Er........That oil leak in the 4th pic. Mine had one just like it and it was coming from the vertical cylinder exhaust cam bearing cover. The screw was loose.
If it was me and the roads were ice free I'd take her out and get her good and hot, come home and remove the fairing, stick her on the padock stand and let her sit at idle for 5 minutes and watch for the oil leak.Thanks for the link, Tricklidz. I'm currently reading the Clymer's manual for instructions on removing the heads and then the cylinders, with the ultimate goal of replacing the base cylinder head gasket. On both cylinders.
I'm worried about messing up the valve timing. And then figuring out how to adjust them again. Your blog has good notes, but do you happen to have a link to detailed procedures?
