Hey guys, my bikes been down for a while and after my latest attempt to fix it failed, I nearly gave up on it. I didn't really want to do that so I figured I would come to you learned folks to try and get some clarity.
It all started with a noise. Turned it on one day, and there it was. Sounded like the starter motor just kept running. Tap the solenoid, they said, so I did. The noise didn't go away. It got to the point that I figured if something was wrong, it can't be wrong if it's not in the bike. I switched out the starter motor (Which was looking pretty rough anyways), and the solenoid, but the noise is still there.
I found a hole underneath the starter motor, which can't be good, marked in the photo with an arrow, as if you couldn't see it. The guys who had the bike before me didn't treat her right, so I've been dealing with a lot.

Like I said, it sounded like the starter motor keeps running, but it's kind of an almost grinding sound. I really don't want to throw in the towel on this bike, but I'm kinda lost as to what course of action to follow. Any ideas?
