tighten with finger is to determine contact point, not actually to crank on with any degree of strength once contact is determined.

LAZN- I have removed the old cct and installed the manuel rear, I did not hear any clicking or indication of jumping, is there anything to see visually looking down at the chain to tell if it has jumped or not? would it jump at the top or bottom? Is there anything else to check before moving to the front? Thanks.

Did you remove the valve cover? If so, and you are at TDC compression you should be fine.. Now just rotate the engine 450 degrees counter clockwise before doing the front.

did you read my write up? http://dl.dropbox.com/u/219618/cctwt.pdf

Yea, we followed it to a T. just finished the front and spun the motor 3-4 times, did not hear anything out of the ordinary. Is there anything to listen for?

Just finished doing this as well, and man that front cover was a PITA! Also checked my valves while I was in there, and happily all in spec.

I keep reading three different takes on the adjusting of the Apes. The auto tensioners when I removed them put a decent amount of pressure on the chain, yet some say finger adjust until contact and nothing more? I've also heard it has to be running when you do it, or if you are at TDC (which weren't we all?) you can adjust it while its off.

Are these all just opinions, or is one the right way? Mine is finger tight -1/4 turn while at TDC (the no lobe contact one) not running. Much more work to do before I can fire it up so won't be running for a bit.

Nope, nothing special to listen for.. No valves meeting pistons etc. If you did not hear a loud click when you removed the OEM ccts (the chain jumping a tooth or two) you are done.

Pretty much all just opinions. Unlike the OEM ones, unless you really messed up when you installed the APES, it is all a matter of how loud the mechanical noises your bike makes while running.. Even if it is "too loose" if the retaining nut is properly cinched down you are not likely to have a catastrophic failure, just a noisy bike. (you would want to fix it, but unless it is not even touching the chain it should still prevent the chain from falling off the cam sprockets)

Way way too tight can cause problems too, but I have only heard of that happening once to a member that had a shop install them for him.

Great write-up, I followed this and it worked perfectly. Be safe, use the zip-ties to hold the cam-chain on the cam-sprocket, great idea. I have yet to run the engine to test it.

I could not find a torque setting for the CCT mounting bolts (the two allen bolts that hold the CCT to the cylinder head) in the Honda Service Manual, but the Haynes Manual lists it at 23Nm. I used blue lock-tite on the threads.


An update from APE on the adjustment procedure. This was on the back of the APE package:

" ----> Instructions <----
To set the tensioner adjustment, rotate
the engine forward while screwing the
tensioner in. When you feel the engine
tensioners parts (guide, rollers, etc.)
make contact with the moving cam chain,
back the tensioner bolt up 1/4 turn and
tighten the jam nut.

*** CAUTION ***
Do NOT over tighten cam chain, as
cam chain damage could occur. Be
sure jam nut is tight against tensioner
body when complete."

Went APE today following these instructions and it went like a breeze. I was fortunate enough not not have the "click" of death. The only hitch I found were with the instructions for adjustment. Apparently "finger-tight" is a very subjective term when you have hugemongous dick-beaters like I do. I had to loosen the things up a bunch to get them to stop squealing. Great walk through on the instructions.

I guess finger tight actually does mean finger tight in the sense that you feel with your fingers that it's snugly up against, where it stops, back it off, where it stops, back it off, turn in til it stops. Amen.

OK. I need to double-tap this with a (dumb) question for my clarification...

I want to switch out my stock CCTs with APEs since my bike has 24K on it. But I literally just changed my oil. I assumed I needed to drain the oil if I was going to replace the CCTs and open up the valve cover. Can someone confirm that I can do this without draining the oil?

And how often should I check/adjust the manual CCTs after installation?

PS: Awesome post by the way. I'm learning a ton about my bike. I'm a mechanical noob.

No need to drain oil if you remove the valve cover, just make sure you don't dump crap down into the motor.

I would check them once a year or if you hear odd sounds from the valve train.

Screwed

telescoping magnet, blow some air down there to move it around if you need to.

Remove the oil pan...... Sorry but that is where it is and you will never find it with a magnet. The good news is there is no oil pan gasket, just RTV. So bite the bullet, drop the pan. While you are in there pull the oil pickup (it's just held in with a "o" ring and pulls right out) and clean the screen.

What to ask me how I know these things?????

When you line up the "RT" to the index mark in the timing hole where are the marks suppose to be lined up if I'm looking at the cam's (this is the rear of course). I'm afraid I've messed up the timing (a little too ambitious) Just wanna absolutely positive. I hope this makes sense.

So what have you done so far?

RT lines up with the mark twice in the 4 stroke process, so there are two possible answers to your question.

If you are on the Compression stroke you want it to look like this:

I'll take a pic when I get home... maybe it will explain things better and help me get my bike back together. Have you replaced the oem CCT's before Izan?

Yep, if you click the "APE CCT" link in my sig you will find a PDF I made of my adventure in replacing the CCTs.

Nice wright-up! I do well with pictures... I know for a fact that I fudged up the timing. If you don't mind I'll send you a pic to see if you can tell me what the damage is. by the way I haven't touched the front cylinder yet... that should still be fine right?
Sorry if I'm asking to many questions.

So did it just jump by a tooth or two? Or did the cams totally spin?

If they are just off by a few teeth you can just loosen the CCT and "inchworm" your way back to the correct timing. If you are a long ways off, download the service manual and look through the reassembly process for replacing the heads, as it has how to time your cams in that section of the book.

Manual available here: https://www.superhawkforum.com/forum...ad.php?t=11365

Got'er done!...
It did jump ahead quite a bit I had to remove one of the cam sprockets to re-align... yikes! I just made sure to take my time and also study the manual an that awsome wright-up Iazn did APE CCT's
Now she's back on the road!

As you can see by the previous post I got the Manual CCT's in! However with the "finger tight" then a 1/4 turn the front cams still seem to be slipping (click and lurch) every so often... not as much if any when the bike is at operating temp. So does this mean I need to go tighter? Anybody?

They better not be slipping.. Your bike would barely run once more than a few teeth slipped, and it won't slip back into place so then the next few slips and your engine would self destruct.

It may have slipped while doing the swap, so you might be mistimed by a tooth or two, and that will cause it to run poorly.. but if it were actually actively slipping the bike would not be long for this world.

(that doesn't mean it isn't worth adjusting them some.. What you can try if you are careful about it is adjusting them with the engine running. If you search you will find the procedure for that, I didn't want to risk it though when I did it)

My guess is you are experiencing the famous "carb fart" I don't recall the procedure to fix that one though.

Well the bike is runnin' just fine and sounds great... So as to what that noise and hesitation while riding is I have know idea. You did mention the "carb fart" does that seem to be a common issue and would it give you that hesitation (more like a lurch) feeling while riding?

Just in the process of putting the top end back together after adjusting the valve clearances on my '98 VTR. Cams (Yoshimura stage 1) installed and timed per the Honda repair manual procedure.

I considered installing APE's but decided to install new OEM CCT lifters instead. Never had a problem with the original ones after 56,000 miles, so replacing these is just a preventive measure. Prefer not to be bothered with maintaining cam chain tension manually.

Apparently the '98 to '01 CCT lifters were superseded in '02 with a revised (and improved ) design according to what the dealer advised.
