Did I break something?

I rebuilt the carbs on my bike last night and today I've been trying to get it started so I've been cranking it a fair bit.

The last few times I've cranked it, it cranks for 2 or 3 seconds and then it sounds like the starter disengages and is just spinning. If you let off and crank it again, it does the same thing. What's going on?

If the battery is not fully charged, that will happen, if the battery is fully charged, then you may need a starter clutch rebuild kit.

Ah....no, the battery is on a charger, but it had seemed to be cranking fine earlier....guess I'll leave it alone for awhile.

Well crap, apparently my starter clutch is dead

Where can I get a rebuild kit for it?? I can't find one anywhere!

edit: Bike Bandit lists a "starter clutch assembly" for $100...ouch I'm guessing that's what I need, isn't it?

...perhaps?

"everywhere" includes z1, yes...
