If you read pats cartest web page re the Ivan’s jet kit, it addresses a number of issues with the stock jetting,ie, lean running mid rpms and overly rich running at high rpms along with other issues.
If your Dyno man says it’s running slightly rich as opposed to overly rich then that’s a bonus.
I had my fazer thou pre Ivan’s and had mike install the kit, needles to say it was a big improvement over stock so if I had mine dynoed I wouldn’t be bothered if it were still slightly rich.
I must admit though that I would’ve expected more than 134 bhp and 78 ft lbs of torque, sounds like stock figures.
