Hey, I've had my R1 rolling roaded just recently, and was pretty disappointed with the result, 130.1 BHP at the flywheel. 107 BHP at the wheels. The fueling ratio is sitting about 10.5/11:1 at 11000 RPM. I've been told it should be running 13:1, just wanted to check and see before i go back and say, it was sitting at 123.6 before, and i put it in to get chipped, which it is now running 130.7, and fueling is almost the same ratio. So a climb of just under 7 BHP. Just wanting to check to see if getting the fuel changed to the 13:1 will make the difference or if this is normal for any other R1 Mini's.

Any help/advice greatly appreciated!!

performance engines should be running close to 13:1 or between 0.85 to 0.95 lambda.

Cool, its booked back in to go on the rollers on Wed, its over fuelling is strapping the power and the fuel not getting burned is spitting out little flames from the exhaust. As much fun as that is, not exactly practical or good for anything really.
