Just got finished installing Oxford heated grips. First time I've removed the plastic. I finished up with two black screws left over (don't you just hate that!). They are about half an inch long, phillips head, very similar (but a bit shorter) than the ones that go into the vent corners of bottom trim (the part that bridges between the left and right cowling above the front wheel. They are threaded like wood screws (not bolts) obviously meant to screw into plastic. I have no idea where they go.
