Hi,

My R3 has about 9800kms on it now, bought in May 2015. I have noticed 3 times recently that while I'm riding, the tachometer and speedometer have been bouncing all over the place. They both drop to zero, then the tach flies all the way to red line, then back to zero, and then it seems to reset itself and find the current rpm's. Meanwhile the speedo is just bouncing through random numbers across the board. It's intermittent and only lasts a few seconds. Usually there's no actual change in the bike's performance other than a slight hiccup which is the reason I look down in the first place to see what's happening.

Thoughts??

Sounds like a faulty connection. Start with unplugging the harness to the back of the cluster, check for corrosion. Could also be corrosion on the speed sensor connector on the engine but I would think that would only affect the speed and not the tach.
