Fred C. Dobbs Posted March 21, 2008 Share Posted March 21, 2008 I am considering replacing the stock exaust cannisters on my Billabio, with less restrictive aftermarket cans. Will I need a Power Commander (or similar device) to allow the fuel/air mixture to be changed to compensate for the exaust modifications? Thanks.

JoeV11 Posted March 21, 2008 Share Posted March 21, 2008 you probably won't need one, but if you search, you'll find many recommendations to get one even if just to fix the poor factory fi mapping. I have a stucci crossover and aftermarket mufflers and don't have one. but the plugs are still OK looking. Joe Link to comment Share on other sites More sharing options...
GuzziMoto Posted March 21, 2008 Share Posted March 21, 2008 The bike should run fine without one. If it does not, it likely has other issues that need correcting. But a V11 with or without aftermarket mufflers will run better with a fuel curve that has been optimized. A Power Commander is the most common way to achieve that. Keep in mind that it only works as well as it is setup, ie. the program. Link to comment Share on other sites More sharing options...
Greg Field Posted March 21, 2008 Share Posted March 21, 2008 Usually the later bikes like your Coppa run fin if the cans're all you change. Where in WA are you? (I'm in Seattle and work at Moto Intl.) Link to comment Share on other sites More sharing options...
