Is there an ideal location to mount these, and i imagine they should be mounted as upright as possible.
You could do that or I have seen some people fab a small aluminum bracket that attaches to the headlight mounts and you then attach the BAS to that bracket.
What kind of bike? On my 05 600RR the was two perfect spots on the fairing stay that I drilled and mounted mine. Almost like thats what the spots were for.
Yep... all the 03-06 600RR's can be done that way. Here's some more detailed pics & descriptions. http://www.cbr600rr.com/forum/index.php/topic,19651.0.html
