I am putting on a Bazzaz QS4 stand alone quick shifter onto my 2011 ZX10R and I ran into some mounting issues. The lead for the sensitivity adjustor is very short. So finding a place to mount it where it is accessible is very difficult. I was gonna mount it under the tank but then Its hard to get to it for any adjustment. Unless its a set it and forget it thing in which case it wouldn't matter where it was, I might be able to squeeze it in above the countershaft sprocket since I will be having the cover off. Im just not sure how delicate this thing is to being exposed to elements like that (wind, moisture, dirt, etc). Anyone put one of the these on your bikes?
