I'm not sure the method your bike (or any bike for that matter) measures and adjusts for variations in intake flow. Without thinking, my comments were based more towards a car with a much larger engine and much larger air flow. If the percentage of air flow difference is large, it could go beyond the scope of what the bike ECU can handle without some kind of tuning effort. | |

A custom air filter will not allow that much more air to go through the system to cause issues, even on larger engines. Usually you wouldn't need to worry about remapping (unless you wanted to), until you start on the major mods (headers, heads, cam(s), etc). Stuff that really makes a difference. | |
