Important Harley twin cam info
I was over at the J&P Cycles web site, checking on a sprocket and saw an important article regarding the twin cam bikes.
Primarily, about the cam chain tensioners failing way to soon and trashing the engine. Mostly, not covered under warranty, according to the owners comments!

I don't own a Harley, it was posted on the site today. Apparently it's still a problem, dude.

I'm not 100% sure but I think it mainly a problem for Twin-Cam motors prior to 08,

Just so you can be all caught up, there is also a whole lot of inner cam bearings that go bad. This usually destroys the engine. (not re-buildable). Loose rollers inside the case is a bad thing, for sure.
A gear drive cam set up eliminates the chain tensioner thing but it must be difficult to fit up correctly because a lot of those have a loud whine which may be from the fit of the gears, I'm not sure. There is a much better bearing available for the inner end of the cams too. A good practice is to pop off the timing cover and have a real close look at around 25000 miles.

Crank run out is the problem with gear drive. Word is 09 up hyd tensioners are the way to go.

If you warmed the bike up, never got on it hard until completely warmed up and did not lug the engine (the engineers want you to cruise at 2900 to 3100 rpm's) then the old tensioners would last 80k plus miles. The ones that ran into problems were the throttle blippers and those that thought they should be cruising down the highway at 2200 RPM's. They were having issues at around 25k miles.
