On my 2020 Ninja 1000sx, I'm having some serious problems when shifting from first to second gear. The bike shifts into Neutral from first therefore reving the engine up significantly. First couple of times I thought I was doing something wrong, but I wasn't. I've been riding for more than 40 years and never had this problem. The bike also shuts off, when taking of from a standstill ,uphill, even with a slow release of the clutch and with extra throttle. I need to contact Kawasaki or my dealer for a response to these issues.
