Same here. 4 bikes two 18's and two 19's they all had it. Made me crazy but now living with it.

I think it is pipe bang, most of the time it appears when going steady and slowly or inadvertently close the throttle just a tiny bit. Bang! Sounds like a hard knock and comes from the cylinder outlet area.

I tried this for hours and it also appears when going downhill with closed throttle or just after the throttle has been closed. I first thought that pieces of branches or stones hit the bike on its plastic bash plate but it appeared always on the same spot of a 15 minute lap.

In the meantime I can live with it, but I can remember that I was really pissed off when I first heard it and was unable to find it though I spent hours and hours....
