Re: Spark Plugs with Two-Step
Bobby this what I have been using NGK UR45. Mine are grey to white. On the 2 step same as you. You can run lean around the pits and return road cause you have very little load on the motor. With out fear of burning a piston. Somebody correct me if I am wrong still learning.
