hey guys, i have these mounts too and must give dave a big congrats for the wonderful info in this thread.
i ran into the same problems regarding fitment with the charcoal canister. a few emails back and forth with phil @ bsh about how to solve the issues and he finally directed me here.
dave, just wondering if you ever got a pic of the "stay" you manufactured to connect the canister to the fender strap?
also wondering if you remember the length of the "stud connector" that you used? i've been having the most ridiculous time trying to find these but finally had some luck with a fastener specialist, though the smallest they had was 20mm and i'm not sure whether it is the right size...
cheers,
steve
