Tucson, AZ | Sorry for not being up to speed on this, but I've only had my V for a little over a month and I'm still in the learning process. I have my stock pipes on now, but have installed the factory high flow air cleaner. Is remapping required for this mod?
TIA |

Pittsburgh, PA | if you increase air you Must increase fuel or you will risk damage to your engine. If ou purchase a stage 1 or stage 2 it will come with the air filter you just purchased.. |

Gainesville Fl Home of the Gators | If you just added a filter without any other mods you do NOT need to remap. Without also changing the exhaust; the injection can cope with the small percentage of change in flow |

Pittsburgh, PA | if you put a k&n air filter on a stock already lean mixture would you loose a little power since the bike is already lean from the factory and you increase more air. or can the close looped system adjust for the increase in air? i keep forgetting this is a close looped system |

Yes. Well, yes to a certain extent. With stock, unmodified exhaust you will be fine. |

the clossed loop is good for about a 5% variance, and the filter would not make a change anywhere near that. The bike will only draw as much air as it can use, and with a restricted exhaust you are not increacing demand by that much. Switching to a free flowing exhaust greatly changes the demand for air, and that is where you start running into mixture issues. Most often not mapping a bike with an open exhaust will give you a rich running bottom, and a lean top when looked at with a moniter. With a restricte filter[stock] that condition is somewhat redducedd at the top do to it limiting the available air for the mixture, and subsequentlly making it richer |
