What stands out is the modified flywheel/ignition cover. It exposes the countershaft sprocket making it easier to swap sprockets and keep the area clean of mud and crud. So I'm thinking of doing something along those lines.
The flywheel/ignition cover is pretty trashed on my bike. Not only has the ignition cover been welded on, but there's another weld in the area that covers the sprocket. It looks like a fairly easy mod that can be done with a poor-mans mill (hacksaw and dremel).
Shouldn't take more than a couple hours.
