Jeb, I'll tell ya, when I was putting together my "Frankenflyer Z" I had two almost complete Z's, an '85 and an '86. I set about building one good one from the bunch. I ended up using the '85 frame and swingarm with the '86 motor and Forks/trees with a bunch of other stuff mixed in. I only used the '85 frame because it was in much better shape than the '86. Now I swear at some point, I had both stripped frames together, side by side comparing them and their almost negligable little differences when I was trying to decide on which frame to use. I went over every little detail and I don't remember the head angle being any different - I usually notice little things like this. Darius, you just keep on posting those pictures of that beautiful Z project, no-one on here is going to complain about that - just take some different ones from time to time.
