i have an 09 600rr and sometimes it wont start. I can push start it and next time it starts right up so I dont think its the battery. Seems like it may be losing ground? Wired are tight on the battery. Where does the ground wire connect to the chassis on these? I'm assuming one wire goes to the starter and the other to the frame but I can't seem to locate it.

 

If you remove the gas tank cover, and follow the wires from the batter that go towards under the tank, there are some wires that are ground to the frame under that lil rubber flap
