After riding a couple times since I began this threat, I can absolutely say the problem occurs exclusively with downshifting. So, yeah... Seems fairly clear the issue is with the shift lever positioning. Many thanks to all for helping figure this out.

That really does feel like what's going on, as it happens more often when I'm wearing thick combat boots, as opposed to when I'm wearing my Doc Martens... I'll adjust it next week. Thanks for the advice.

SITUATION: I've got about 2500 miles on my FJ09. I live in Colorado and ride exclusively on paved roads. I ride conservatively compared to most dudes I know, and rarely carry a passenger. No modifications to the bike. ISSUE: Recently, between 2nd and 5th gears, the gear position indicator goes blank after I shift, either up or down. It usually corrects itself if I release the throttle, shift back into the previous gear, and repeat. No other issues with the transmission, but this has been happening more frequently over the past ~500 miles. Otherwise, the clutch and gearing is actually one of my favorite aspects of the bike - very fluid, precise, and predictable. Diagnosis? Recommendation? Thanks in advance.

I understand in a very vague sense that every object has a "natural vibration" frequency; not much past that. It's a somewhat arcane subject, but I was wondering if anyone on here had enough of a physics/engineering background to explain the concept and how it actually affects motorcycles. What factors determine the natural vibration of a bike? How does it affect/limit how bikes are designed? How does it affect how we ride? I've found that the experience of riding is enhanced the more I really, no-joke understand about the physical forces affecting how I ride. Increased confidence is part of it, but it's more so an enhanced appreciation, the way you might get so much more out of a guitar solo if you really understand music and acoustics.

Word... I've noticed some speed/RPM-related vibrations here and there, but I'm coming off a H-D Sportster. It'd be difficult to deliberately engineer a modern motorcycle that vibrated as much, in as many different ways. It's entirely possible my FJ-09 could be vibrating entirely too much, and I'd have no idea.
