taysidedragon, yep the cam is moving angle as well, its fixed to the sprocket but like you said the headcover is supposed to be in place and engine warm...
I think I'm going to buy that special bolt that pushes on the tensioner rod and adjust by ear. I had the chain noise on all the rpm range after I tried to adjust in normal condition.

I did your method as well Bryanj, without better result in my case. But I agree when you push the kick you give tension on the front side, the rear slacken and tensioner push further in, that make sense, but not on my bike.
When I removed the 2 bolts [19] it lift [5] up around 2 mm like said Billywingnut, I understand we need a bit of play especially when cold but I have no tension at all in my chain. The cam sprocket have angle play, giving to my opinion the erratic idle, knocking noise and random stall until engine shuts down.
The way i did tension by hand gives just a little slack in the chain and doesn't allow the cam sprocket to move around, I will give start today and see if everything sounds better.

Hi every one!
I finally replaced that camchain today.
The new chain is 63.7mm long when splitted, so was the one I removed...I feel like I spent time and money for nothing. It has been changed not long ago and that probably matches to head gasket change claimed by PO. Better be safe than sorry: the bike has a new camchain again... can't be bad -_-
Anyway, while playing around again with camchain tensionner, something poped up to my mind: I did a ride not long ago, after last time I opened the engine and post here, and deciced to "true" the tension to reduce camchain noise while engine hot, following normal procedure: noise became worst. Today, I noticed that the tension provided by the tensioner blade is stronger that the springs behind the pushrod.
When I screw the tensioner blade upper part [5] all the way down and untight the push rod bolt in front of engine [12]: the chain become loose.
I have to loosen the two screws [19] back around 6mm on the upper part [5] then lock the push rod bolt [12], then tighten the upper part to get proper tension on the chain.
I'm quiet lost here, the horse shoe isn't seized...did my tensioner blade become harder with age? Like it fossilized? Springs are too old with only 25000kms?
Anyone can help me?

Hi AndyD,
I took mine from CMSNL, they are good so far, David Silver got them as well, but they both sell complete gasket set, not the top one alone.

Like you said that engine eats too many chains, or the mileage is lying...even if pushing hard the revs, how come to screw 2 kits in only 25000km? Just to be sure that it's a soft link, there is no darker link on the original chain, is it? Anyway I ordered a new chain with soft link, if still noisy then I'll have to put the engine on the table.

Well, I replaced the missing damper! The bottom one was in place so did't need to do surgery. I tried again to play with the horse shoe and it's still moving ok. The two blades are in good condition.
Unfortunetely, the chain is still noisy whatever the methode I try to tight it (set up at 1200rpm, set up while pushing on the kick, set up at few degrees after N*1 TDC...) I noticed a soft link on the camchain... best thing to do now is to replace that chain, I guess.
I hope I'm not to confident with the tensioner...

Mine is a she as in french "moto" is a female noun you cant say "le moto", only "la moto". Hairygit I have another "she" at home that is often hanging up the rpm , i might not be rich enough Would the glue be, Bâtons comme de la merde?
French language even makes that sound good over here
Colle comme la merde  it's a bit meaningless

I think I would stick the damper to the lower end of the blade after removing any traces of oil, with something like ‘sticks like sh!t’ adhesive (hope it’s available in France!) and leave it to dry overnight before fitting.
I got something like that in the tool box, it even sticks plastic on car paint, I will try that if the lower one is actually missing, To free the horseshoe I did a bit like I read on this forum: a screwdriver in the pushroad hole in front of the engine just to feel the movement, and I pushed directly on the blade with my thumb. At first the blade was coming back with no response in the screwdriver so I pushed hard on that one, and the blade answered. Then I worked one to another, it took no long to make it work properly.

I'll be naming my next CD "Smoky and Capricious"...
Does it sound strange in english?

Well, I checked the chain last time I tried to unlock the horseshoe, it wasn't possible to lift it out of the cam sprocket even with the tensioner fully loosen. I unlocked the horseshoe quiet easily, now its moving free and the whole thing seems to be under proper tension... So i guess the bike have been rode without servicing but not long enough to do major damage to the pivot. The previous owner rode only a few hundred kms out of Paris with that 400. He told me the head gasket have been changed while valve gasket or guide (?) have been replaced, the bike was smoky and capricious. The job have been done by a friend of him, a "professionnal". I'm pretty sure he forgot tu fit the dampers back when mounting the head, I'm also pretty sure that no serious professional was in the place as the whole bike was a mess of approximatively done job. Nothing broken, just a bike left to unaware people. I've never seen smoke and she running great at first or second kick since I tuned her properly. I figured out the missing parts after I put back everything together!  Looking at cmsnl drawings, I saw the damper and I understand there is no damper in my bike, at least the top one!

Ok, thank you to make it clear, Julie!
My bike is 25000km old, around 16000 miles, the camchain should be ok for another 20000km, what do you think?
And if the bottom dampener is missing do you think I can stick it or attach it with a very thin copper wire or fishing line to the tensioner bow an drive it carefully in the horseshoe by the top of the engine?

Hi there!
I'm preparing myself to open my engine head cover and put the missing dampeners back in where they are supposed to be, at the ends of the tensioner bow. As i'm thinking about the damages it could lead to if riding to long without them, I struggle to understand why do we have to slacken the bolt to adjust the tension:
A/ As the camchain wears loose, the bow isn't pushing anymore because the pushrod is kept in place by the tensioner bolt?
B/ As I'm riding hard, the cam chain push against the bow that is forcing back the pushrod that stays here, kept in place by the tensioner bolt?
C/ Both?
D/ You can't understand my french gibberish!
help me please,
Cheers!

Something was bolted on there.
Maybe a wannabee Harley tool roll?
yep, or a luggage rack, that bike was once a ute
I love the way that CB400 four is translated as CB400 oven. Always makes me smile.
 only 400cc, it's a petit four! [ Guests cannot view attachments ]

Hi Nurse Julie, I was thinking about front number plate but screws should have been in line with fender, not across. The pitting points stopping straight in front of the screws prove that something was here...I will probably never know until she learns to speak french  I'm using Belgom Chrome on my chromes, WD40 left me a pale (white) film on them!
