Default Motor Making Bad noises

Took a nice ride down to Ocean City, MD yesterday with my buddy who rides a Harley Road Glide. Headed back, we maintained a pretty good pace with him leading the way. Then I hear a strange "metallic rapping/tapping" sound. Seemed less when I'm under load. When I let off the throttle, it's accompanied by a raspy rattling sound. Pulled over to do an inspection. Tapping seems to be coming from lower rear cylinder, rasping rattling (when I let off of the throttle) seems to be coming from top of rear cylinder head. No smoking and seems to be no degradation of power, although I didn't really get on it after I heard the noise. I limped in home last night and put it in the garage. To make matters worse.. I have to hear all my Harley Buddies talk about how they I broke down trying to keep up with the Harleys! SMH. I'll try to do a sound clip later today.

Default Vido Clip of tapping of motor

Did a quick video to try to get the sound of the tapping of the motor. Kind of hard to get the true sound.

Turned out to be a private video. You are asking for help with a bike we know little about cuz you won't post a signature with a description of it and the mods you've done. Help us to help you, will ya huh?

And the year is.....? If its a 2014, we may know what the problem is. You tell us and we'll tell you, since you are playing hide and seek with the ID of your bike. Yes, I can be a cranky old fart. Rank has its privileges, being the most senior guy here.

Simply make the video public. Then we will be able to view it.

How many miles on the motor? Any motor work done like a 116 kit or cams?

There has been some talk lately about not letting the motor warm up before heading out and opening the throttle.

Could be piston slap. A pain to fix but not the end of the world. Could also be cam chain tensioner is slack as mentioned or even a referred noise coming from the primary from the compensator.

Could be a drained tappet or tappets. How many miles on the oil and what brand/weight?
