My primary chain was a little too tight, so tonight I took out the automatic tensioner and reset it. Took it for a short but hard 5-minute ride. It now clacks a little. I'm assuming it's because it hasn't fully adjusted yet and it's a little loose. My question is, how long does it usually take for the automatic tensioner to fully adjust???

 

Someone passed on some advice to me, and it seem to work for me, is to run your scooter up to about 40 MPH, let off the throttle and without pulling in the clutch hit the rear brakes fairly hard. This I believe will give you maxium slack on the bottom of the primary chain, causing the tensioner to adjust for the slack. Your not out anything. Hope this helps.

Just curious; how did you know the primary was too tight?

 

I would also be interested in what led you to investigate the primary chain. If it is auto-adjust, why would you need to reset it? If it made the chain tight once already, why would reseting it prevent it from tightening again?

Is this something that other '09 owners should be watching out for?

 

I've been chasing down a noise in my primary for a while. One guy suggested that the chain tensioner may not be putting enough tension on the chain, so I manually forced the tensioner to move up a click. After I did that, I got a whirling sound from the chain, which is a classic sign that it's too tight.

So, no I don't think this is something that needs to be worried about, as it was from my own doing.

 

Harleys make noise. Don't go looking for problems that don't exist.

 

why didnt you just take it to the the dealer? just curious i would rather let them screw it up and have to fix than me..

 

If it ain't broke don't fix it. If you think your RK makes a little noise now buy a fairing, you will think someone traded your nice quiet RK out for a 1930's John Deere.
Don't micro manage a Harley it doesn't pay!!!

 

Might be a good way to twist a crank on a newer bike. Not sure I'd do this.

 

I preadjusted mine when I installed it and never had a problem
