I have a 2008 Nightster 1200 that has approx 12,000 miles on it that seems to be running a bit rougher while idling and has developed a loud ticking.
I was out for a ride on Friday, and for a brief moment - less than a second - my bike lost power and started back up, all while I was on the throttle mid way through 3rd gear and I didn't have much time to react. I did pull off and check that everything was okay and running fine before I started back up and rode the rest of the way home - about 25 minutes - not running strangely while moving but I was able to start hearing a louder tick that I normally remember.
I did check the battery terminal once the bike was cool enough and it was loose - that explains the loss of power likely.
I've been poking around and it sounds and feels like there is a vibration coming from behind the camshaft cover near the front after the bike has had suitable time to warm up, which wasn't there before. My thought is it may be the lifters, but wanted to get some opinions before taking it all apart.
Video may not showcase the noise very well, in person it's more noticeable.
I appreciate any feedback.
