Got another 7.5 tanks through the GXII at our race meeting today, and it's really starting to come to life now at just over 1/2 a gallon (got it's first real leaning out today)
Just love the way this motor lays down the power, with it's stonky but smooth bottom end response. It is really easy to drive, and just devours jumps with a light tap on the trigger.
I know it's taking a while, but please be patient. This motor is worthwhile waiting for, trust me
