Pucky, for the sv it's as simple as loosening a bolt flipping the linkage, tightening and wham race style shifting. Only problem is when you shift the wrong way and peg the hell out of the rev limiter.
When I brought my SV in for it's first service the tech guys did that to me to screw with me. However, if you get the lower fairings, you have to actually cut them to get it to work. Mine will remain uncut.
