Um, not sure. I'm not a super Guru like most on this forum. Good with a wrench, a mechanic I am not.

There are some manuals you can download at the top and look at the test procedures there.

From your first photo just past the braided wire, look just behind that. There is a gap you can look in the gap between the frame and the header...its sitting right there. Seat needs to be off.

Cheers!
