idle dips

[jeg112]

Hi,
My 2015 Citycom usually idles within the normal range of 1,550-1,750 RPM, but I've noticed that sometimes it will dip to somewhere around 1,400 more or less.  It seems pretty random.  Like at stoplights sometimes it idles low and then something will kick in and it will go back to normal range.  I'm not sure how long it has been happening, but it seems to be happening more often now (or I'm just noticing it more).  Just wondering if anyone else has had similar experience and if there is anything on my bike that I can take a look at.  Anyone else suffering from occasional-low-idle syndrome? 

Thanks fellows!

Mine has done this too and it was while I was messing around with tuning so I think fuelling or air/exhaust leaks are the most likely causes. In your case, the first thing I'd check is the air filter since they clog up pretty fast and that affects fuelling.
