Changing Spark Plugs NEED HELP
Still having problems removing removing throttle body, seems like the Emmisions valve is the only thing holding it on there, but there also might be another vaccum tube holding it down; Can we get some tips on how to remove the throttle body?
oh, I have a 93' GS300

We didn't see a bolt on the bottom of the TB. That's all it was for all of you who were losing sleep wondering, "Did the GS ever made it back on the streets?" Worry no more.
Here's some instructions I found which will tell you step-by-step how to get the TB off.

Once you have it off, the rest is easy. Just make sure you remember where the vaccum tubes go; you have to disconnect quite a few.
By the way, torque the spark plugs to 13ft/lbs. THat's not in the manual.

I just got done with mine. Had to do it just to put the valve cover gasket on the passenger side. Be careful in putting in the new TB gasket. I ripped it by not positioning it right. I also cleaned out the throttle body while, I was in there. It is a pain to do this not to mention tedious. This was on a SC 400 not a "93 GS?
