I have a 2015 thruxton 900. For some reason when I turn it on the RPMs shoot to 6K RPMs and stays there for about a minute or so then drops down to where it barley stays on then it'll die. I've tried to adjust the idle knob on the side but it makes no difference. I'm not sure what to do to fix the issue. It did have a fuel pump issue not to long ago but I replaced the little filter and fuel pump that's inside the gas tank. But as I said it starts but has a rough idle now then it'll cut off.
