My 2004 XB completely stock except for the Lattus replica exhaust I built, and some mapping changes put 89 horse power to the ground with the tire smoking from slipping on the dyno drum. It ran good for what it was. Basically a high compression 1200 with decent heads and N7 cams. The bad thing was the rev limiter cut in before the motor ran out of steam, otherwise it would have just outright shit the bed. Loved the torque. The thing was a missile exiting a corner, frequently with the front tire hanging. If I had kept it, I would have put a Sportster/XB9 primary on it to get more wheelie fun at the expense of dropping top speed back from 136 to about 125.
