Got an '04 VL800. 23,000 miles on it, runs great. Did a honest abe on exhaust, removed all the guts last year, runs great and love the sound. looking to go louder though. Im doing the spring tune up and ordered a K&N air filter. Currently have OEM filter on it. once i get and install the K&N air filter, will it still run fine, with no re-jetting needed. from what ive read on here from others, sometimes runs fine, sometimes runs like ****. not looking to mess things up on my baby. Also, looking to get either cruzers or straight shots in a few months..what will sound best..i LOVE LOUD deep rumbling pipes. also, how do i know what re-jetting kit to get. are they all the same sizes, or what. im pretty mechanically inclined and sure i can do it myself from what ive seen online, just never had any re-jetting experience. Thanks for the feedback!!!
