2004 Vulcan 750: Can't shift into 2nd gear
2004 Kawasaki Vulcan 750
What I did:
Parked the bike behind my car, and then promptly backed into it the next day, knocking it over onto it's left side (go ahead and laugh, yes, it was stupid, and I even knew it was a bad idea to park it behind my car when I did it). I didn't see any visible damage at first.
The bike no longer shifts into second gear. It'll shift into first, and then back into neutral. I noticed that the clutch cable was a little loose, so I tightened it up using the locknut near the handlebar. That doesn't appear to have anything to do with the shifting problem. The clutch appears to work, in that I can shift into first and then drive the motorcycle.
I've read elsewhere that it's possible that I broke the shift lever shaft (runs from the external shift mechanism into the crankcase. However, when inspecting the external shift mechanism, nothing appears to be amiss.
If you had this problem, where would you look first? Is there any thing I should check visually or mechanically? Should I even bother checking the clutch, or does this sound like a transmission problem?
Thanks for any and all advice!
