MISCELLANEOUS INFORMATION ABOUT YOUR BIKE’S JETTING SETUP:
I had Evan Steel Performance (ESP) in Tucson do all this work and provide the materials. Carb tuning is an art that I have found that I do not possess.
They tuned the bike using their dynomometer and the horsepower increased from 24.5 at about 10,500 to 29.2 at 12,500. These figures were reflected in the bikes improved performance on the street and a vast improvement in the low end drivability. I chose not to go to pod filters and so sacrificed some top end power for low end improvement. The stock 24.5hp is probably true, this machine was noticeably weaker than my 2007. The 29.2hp is in line with Yoshimura's predictions. The only downside is that the pipe is awfully loud. I would like to attach the dyno charts if I could work out how.
