About 4 months ago, i installed a screaming eagle manual primary adjuster on my 2015 dyna wide glide.
I have had to re tighten my primary for the second time now, because it keep backing off from my setting.
This last time i checked it, it had an 1 3/4" slack at the top of the chain. I triple checked that everything is tight and the locking tabs are folded over to keep the adjustment locked in place. Nothing has come loose but this keeps happening.
21,000 miles on the bike.
Any suggestions would be appreciated.

 

Not sure why it would loosen up but was wondering if yours is noisy. Mine sure is

 

A little noisy on the downshifts coming to a stop.
Other than that, not so much.

 

Mine rattles like a can of bolts

 

Have you checked it to see if its come loose like mine? Because mines sounds like marbles are bouncing around inside the primary.

 

Have you rotated the chain and checked tension in different spots? I have no experience with these retrofit kits or with the automatic adjusters, but over time the chain can develop "tight" and "loose" spots. My FSM states that chain slack measurement must be checked at the tightest spot, as doing otherwise would result in a too-tight chain. I wonder if it's possible you've randomly done it right, but your follow-up measurement happened to be at a loose spot... I think it would be very rare (unless the chain is new) to get the same measurement at any point of rotation. It's a little bit of a pain to find the tightest and loosest spots, as it's difficult with the primary cover on (but not impossible).

Please note: All my knowledge on this topic comes from a 2000 bike. Sorry if it isn't applicable in the slightest!

 

I did rotate to find the tightest spot before adjusting.
But, some how its jumping from 5/8" to 7/8" adjustment. To all of a sudden..1 1/2" slack.
Just dont understand how thats happening.

 

Mine doesn’t loosen up but it does make a lot of noise. Pretty sure it is the chain running over whatever the tensioner is made of

 

Exactly

 

why a manual adjuster. seems folks are having problems. Pro and con of the maual vs auto tensioner
