Default Twin-Cam Cam Chain System problems

Hi Folks,
No too sure which area to put this, has anyone had problems their cam chain system and the plastic shoes used on the tensioner? I am asking after reading this article on J&P blog (see link below) that affects all twin-cam engines anywhere between 15k and 70k miles. J&P are recommending going to a gear system but are there other options.

I believe this is only an issue for 2006 and older TC models. The newer models use a hydraulic tensioner as opposed to the spring tensioner of earlier models. Some have had problems and many others haven't, but if in doubt, it is relatively easy to pop off the cam chest cover and inspect for wear.

I wouldn't take it as gospel anyway...on my 02,I heard a slight hissing from the cam cover one day,so I replaced the tensioners at 75,000 miles.It was the middle of the summer and my only bike,so I just threw in a set of stock tensioners and kept riding.that was almost 25,000 miles ago,no problems so far.

when I replaced mine,the inner was just barely down to the metal.

and these are the "bad" design? I've always ran Amsoil synthetic,donno if that made any difference or keeping it changed.

Yeah they fail, consider it a wear item on the earlier TC's. Check every 20K, replace as necessary. They're just trying to sell you new cams. If you are looking a cams anyway, go for it, if not, don't let it scare you...

Plain and simple scare tactics trying to generate sales.
The old system was not good, but a check every 20-30,000 miles was all that was needed to keep things in check.
I've not heard of an any issues on 2006-up bikes.

I got an e-mail from J&P that had that article in it, they made it sound like a newsflash or something.

I don't know what year bike you have, but as stated in the TC88 they are known to wear, the TC96 has hydraulics so they will last a lot longer. I went to gear drive, but only after having my crank trued and welded. If you go to gear drive you better check your run out, or you will have problems, also Zippers has a kit for the cam tensioners that you may want to look at.

Replaced them on my 2000 RK @ 56k. One was almost to the metal and the other was about half way.

JP is trying to hawk the S&S kit, period. Many people riding the 06-earlier bikes have used the HD kit, and there are tons of people riding the 07-up bikes that came with it stock, and I'm not aware that people are having problems with the newer design.

Changed cams in an 08 and the shoes had at best minimal wear @ 51k
