OMG! move this to the M8 Problems thread, maybe they all do that! sorry, couldn't resist...sure somebody from some other forum read this and reported Primary Knocking problems
When I finally got to see the bike, it turned out to be the driver side floorboard. Has a lock nut on it and some play. With the motor running it makes a nice harmonic knocking sound, that keeps perfect time...... crisis averted.
I follow these threads , having zero twin cam experience to draw on sometimes sorting out all the weird ****ing noises these M8's make sometimes drives me to distraction.
I had the same issue with my '15 RK and with my new '17 RK. It's the primary chain adjuster needing to go up a notch. Shift through 3 or 4 gears quickly keeping the RPM's at the max for your break-in miles. If that doesn't free the adjuster, slowly come to a stop in second gear and don't pull in the clutch till the engine lugs but before the engine stalls. The first method should do the trick.
On a brand new bike? I know the chain will stretch, but I wouldn't think that quick, IDK. I have almost 5K on mine, and the other day I stopped for about 10 minutes and when I started her back up, I heard a loud ticking/tapping noise, not sure where it was coming from, I was next to traffic and could not hear it well. My bike is completely quiet when cold.
Yeah, it was a goofy issue. I am going to relax, enjoy my ride and not worry anymore about my motor. I have 1000 miles, its going in for the first service. After I get it back, I'm going to ride the heck out of it. Tell you this much, I took a long ride on the 4th, i put 300 miles on it. whenever i stopped for a drink of water, I always had a nice conversation with someone who owns a Harley. They all loved my bike, so do I.
Ludington state park on July 4th. Great day, great ride. drank a lot of Bourbon when i got home and celebrated our nations birthday!

Have the same in my 17 limited. Only when starting up cold though. It sounds like those clacking ***** on a string from the 80's. not a methodical clack, but intermittent and not synchronous. it goes away when warmed up or is not noticeable.

That is exactly what I am hearing from my new 2018 M8 Lowrider. Much more noticeable when cold.
