Fixed the stupid throttle

So, the problem with the throttle sticking open has been found and fixed.
The cause of the problem goes back to the round at Hampton Downs where the throttle was originally sticking. The throttle cable would slip out of the adjuster (similar to the pic below) when I opened the throttle and would then catch on the edge when I closed the throttle, causing the throttle bodies to stay open.
Because of where this is located (between the frame and engine) I couldn't see the bottom of the adjuster. When I fixed it at Hampton Downs I didn't realize that I had, in fact, just stopped it from moving but it wasn't located correctly. It was secured on the lip of the adjuster, not inside it. You would've thought that this would cause it to jam the throttles open, but because there was a bit of movement in the throttle tube on the handle bars it kept missing the throttle stop, allowing the throttles to close correctly. However, once things warmed up a bit the throttle tube would no longer clear the throttle stop. That, combined with the cable outer located incorrectly was causing the throttle to stick open.
All fixed up. The cables nicely oiled and the throttle bodies will get a clean and everything double triple checked.
EDIT well, it appears the clip that holds the cable into the adjuster is missing. That doesn't surprise me in the least ....
