Are you sure that it is just the throttle grip cover that is rotating past stop? On a 2000 with heated grips the throttle grip assembly includes the grip cover over a throttle grip tube (which slides around the handlebar), with a wheel at the forward end where the throttle cable ends are held, and an electric wire that runs thru the hollow handlebar into the hollow throttle grip tube and connects to the grip warmer. I am not sure if the grip cover is glued to the throttle grip tube or not. This assembly is held in place by cutouts and a tab on the throttle cable holder; these are aligned and the throttle grip tube is pushed forward on the handle bar, then rotated backward so the tab holds it in place. The forward end with the wheel is covered by the throttle cable guide and cover.
If the problem is that your grip cover is slipping on the grip tube, check with your dealer about how the two are attached (friction fit? glue?). According to the parts diagrams, there is no separate listing for the cover; looks like you have to buy the assembly, and there are about 90 choices depending on whether the grip is heated or not, grip material, chrome accoutrements, etc. I'd try to peel the front end of the grip back aways, put some silicon adhesive on the underside, and then roll it forward and see if that held it; but then, I'm cheap.
If it is not the grip cover, but the entire tube/grip assembly that is rotating forward too far, I suggest that you need to fix it ASAP. If the cutouts rotate to the point of aligning with the tab, the grip/tube could shift rearward along the axis of the handlebar, which would put your cables out of alignment and put stress on the throttle cable guide and cover. Good luck.
