I've accumulated more than 1,000 miles, about 40% of it at highway speeds (by necessity - I picked it up out of state and drove it home). I can guarantee you that it does not go away with miles, nor with more seat time. Nor does air pressure, gentle input, gritting your teeth, colorful exclaimations following suprise and terror, work.
I believe the problem is two fold; allignment (toe in) and electronic power steering, speed sensitive, calibration. One acting against the other. In a preliminary Knowledge Base released from BRP, it emphasis'd the importance of re-setting (with BUDS) the PS - after - allignment adjustments are completed. This tells me that BRP is on the right track. I wouldn't be suprised to learn that production PS units were different than pre-production units. That + faulty allignment may have conspired to create this debacle. Speculation on my part, we'll see.
Toe in adjustment is a very slight but precise adjustment on every front end I'm aware of. Usually it's less that a 1% adjustment from dead nuts parallel. However, my young service advisor told me that "eyeballing the front end, it dosen't look like it's out of adjustment." I only wish I had vision that equals his and Clark Kent's.
In the mean time, ride safe. Pay no attention to the semi's honking their horns in consternation as they blast past our weaving, inebriated riding style. My apologies for tone of this reply. Color me frustrated and feeling like a fool for spending so much money on a touring machine that won't tour.
