Cam Chain Tensioner - any "preventive" methods?

[grinner]

I was reliably told today that cct failure is often caused by carbs out of sinc, putting different stresses on the parts.
Solution; balance carbs every 6 months or so.

brings me back to my original thought - de-sync affecting system heavily because of separate, not syncronized in head by connection cam chains...
Example - with same exactly CCT Honda have less troublesome DOHC inline 4 and no-problem SOHC

when they break...is it always the spring that goes?or something else?
cheers mates!!

From what I gather, it's always the spring that goes, thus the tensioner against the chain becomes slack enabling the chain to A) jump a tooth on the cam gear B) jam C) break (delete as applicable) almost certainly resulting in bent/damaged valves and other parts.

I have a 99 storm a simple mod to prevent the cct letting go
is to replace the m6 bolt in the back of the cct with a longer bolt
(25-30mm) also a washer and lock nut. The nut should be
screwed all the way down the bolt and then the washer put
onto the bolt. screw the new bolt into the cct finger tight then back
it of 1quater turn smear a very small amount of silcon sealant on
the bolt tread and washer then tighten the lock nut up to the cct.

This mod saved my zxr 750 at 160 mph @ 12000 rpm when the cct failed
there was slight ratteling but no damage as the cct could only let go
as far as the bolt would let it not enough to jump a tooth.

this mod retains automatic adjustment the bolt neens adjusting periodicaly

mate..nice idea but the vtr tentioners are different to kawasakis...the part of the cct where your bolt goes doesnt move in and out..it just turns...the actual rod of the cct moves in and out on a left hand thread.if you have an old cct take it apart and see what goes on ok?cheers mate..but if the spring goes on your mod the rod will just coil back into the slotted bit..confusing ....yes...also goodbye engine too..

kawasaki ccts move on a screw threaded helix...so the mod you talk about will work with them of course...vtr ones dont.
