It's not a bad idea to properly tune the carburetor when making any changes to the airflow through the engine. I emphasize properly. It is a science but if you are armed with good information and tools and an open mind, you can accomplish anything that you need to. Motorcycles are lean from the factory because of the EPA 'mandates' (an evil word these days) so even tuning a stock set-up can improve rideability. Some people think that because these bikes are liquid cooled that it's not harmful to be on the lean side, but that is just not the case. Lean causes heat in areas of the combustion chamber that liquid cooling cannot help out but adding fuel will help and, more importantly IMHO, affect longevity of the engine in a positive way. More power is a great side effect of proper tuning as well. Who doesn't want more power for just a few $$ more without changing any expensive parts in the engine? These bikes have a lot of bang for the bucks we shelled out and that is just awesome. I have fuel injection on my 1800 so it's a tad different for my tuning but the result is the same on how it helps the engine. Look around on this forum and you will find a plethora of info to help you in deciding on changes that you want to make. Good luck and post your results so we all can learn from it.
