Cct adjustment issues....

So after completing my valve adjust my stock cct took a dump the bike has almost 40k miles on it (2006) and I guess me disturbing its position was the last straw... so anyway I ordered an ape and installed it today, my engine no longer sounds like a tractor but it still has kind of a weed whacked sound. When I adjust the cct which is almost maxed out all the way in it's eaither tractor noise or a whirl noise when I rev. I've been playing with it for over an hour and can't find a spot where it isn't doing one of those things. I've only owned the bike for a about two weeks and ridden it twice, the bike had no strange noises prior to being taken apart. My question is if the cct is to tight would it be whirling while idling also or only on revs, the ticking noise goes away substantially when I tighten it more but I'm afraid of being too tight but any looser and it sounds like garbage.

I get the feeling on this forum that most people prefer to replace with new OEM rather than a manual due to how difficult it is to get a manual tensioner "right." Even the racers on this forum seem to go that route. I'm sure some will chime in soon!

Yeah I hope so, I also noticed the oem adjusts way further out than this ape so I may be manually adjusting the oem one lol

The shop manual should state what is a 'normal' range of adjustment for the OEM auto tensioner.....

If the auto tensioner is considerably further out than 'normal'..... that more than likely means the guides are worn. that's the only area that you can expect to see increased clearance.

Yeah I was thinking that as well I'm going to have to look into that next time I get a chance to pull the bike apart

The APE is pretty easy to adjust. Tighten it until the clacking goes away then 1/4 turn more. I run them on all my race bikes.

I measure exact length of the one being replaced, set the new one to that length then adjust slightly (when going to a manual tensioner)
but I do not get to a no noise point and go any further, if anything when it gets to "quiet" I turn it back a flat or two (there are 6 flats to the head)

But I 95% of the time just use a new oe tensioner as they have proven plenty reliable and mostly maintenance free

When you say the tensioner is considerably farther out than the original........ How can that be?
Where did all this extra room come from, the chains wear so slowly it is rare to see anything more than a few thou over seasons of riding. The guides mostly wear from overtightening of manual or eo tensioners (when dimwits adjust them), so how can this new tensioner just installed be so much longer extended than the one just removed?

How many clicks extended was the oe tensioner?

Stupid people say stupid things on the internet, so be wary of who those people are. If you solicit advice on the internet, just keep in mind 99% of what you'll receive is not based on fact or science-and likely atleast 95% of it is based on bullshit and bravado regurgitated from some other schlub who also did not experience any of what they claim and are also full of shit. If you don't like my bluntness- too bad. I am not here to please you, so move along, your approval is not desired nor is it needed. So before opening your pie hole and adding more stupidity, perhaps sit back, listen, absorb and learn something. You know that saying, it is better to remain silent and thought a fool than to open your mouth and remove all doubt!

Let me rephrase, this bike I purchased used about three weeks ago now and it has 40k on it, what I meant by the oem tensioner was that the part has the capability to extend about 1/8 inch further than the ape. I unfortunately do not recall how many clicks that unit had extended when it worked properly however I do know that it was only extending 8 clicks when it was making the terrible loose cam chain noise. When I "manually" adjusted the oem tensioner it had to be adjusted to about 11 clicks to be bearable to listen to. The apes max extension just barely reaches the 11 click adjustment of the oem tensioner. I believe the oem has the capability of reaching 18 clicks when maxed which is making me possibly return to the oem as the bike sounds like it could use a little more tension on the chain that the ape can't provide. Again I bought the bike with 40k and other than a chat with the original owner when I bought it I have no way to tell how the bike was specifically maintained prior to my purchase so I have no idea what may have been done up to this point.

But didn't you say it made no noise before you adjusted the valves and now it does? "the bike had no strange noises prior to being taken apart"

fyi--typical oe cam chain adjusters are only 4 or 5 teeth out....... if you are having to get it out around 11 teeth or more- there is something wrong that is not the tensioner

I completely understood the 40,000 miles and you only owning it a few weeks... you made that perfectly clear in the first post, just as you made it clear how it made no noise before you worked on it and now it does.

Perhaps a guide has been dislodged?

Yeah the guides are what I'm going to next, kind of a pain in the butt to see them but I'm going to make an attempt to check without splitting the case

Also I didn't check the or tensioner for exactly what tooth it was on ( I didn't have any reason to at the time) but I'm feeling like it was pretty far out it my memory serves me. II actually reinstalled the oem tensioner again at tooth 10 on purpose which was slightly less than what I had the ape adjust at and when I turned the motor over I heard the tensioner "click" and adjust longer. So it's looking like the guides are out of place or spent or the chain is getting old. So like I said before I'm going to have to pull the bike apart again and look at the guides. I still have a tick coming from the head as well so I'm going to recheck my valve clearances to make sure that's all in line
