Handlebar control symmetry

[Uncle Sixer]

If the rubber on the throttle tube contacts the housing like on the clutch side the throttle will hang up and not return.

Well, I wouldn't try jamming it up "interference-tight"... but I just never saw that much gap there on any other bike.  And give-or-take a little wiggle room, that gap matches the 1/4 inch the controls are offset compared to other side...

But, for the sake of practicality for the remainder of summer, I think I may be able to live with it if I can get a wrap of electrical tape in the gap or maybe just go over the white plastic with some black sharpie.
