Old starter clutch gear - 80 teeth
New starter clutch gear - 73 teeth
While not certain, I would have to suspect they sent you the wrong part.
The change in gear size would require a change in location of the pinion gear.
And I don't think the parts fishe would indicate it's possible by striking out the old p/n and listing the new next to it.
One thing to note is that 12600-24831 is a generic p/n rather than a bike specific p/n.
I've noticed in the bay of fleas, that quite often burgman parts are captured in my search net.
