I thought crap like that only happend to me....
Sorry to hear about your clip. At least you'll get to inspect everything. I remind myself when I make mistakes like this. This is why the pros are pros. I enjoy tinkering but I'd have surely lost my cool over that one.
I like the idea of using Yamaha parts where you can.
We are lucky to have experts here like Spud and Weld.
I'm interested to hear what was causing the problem. Like I said I gave up on mine when I discovered you can't remove the head in situ.
