I had work done by him. Was a very impressive motor. I know that he had problems with some people but he ported my ride. And he did a awesome job. Helped me jet it and it ran like a bat out off hell. And to be completely honest. On out trip to NYC to Glamis. My bike was the only one that made the whole trip. All the other banshees from builders that I won't name chased their tails and blew up the bikes 3 days into a 10 day trip. My gem performed like a top. Hell one of the guys was so pissed he went to the dealership in town and bought a brand new YFZ 450 off the floor. HJR never let me down. And I doubt he ever will
