Replacing Speed Sensor

I just wanted to ask a quick question on how difficult it is to replace the output speed sensor? I searched this forum and found nothing on it. Thanks.

if you are talking about the one located in the middle of your rear motor mount (or the braket to be exact) ,it shouldn't be a biggie. just find a way to reach, if im not wrong should be a 10 mm nut or something small like that...i think a single bolt, nothing spesial...

Cool...thank you.
