I've had my XB12 for about 3 months now and really happy so far. The previous owner had Vallejo HD dyno-tune it with a Directlink, it has a special ops pipe and Buell race ECM and open air box/breather kit. My question is can this setup be tuned for more lowend torque v. max HP? My previous Buell was an X-1 with complete Buell race kit and it had monster torque...if you sneezed while pulling away from a stop in first gear, you'd be on your bike in the blink of an Eye. The XB12 is not nearly as brutish and doesn't power wheelie like my X-1 did. Are the XB12s geared significantly different than the X-1s? Whats up.. I love the XB12 but miss the monster grunt of my X1...

Your 12 should have plenty of torque. Do a couple of things right off the bat: replace plugs (wires too if they appear worn or brittle in any way), make sure your air filter is clean, change your oil and do a TPS reset. This takes care of 95% of any rough-running issues our XBs have, and doesn't cost much.

Once it's running up to spec, one thing you could do is swap out primary gears for the XB9 gears- they are something like 11% steeper ratio than the 12s are.

Gunter.

That is the torque curve I am looking for!!!!!!!!

Any thoughts on why it is so?

Exhaust, Ignition?
