I did a slight modification of your procedure. I have handguards and foam grip covers on my wee . I took a small nylon cable tie and placed it between the grip and the extra weight/spacer (came with the handguards) and tightened the cable tie somewhat. I cut the tail and recovered the gap/cable tie with the foam. Works great and the throttle returns without impediment. Thanks swingblade.I had the same issue, it didn't hurt anything, just annoyed me. What I did was to take a black plastic tye wrap, place it between the grip and the switch assembly. I tightened it just enough to take out the slop but not enough to inhibit the throttle from snapping back to idle. Cut of the "tail" when you get the right setting. Not noticeable at all & works like a charm.
Another ex Beemer who has gone to the wee. I sold my heavy, powerful K1200RS and bought a KLR. Found that the engine was inadequate and now have a brand new wee; absolutely love it. Still going to BMW rallies and seeing more and more stroms. At least we will not have to deal with a possible rear end problem.I have a 10 day old 2011 Wee. Same thing, slop in the throttle but not so bad that I can't deal with it. So nice to have good movement after dealing with a K1200 LT that had very poor throttle action.
