has anyone had any problems with there 07 zx6's? I have about 5000 miles and sometimes, when I shut the bike off and let it sit for a few minutes, it will not start back up. I was sitting on the bike the other day for about 20 mins. I made a noise like it just released all the fuel pressure or something. I went to start it up and it just kept turning over? Has anyone else had this problem? or am I the proud owner of the only lemon?
