coolant leak

[randyman]

2017 FLHTK about 16000 miles.  About once a year it will spit out about 1/2 once of anti freeze.  I am not sure from where but cannot find any leaks but inside of overflow tube is wet after it happens.  Anybody else seen this I'm thinking about replacing pressure cap.

Mine did that. It only did it when the bike was parked and cooling down. Just a spot of fluid on lower left fairing. 1st dealer pressure tested and said all good. 2nd dealer found a bad seam in top of radiator. Replaced radiator under warranty. Fixed. Hasn't done it since(2500mi)
