2011 Suzuki GSX-R750......the issue only "seems" to happen in gears 4-6, though there is no logic behind this. I rarely ride 400-series or QEW, so my usual top gear is 3rd, occasionally 4th. While cruising along in the upper gears recently, I've experienced a cyclical power loss at steady throttle opening....normal power->low power (can't maintain speed)->normal power. It's a rather dramatic loss of power....then the power kicks back in quite suddenly. Any thoughts?
