I have an 18 with stage 3 installed. It spark knocks horrible. Have had it retuned with a Power Vision and it still spark knocks even in 50 degree weather. The bike runs extremely hot. No cat in the header and tuned with a Power Vision. They say nothing wrong with it. I wonder if mine is sumping causing it to run extremely hot in turn causing the spark knock. They have no idea or even will acknowledge the spark knock problem. They did retune it with the Power Vision for free so uh they obviously think there is a problem.
