Most late model H-D touring bikes (at least 2007 and up) come with the H-D primary chain tensioner installed. In fact the port normally available for tension adjustment was eliminated on the primary chain cover on any bike that had the chain tensioner installed at the factory.

I used to Hayden M6 tensioners on a couple of bikes with no problems. However, I did wonder why there were two springs, one inside the other. Then I realized that either spring would retain the pieces of the other spring if it broke. Without this safegaurd, a broken spring could get loose in the primary with potentially bad results.

Novel idea, even if it does show your mechanical expertise is built upon supposition alone...

i put the automatic primary tensioner in my 02 fxdl a few years ago, and it was an easy install. it worked great for me. next bike was an 07 streetbob, and now my 08 sg. after having three bikes with the auto tensioner, i feel it's a great improvement. it's just one less thing to worry about.

If you've had the bikes only a few years each, how do you expect to have enough experience to be the judge of the effect parts have? Just sayin...
