After my bike sits all night and I start it for the first time everyday, It has a knock in the lower engine area. It doesn't do it the rest of the day no matter how many times I start and stop. The knock last a few seconds and goes away. Any Idea's. 2000 Ultra Classic

Thanks, Tim

 

Sounds like a potential compensator knock. Lots of possibilities, but that's my first thought...

 

Compensator or the nut may be loose like mine was!!

 

See if you can tell which side it's coming from, which side it seems to be louder at, & is it a low knock or a loud tick? Sounds like it could just be a lifter bleeding down, louder on the right side & more of a loud tick?

 

Gotta be the lifter. No worries. Unless it doesn't get quite in a few seconds.

 

Tell us what a lifter bleed down is and what it sounds like DTTJ it will help the OP isolate the sound...I hear it a lot but no one ever explains it.

 

Thanks for the info guys, I'm pretty sure the noise is on the left side.

 

The lifter is hydraulic & the oil can "bleed" out of it over time, that will allow there to be a little clearance between the lifter & pushrod or the pushrod & the rocker arm. It just sounds like a loud tick & usually goes away in a few seconds, it's more likely to occur near the oil change interval as the oil loses some of it's viscosity.
