The noise at idle and low throttle does sound like the compensator.
Some early 2014 models still had the "Harley" type so it could depend on when yours was actually built.
If you look under the bellhousing there should be an approx. 2-3" hole which if you stick a cheap phone boroscope camera through and point it towards the front of the car would allow you to see the rubber rollers if it is a Centa.
