Tuning the motorcycle

I recently purchased an exhaust system for my Yamaha R1.

I found a smoking deal on a Micron full system. This includes the headers, mid pipes and silencers. I always liked Micron. I purchased one for my old 2001 Yamaha R1.

Turns out, Micron has decided to pull out of the motorcycle exhaust market to focus solely on cars.

I purchased a use PowerCommander from a local racer. He had a map on the PCIII, so I was using it. The graph shows the original map (a downloadable map for a Two Brothers slip on) compared to my custom map. I am not overly happy with the Air/Fuel ration, as it really should be a flat line. The horsepower is respectable, but not terrific.

However, he had tuned another 2008 Yamaha R1 with a much more expensive Akropovic exhaust system. Here’s the dyno chart. Mine pulled more horses.
