Cam Chain Tensioner

G'day everyone
I've been wondering how long the rfs mechanical/auto cam chain adjusters last. My bike has hit about 50 hours and as a bit of preventative maintenance I'm considering a manual adjuster by DJH. If anyone has any info, opinions, comments or experiences please let me know.

I have never fitted an aftermarket one, The new genuine ones are not that expensive, so I just fit new ones of them. It's more the spring inside them that slowly looses it's tension, But usually when I put a new chain in I wack a new tensioner in as well.

How long would you get out of a cam chain?

I personally change them every 100 hours unless there noisy I might do them sooner. They are so expensive. You might get 150 hours out of one, the ktm chains are pretty strong.

The stator is holding up great, no complaints at all. It's as easy as swapping the old unit out for the new one. A little bit of wire rearranging will be required for the DC conversion. The whole process is super easy and the instructions are perfect too.

Cool, I must have got the dc conversion one as they sent me another reg with the stator. Stator bolted straight in, only had to cut a zip tie off, but I haven't looked at the wiring for the reg yet, Should be simple enough hopefully. If the instructions are good I should be right. I will just buzz you if I stuff it up

Back to work tomorrow for me and it's past my bed time. Talk to you tomorrow

I would have thought you would ditch te stock and custom make a manual one using the old housing?
Did you think about that JJ?
I would like to see that done.
