So the last couple of rides I've done at highway speed have been rather shaky. It really felt like an engine vibration, so I checked some things to see if one cylinder was missing, float levels uneven, anything that would unbalance the engine. Couldn't find anything. Just so happened to bump the front wheel and heard a noise. Got to inspecting and there was play in the triple tree. But it gets better...
I take off the handlebar brace and move the handlebars out of the way, only to find the top bolt almost completely screwed out. Said a prayer, adjusted the locknuts, and torqued everything back down. Went for a 40mi ride and all is well - the ride is a lot smoother at speed. Phew.
