My brother just bought a 2013 636. The bike was already set up for track and it came with a quick shifter and GP shift. I have not seen the bike yet and won't til I get to NJMP this weekend. Is it an easy change to make back to standard? I know on most bikes it is a easy as fliping the knuckle on the shift rod. Is it the same on the 636. Does the quick shifter get in the way of making the swap. neither of us have ever run with a quick shifter and I don't really know with out seeing it if it would effect the swap back to standard.
