Scottly wanted me to post this here regarding the successful repair of my starter clutch due to a bad spring, so here it is:
I am very happy to report that the through-the bottom starter clutch fix I performed on my bike went successfully! All in all it takes about two hours to get everything off and out, and another two hours to get everything back in - but Yes, it can be done! Here's the before and after videos:

No more Scary Noises!
