Sprag.

I should get the upgraded stator while I am in there... We shall see once I pull it all apart

Yeah a weak signal from the starter relay because you’ve got high resistance in the wiring/connectors can also cause issues (partial engagement, then things get jammed up). Worth checking quickly even if the sprag is toast because it can make the sprag toast again quickly.
