I'm going to use the pic Scott already posted. If your on the left side of the bike facing it, where the bolt goes in this picture will be on the top left side of the throttle bodies. Near where the throttle cables hook in. You'll have to remove a little black plastic cover that keeps the grime out of the throttle cable bell crank. The bolt is difficult to see.
This is the cover, it's held on by (2) 8mm headed bolts.
The other one is in plain site.
The allen head screws in the rubber boot clamps are challenging to get to, especially the center one. Took me about 20 minutes to get the center one loose. I have a lot of patience. It comes in handy. The throttle bodies don't come out of the boots real easy either. You have to carefully pry them out. Take your time and be careful what you pry on. Lots of VERY delicate components in that area !
