My Cct's Are Going

Can you access the CCT screws to adjust them in any simple way?  My mechanical skills (and tools) hit the oil / air filter change, brake bleed / pad change high water mark so any job that includes "access the engine" sends me scurrying to the local wrench.  http://www.vfrdiscus...tyle_emoticons/default/wink.gif  By the sound, my CCTs are loose and I'm not anxious to toss money at a problem I may be able to solve.

The pics show the locations , I was able to adjust the front without removing the airbox( just had to unplug a few connectors, the rear I thought was more trouble(damn shield).  A small screwdriver is all ya need to turn them out. To wind them up and lock for removal ya need the tool.

but as you can see in the thread Turning them out really wasnt perfection, a slight improvement at best.

Ok a little update... front CCTL is bad. Riv, you were right about the hose clamps near the water pump, so I tightened them up. So I should have her road worthy soon. Thank GOD.

Good. Very good. Bet that's a load off your mind. Nothing worse than, "My new bike, needs new parts". (Actually, there's a lot worse, but you know what I mean).

Ive noticed the clacking on mine for a year or two, usually worse the warmer the engine is.

Finally replaced both CCT's this summer....to find the noise was still there the very next morning after i warmed it up.  Hasnt gotten any worse or better, and ive learned to ignore it actually, even though I really know something isnt right in there...

Is it possilbe the guides or chain has worn so much from them being bad, that now it just wont tighten up?  Or, have other things caused a similar noise to this on others' bikes?

Ditto

I did replace the guides, when I did mine.  <_<  By the way pressures are applied to them, it didn't make any difference. 1 of the guides had the nylon section, a TAD loose on it's "guide spine", (for lack of a better word). But no difference, like I said. The chain would have to be so stretched, slopped, that the bike would more than likley, run like crap. THUS the deduction of starter reduction gears. All of MY mechanical friends agree.

OK, thats kind of what I thought too.  I agree; that chain would have to be in such bad condition that it'd cause a running issue you'd think.

With this starter gear thing....how common has this been?  (Dont worry, i'll do a search too, lol)

Even doing a search, you prolly won't find it. (At least outside of my comments). Been try'n to raise awarenss, to get folks to check theres, but to no avail. Everyone replaces the CCTs, it works for a while, and,.......................................??????????????? The thing is, one has to take the sidecover off. That's a big deal, just to go, "Yep it could be them".   :unsure:   No-one has gone out and bought new gears, just to see. By the time I spent all my available $$$$, on the other goodies, I wasn't gonna buy gears, pins, and a new cover. The bike runs fine. The gears showed no wear. (Putting it more on the possability that when starting, the torque puts slight wear on the pins and the alminium cover, in which they ride).

Ok, well I need to change my damaged side cover anyways after my August 25th high-side, so hopefully it's something I can see when I'm in there...

You need a "special tool" to wind the CCT up...

You can turn the tensioner with a small flat-blade. The tool makes it easier to lock the tensioner when removing the CCT.

BTW new tensioner s come with the tool! :thumbsup:  

mikey, mikey. :unsure:

Yes,...BUTT, (That was for you, Kevin, LOL),................... There was a schematic of the, "key size". I'll make another later........... For those who just want to turn them out,.......

1) They don't have a key
2) You can't get to the key, without a pair of needle nose pliers, on the front bank.
3) One can use a straight slot screw drive, but most will not fit, (due to the screwdriver's tapers), and have to be shaped down.

Best suggestion, for those who just want to try turning them out, (and again, I'll get specs later), is to cut down a large blade feeer guage.

My freind Reddog took out his Cam Chain Tensioners (CCT) and was able to somehow put some more preload on the spring?  I havent see this done but he repositioned the spring on the shaft and it added more tension.  He was not sure he went too far so he PM'd me about it - first I have heard anyone doing that. The chain guides are made of a tough nylon so I told him it should be ok, but to check his oil next oil change for bits of nylon.  You might PM him and find out how he did it.  He seems to think that the spring stop slid out of postion and that is why his cam chain was rattling loose in the first place.
Thanks HS, here is the original post:

Finally getting around to checking my CCT, similar noises to what others describe.

I have the thing out and am messing with it. It seems the only thing that can "go bad" is the internal spring pre-tension. I have it apart and it appears that you can increase the tension and get it back together.

My fear would be too much tension? Or how much tension?

Anyone tried to increase the tension and re-use it?

*********The Next Day **********************************************

Well I decided to try "fixing" the CCT and it worked! The noise is gone.

I removed the cir-clip and removed the rod from the spring assembly. While holding the screw/spring assembly I turned the adjustment screw five times. While still holding that tension I put the rod back on (it screws into the assembly) and re-attached the cir-clip.

Of course now I don't know if there is too much tension, but the noise is gone.

Hmmm...should I leave it and save 70 bucks???

************* Today *************************

It is just the internal spring that gets weak over time. I have about 5K on the "adjusted" spring with no problems, noise is gone and all seems well. Could have spent 70 bucks on a new CCT but I had to ride that day. If you have the CCT out, it only takes a few minutes to study it and you will figure out how to adjust the pre-tension. You have to take it apart, and not just the external adjustment.

Pictures Please!   :goofy:
Yes they are very simple devices and I would agree it's most likely just the spring loosing tension that's causing the issue. I think I still have my original CTT's out in the shop and need to look at this again to see just how simple this mod might be!   :fing02:
My original CTT's went 32k miles (well at least the front went bad) and the replacement one's have close to 40k miles w/ no sign of issues yet. IMO the front is the one that wears out faster because of it's position/location.   :goofy:
BTW these bikes could rattle for years w/o causing any damage, but it sure sounds bad.   :laugh:
