Okay, since I Know everyone has been dying for an update, here's what's happening with my discount MotoFizz bag that was missing a mounting strap.
I ordered a buckle and 1" nylon strapping from a cool place in Missouri:
clicky!
Edit: whoops, guess I already clicky'd them earlier.
Also got a replacement zipper for my mesh pants and some black shock cord to replace the loud yellow one on the MotoFizz bag. Very quality items at very reasonable prices, small custom quantities are no problem. Got my order in 3 days over a holiday weekend. A satisfied customer - no other affiliation.
That's pretty cool, but here's the good news. I was looking at the instruction cardboard(?) that came with the MotoFizz bag. Japanese all over the place, and pics of how to attach, etc. On the whole chunk of cardboard the only English is a website address. So I went to the website and again, lots of Japanese and pictures, but this time no English anywhere...so I start rolling my mouse and finding the links. Finally found one that fired up an outgoing email to sales....
So I send an email explaining about the missing strap, they responded in not perfect English a couple of days later, and the jist is they are sending a replacement to me free of charge! How cool is that?! The "exclusive American Dealer" of MotoFizz stuff could not be bothered with helping me find a strap that would work, even though they also sell straps. Went to the source, and they would love to help. Great product service.
So I'll try the stock straps as soon as my bike is street-able and trip-able again. I'll also be on the lookout for some ratchet straps because I worry that the stock straps may slip under speed, vibration.
