Uh, one could always order the bolt through a dealer who will add it to their weekly order with no shipping charge.
I agree, especially since there is no need to rush back with the new bolt. I'd order it via dealer, and stash it with the stuff you use for servicing the bike.
You should also know that bolts have quality grades - you could make the right size and thread of bolt from plastic, but it would not
do the job there. Common hardware bolts are often Grade 3. Better bolts are Grade 8, and maybe up to Grade 12. The yield-strength of the steel used in better bolts (not the bolt, but the steel type) is astounding. I have no idea how the Japanese bolt standards go.
An unknown bolt that fits exactly still may not do the intended job. Just a thought. That said,
Internet Yellow Pages, not a wannabe) can find serious bolt dealers locally. Click the "business" tab and use the heading -

- Give that page a local ZIP code, and it will Sort the results by distance from you. HTH.
