Its just an OEM needle (ktm or yamaha - either should be able to look it up - ktm will be cheaper). The pilots and mains are OEM Keihin, same as any other bike.
I owned a 2010 for over 300hrs and only had it spitt a little coolant while free riding. 1st gear for extended periods with very little airflow. Not boiling over or cooking. The water jackets and volume of the Gasser radiators provide pretty decent cooling. Same can be said for my 2013 model. I also run quite lean jetting. I doubt you'll need a fan.
XXXX for the rads, Bundy for the rider!
