I have a 2016 naked. I have noticed that there are certain times that the exhaust note is deeper and more burly than other times, and it sounds like a beast. Like, especially 3.5-7k rpms open throttle it sounds freakin mean. Other times in similar riding conditions it just sounds more high pitched and less loud... More buzzy and electric almost.
i thought I noticed a trend of the better sound occuring shortly after warm up and when it is cold, however this isn't always the case. I actually got a booster plug as an experiment, wondering if the lower temps actually increased feuling which payed some role, but I haven't noticed much difference in this regard with the change.
2016 naked. Only engine mods are booster plug, k&n filter, removed intake baffle, optimized TPS, iridium plugs, and regular maintenance.
It doesn't really appear to affect performance. Mostly sound and feeling.
Had anyone else noticed this? And any ideas what may be going on?
