I doubt weighting the GW's bar ends would help a steering wobble at all.
That would be too easy a fix. Even if it could at the least reduce the wobble it's the wrong mentality to consider repairing or covering any handling issues. Fix the source of a problem!
I agree 100%. And, I said address, not repair. I've read the boards, heard others talk, spoken to the dealer, spoken to Traxxion, and everyone except Honda and their dealers acknowledge a problem. Lots of fixes, but no true repair, and the "official stance" I've received from the dealer is "What are you doing taking your hands off the grips anyway?"
