Last night I skipped the Scotch, put on the Ipod and had at it.
I removed my "cheaper" rack, turn signals & fender eliminator brackets, all the bolts in the rear body shroud and then got to fight those two little under-seat bolts that hold on the rear plastic clamping plate. the usual tight quarters how the heck do I get a wrench on it battle
Once I got the body panel loose I rotated the front of the panel down and had a good idea -- I reached up and pulled the cable end.
Of course the seat popped of easy and I found my problem. The lock arm which attaches to the cable had come loose. That little 2-3 mm screw must have backed out so it's off to the hardware store for the 25 cent part that I will locktite the hell out of when I put it back on.
Being a member of the red suspenders gang I'm also going to rig up a hidden pull to go along with the factory seat lock "belt"
