So it looks like I didn't tighten the aforementioned bolt to spec when I put my bike back together. It has since left the building. Without being able to apply choke, I can't even get the bike to start today. Stripped it all back down, and I can see that the bracket is loose because the bolt is missing. My problem is, looking in the service manual, I can't seem to find a description of the bolt itself, ie, what size it is\what threading etc. So I've no idea how to go about buying a replacement short of picking up a handful of metric bolts at random. I was hoping someone could direct me to one of those sites that breaks down parts in detail for ordering, or maybe someone just knows what size it is.

Another lesson in CHECK EVERYTHING as you reassemble

EDIT>It's not a bolt, it's a 6mm flange nut, and apparently, I'm missing both. Zero idea how I screwed that one up. Here's hoping the local hardware store carries 6mm flange nuts...

 

Ronayers.com is where I normally order my factory replacement parts. There is a fiche that you can probably find the bolt on
