Test Engine Assembly and Mockup

I had a little time this afternoon (after a nice birthday lunch) to assemble the "test engine." This engine uses the 3-speed auto clutch from a C100, but with a higher compression C110 piston and the bigger port aluminum C110 cylinder head. The cylinder barrel and rocker box assembly are shared between the C100 and C110.

And of course I couldn't wait to get it mocked-up in the frame, to check the fit of the exhaust and intake manifold/carb setup. As it turns out, the "right" side engine case is slightly different between the C110 and C100. The C100 has an extra buldge on the clutch side because of the automatic clutch mechanism. This buldge hits the exhaust pipe I built. Just enough so that the exhaust won't bolt on the swingarm bracket. I have a couple options, the easiest being to extend the exhaust bracket, but I'm fearful that might make it look funny if it starts to "run down hill" as it exits the back of the bike. I'll need to spend some more time fiddling with it. Hhhmm.
