Hey so i have been having a lingering issue with my 2013 rmz250.

upon start up, it runs rough to where i cant touch the throttle without it dying. after it settles it runs ok but is a little poppy.

I had the grey(rich) coupler installed and changed to the white(lean) with no difference noticed. I also had a power commander fuel mapping that i pulled that made no change.

Also I have the hot start cable unmounted from the bars and coiled up along the frame but the cable is loose, not being pulled on.

Could this be a sensor or injector?
