The harmonic balancer keeps the crank from self destructing at high RPMs. If you are certain there is no chance that it skipped a tooth while you were working on it, then there shouldn't be a problem. The only way I know to verify it is to pull the flywheel and see if the dots on the gears line up. I honestly don't know if just one tooth off would be that big of a problem. But nevertheless, if you ever have to pull the flywheel again, you should check it.
The failure mode of a harmonic balancer is the crankshaft snaps in two after running for a while. Based on what you have said, I don't think you will have a problem with it because it sounds like you were careful not to let the gears un-mesh.

I thought about JB welding the piece back on the case, but the reason i didn't is that if it ends up vibrating lose or breaking off again, it's going to cause alot more damage being in there and floating around then if it's broken off and wasn't there at all. I didn't realize the cases were that cheap. If I ever have to strip it back down again, i'll splurge and replace it then.
ohhh yeah if the gears are meshed together for the harmonic balancer and the crank, i really don't think i lifted it far enough up to unmesh them. I just wasn't sure what you meant when you said misalign them. it was literally a couple of milimeters that i lifted the crank, just the thickness of the chain, in order to slide the old one out and the new one in. i didn't know about that ahead of time but i just figured it would be better not to disturb the crankshaft too much anyways. it seems like my intuition paid off.....hopefully. But since I haven't put the fairings back on yet, it wouldn't be too hard to take the case cover and the flywheel off to double check, it would certainly be a simple task just for the peace of mind it would bring. Have you ever seen pictures or heard of that happening before from anyone on the forum? I'm curious as to how many miles of running with the crank and the harmonic balancer misaligned would the crank actually snap? a few rotations of the crank? couple miles? 50 miles? Just curious.....
