I found this:

I've had good luck getting individual stainless bolts from http://www.desmoparts.com/ High quality bolts, great selection too. He has kits for some bikes, but a separate page for individual sizes.

The local Ace Hardware has metric flange bolts but they are generic Chinese crap with poorly made threads and rough finishes--not something I trust to hold critical loads or look at and feel like ...

Turns out Honda's parts numbering system for bolts is readily decoded, and they use the same parts numbers for both motorcycles and cars. An 8x55 flange bolt is 95701-0805508. High quality Japanese-made, beautifully formed and spec'd. to meet the strength needed here. Call your nearest Honda car parts department, ask for that number, if they don't have it in stock they'll get it usually the next day. I paid about $1.25 per bolt, well worth it.

95701 = flange head bolt
08xxxxx = 8 mm dia.
xx055xx = 55 mm length
xxxxx08 = thread pitch??? (less certain about this...)

In reading this, I had some thoughts since I've had to deal with metric hardware in a sideline project making cam chain tensioners. If you did some digging might find the 8 is a rounded M8-.075 fine thread pitch. They do two fine pitches, M8-1.00 and M8-.075 threads per millimeter. But I'm guessing. The coarse 8mm thread is M8-1.25 threads per mm.

Here is a link to the ISO charts

I buy bolts at Fastenal, where they can be ordered individually (if not in stock and usually not). Problem is washers and nuts are not sold in singles. Just pointing out the alternative. I am fortunate in having a really good old style hardware store for the goofy or single stuff. I use Fastenal for my quantity purchases though.

Make sure you use anti-seize on them for sure when steel on stainless or stainless on stainless. I am not sure about aluminum. Seems when the bolts/nuts are threaded together the scraping of the surfaces causes some removal of a material that surfaces to avoid corrosion, then the material will bond together - aka sieze up. My brother used stainless for a nut/bolt pinch clamp on a Betor fork axle clamp. They seized and he had to snap the bolts to get them off.

I'd certainly check on the aluminum/stainless reaction to be sure. Here's Fastenal's take on it.

Here's another expert's take from an expert in the industry based on what I've found on a net search, Joe Greenslade.

The dual radiators is interesting!

Dual radiators, a great idea, dummy radiator guard??? Seems like another place for catching dirt & mud?

I run 87 mostly, every so often I splurge and put in 93. It runs exactly the same.

I would never pay anyone to do my fork seals.

I've used it to insulate luggage from exhaust heat.

Yes but then you would have to cut and match the complex curve angles of the tank area around the fuel pump intake. So much easier to reorder the tank heat shield that comes on the OEM tank and place that around the fuel pump. That is what I did; it fits quite nicely and it took about 5 minutes with the tank off prior to its first installation.
