cam chain tensioner
I have a loose cam chain , the chain was new some 400 race kilometers ago and I can see no reason for the chain to be so loose, can any one tell me how far the tensioner should extend from the main body, Also how many links there should be in the cam chain ( I cannot see any reference to this in the manual) . and last question . How can you remove the cam chain from the crank sprocket without splitting the crank cases( it is restricted by the guide cast into the lower crank case)

Whether it is good or bad,I took a blunt screwdriver and gave that cast piece a pop.It came off nice and clean and solved the problem of splitting the cases.I believe the manuqal gives a spec on 20 links of chain.

bahahahahahahahahahaha!! good one, pete!
I did the same kind of thing to Buddy's motor, although i didn't mean to.
IMO that guard is like an appendix or tonsils, remove it it its "inconvenient"

There is no way the chain should be loose. The OEM CCT has a ton of "adjustment".
pull the 2 slipper/guides as well as the chain. They are prob fukkered.

Thats interesting I can only get the tensioner to move 13mm ( I'm sure my old ZZR had around 40mm movement)

IMO 13mm is "a ton of adjustment" in that application.
Are your slipper guides in good shape?
are your cam drive gears in good shape??
The cam chain is only $60+/-, and the new one should tighten up nicely.
If you'd rather, I have an APE manual chain adjuster I will sell you but I REALLY don't recommend it.
(VH: your turn  )

Like you, I sure would want to "KNOW" what it was first. The easiest thing to do is to break the 10 mm Bolt lose first and remove the Cam Chain tensioner and see if ti is defective!. Lift the Paw and push it in and out! Use a small Screw Driver and turn it in and out! If it is fine then I would see just how deep the cam chain slider needs to be pushed in and measure that against the Auto Adjustor. If it is more than the Adjustor can handle then I would next take the cover and look at the Sliders!

I wonder if the adjuster didn't get hung up and that is why he's seeing alot of play.

some folks pull the CCT by taking off the two 8mm screws, without 1st removing the 12mm bolt/cap over the spring. That fully extends the adjuster.
Then if you then remount the CCT you will break the lil crosswise dowel in the pawl and have NO compression against the rear slipper.
(and a VERY loose chain)

Vincent,
I have a CCT amongst my "garage jewelry" with a broken pin, and i am sure you can guess how it got that way.

And JUST WHen I thought you had run out of things you either had done or spares of!! WHen I was doing a lot of testing on the ZRX and a few people were waiting for me to get finished changing the Needle Position (All saying take your time) I pinched a Diaphram for the first time in my life! I even knew the sound was not right but could not see it!! I had to buy a spare set of Carbs for $140 because I already knew from Drilling the Hole in the Lift Silde too be that Kawasaki wants close to $100 each for them and this was in the 80's

What Karl said. The stock tensioner is near perfect. Must be a broken tensioner or guide.
90% of those using "manual" tensioners over tighten them.

I think DM is being Kind on the 90%! The Only use of a tool on a Manual tensioner should be to hold the Hand adjusted Adjustor (Which should be done my rotating the engine clockwise) and to tighten the Lock Nut!
AND if DM Finished the statement it would be "Over tighten them which causes a rapid wear of the Guide which loosens the chain even faster"!

Thanks all for your advice, closer inspection revealed the broken dowel . I was getting a false reading of the CCT when I tried to install with it fully extended( expecting it not to be able to be installed) it would go in all the way , what I didn't realise it was releasing the ratchet while in the housing. When I removed the CCT it was fully extended and the ratchet seemed to hold it fully extended. I've ordered a new CCT
Cheers Chris

Karl, You are the Winner!! sc57 also smart to get a "STOCK" one. You remove the Bolt and release the spring and then lift the lock and push the arm back in! Then Bolt it in place!

Chris,
if you can cancel yr your order you can save yourself some bux.
Nothing magic about that lil dowel. Harry found an old drill bit which was the same diameter as the dowel and made a replacement dowel.

Thanks the dowel is simple but to add to the problem is the amount of slop when the ratchet is engaged. Its also interesting with this problem I noticed the CCT was installed upsidedown,( by previous owner) on first inspection I did not think it mattered but perhaps it has accelerated the wear on the ratchet. I'll have to wait and see.
