I got a question on installing new grips. One of the guys at the parts counter told me they just slipon. I got the X2 grips that go with my streamliner floorboards. I have installed grips on my dirtbike before and I used a glue material. The instructions for the X2 grips say on the left just slip under switch housing and that will hold. The right side says refer to the manual. I don't have a manual right now.
