   we are doing some tune up of a 1990 gsxr250rr and we notice the previus owner put 2 different sparkplug
   3 plug was ngk cr8eh9 and one cr8e . the cr8eh9 have less treads than the cr8e but both plug are exactly the same size from electrode to o ring seat . What is the plug that you run with your gsxr250rr?
   
   Thank you
