During my morning commute to work the other day the seas of traffic parted along a stretch of I-94 where there's no place for a police car to hide. I rolled on the throttle a bit and was enjoying the smooth and steady manners of the R at higher speeds. About the time the speedo indicated 120 the handlebars started a casual back-and-forth dance. For a fleeting instant I was convinced that a tank slapper was in my immediate future but the oscillation didn't grow in magnitude or increase in frequency. I eased off on the throttle and the oscillation was gone by the time I was back to about 105.

This was the first time the R felt unstable; it was a bit spooky.

I run the large removable windshield and I'm wondering if it the airflow over the shield at those speeds may lead to the wobble I experienced. Another thought is to check the neck bearings again to make sure they're properly tightened. The bike is a mere 1000 miles past a 5000-mile service so I would think the neck bearing adjustment should be OK but I'll have to check.

Has anybody else experienced something similar?

IMHO I don't trust large windshiels above 90 mph and they do get a little unstable around traffic and large trucks especially. The mid shields are good for higher speeds.

I had the same issue on my Dad's A model when I put the Pingle extentions on it. It made the windshield stand straighter up to deflect the wind over your head, but caused a nasty wobble above 110. Now when I ride it I take the shield off :angeldev:

I hit 110 on a pass last week at the drags. I got a real strong pull to the left as I let off the throttle. Mechanical check said everything OK. I'm wondering if this was caused by the windshield ? It would seem to jive with others experiences.

You could try taking off the mentioned removable windscreen, run it back up to speed and see if it repeats. If doesn't recur can do the :dance: that at least it's not the steering stem etc.

What is your tire inflation? I run around 42psi to avoid weaves at high speeds, the few times I have to enjoy such hooning. Windshields can cerainly create such a weave. Try it without the shield, and also try higher tire inflation pressures.
