While cleaning up after a ride today, I noticed a screw on the gas pedal. It seems to be a governor of some sort. Looks to be set so that you don't have full thottle! Could that be what it is?  Any ideas?

It may be the throttle pedal nut you're talking about?

The screw I was referring to was the onr just to the left @ (9 oclock) of the one that is shown in the pic!

I think you are looking at the free play adj. It stops the pedal so you don't get too much play in the cable.  the top one is throttle stop. If you want to know for sure, just push the pedal all the way down and the screw that hits a stop is your throttle stop. You should be able to readjust it to stop just before the tab on the throttle body hits it's limit. I was able to get the throttle to open a little bit more by readjusting it.

Ohhhh! Thanks will have to have another look see!
