So I decided I needed some new items and more power from my XR. I ordered the Freedom Performance Duals and a PCV. I did a baseline dyno run for power/tq and AF. 86hp, 103 TQ with the Stage 1 ECU, strip removed, Vic air filter and Chesapeake Cycles aftermarket slip on exhaust. They have them made by someone with a larger exhaust outlet ( 2 inch versus 1 1/2). The AF ratio was lean at idle, lean further between 2500 and 4000 and good above 4000 and between 1500 to 2500. Cruising RPM was not smooth at all so the addition of the aftermarket controller is much needed for better power and all around riding. The pipes will be here in about 2 weeks so stay tuned!
