Modern bikes are jetted as lean as possible for emission regulations. Freeing up the exhaust flow will accentuate that. Yes, you will need to jet to compensate. It is recommended that you have it done by someone experienced at the task who will return the bike in proper running order.I have an 06 Honda Shadow Spirit 750 and was thinking about putting on V&H straight shots or cruzers.
Two questions: Do i need a fuelpack when i put on new exhaust and if so, what is recomended?
