Cam chain life

[PieEater]

As you've got a manual tensioner, you might get premature wear if you don't get the tension right.Mine still has the original tensioner, but she's only done 35,000 miles.

As someone with a manual tensioner it's pretty easy to tell by ear if you have it set with too much pressure on the chain. Conversely it's next to impossible to know if your automatic tensioner is going to give out and destroy your engine. Pretty much equal chance of either happening IMHO, to quote - ride more worry less.
