removing controls
Hal, there are two screws on each set of controls (one on top, one on bottom). I have to run to work, or I would take pics for you (I've done this so many times now ... not funny). you do not have to disassemble anything else to get the controls off (e.g. you do not have to take off the compression release, etc.). it's just two screws for each controller. they are easy to find.
things to remember: the controls fit over holes in the bottom of the handlebars so if you swap out bars, you will have to drill holes in the new set where the controls fit.
hope this helps.
you will have to reset the throttle, likely, after you take off the control. it is pretty intuitive, all of this is.
