I noticed that a lot of people are installing Termi's on pretty new bikes, before the break in period was done. I have an 2009 1100 with just two hundred miles on it. I would really like to install the Termi's both for looks and to smooth out the roughness of the bike due to it running quite lean from the factory. When I called up a place to have the exhaust (slip-on, air filter, and ecu) installed, they mentioned that they do dyno runs before and after. I also read on the forum that it is advised to do a dyno run after installation for some sort of calibration. I am not sure why, I would have thought that the ECU that comes with the kit would not need to be calibrated. Running the bike on a dyno doesn't seem to be such a great idea before the break in period is over, 2000km. Are the dyno runs really recommended and are there any drawback to installing the new exhaust on a bike before it is broken in?
