Hey guys! I have noticed recently when I start my 2020 ninja 400 the RPMs go much higher than it used to and then after about 3 seconds will go back down to its idle RPMs. It also sometimes takes a little long than usual to turn over (maybe only like 3-5 seconds longer than usual). Any ideas what this could be? No lights in the dash and has ran perfectly since I bought it a while back with only 8800 miles on it right now.

For reference, it didn’t used to do this and my friend has the same bike and it does not do this.
