07 650L, approximately 500 miles. Have heard lots of info on the "uncorking" process such as carb mods, airbox mods and exhaust mods. Are there any drawbacks to performing these modifications? Also, is it necessary to do all the mods at the same time? I feel pretty confident in doing the mods myself with the exception of the carb modifications. Anyone know of a source to have it done for you? Thanks in advance!
