Before I touch anything! - Engine gurus

So, got it peeled apart, to check the valve situation out--

I took the CCT out, before popping the valve cover (see now I shouldn't have).

Now, this is what I'm looking at. I could be stressing over nothing, but before I touch anything, looking for some guidance.

As you can see, the chain is off one of the cams, that's how it was sitting when I pulled the cover.

Now, when I stick my finger in the cct hole, I can take the slack off, but, not enough to pull it so it's tight, and locked in. But, when I let the slack go, it falls nicely into place. (see photos)

What do you suppose I do here. Is this something that will pull together when I put the new cct (manual) in, if you understand what I'm saying.. Or, is this something I need to deal with now?

Any more info I can provide, to help you answer, just ask! Am just being cautious, not touching anything, before I know exactly what I have on my hands. I'm not experienced with anything inside the engine, just know enough to mark, and put everything back exactly the way it came out, and the steps for checking my clearance. Everything else is a new language.

Thank you for any help!!

Here's what's going on:











Something tells me I either need to crank the motor, to make it fall in place, or, when I put the tension on the actual tensioner, it will pull it into place, but I'd rather not guess.

What do ya figure?!

Thanks.

I took the timing cover off and just held tension on the chain as I tightened it. when you are tightening the cams down watch the chain to see if its coming off the sprocket. If it is tighten the opposite side of what you're doing

Ok. That makes sense.

But, when you had it apart, was it sitting on top of the cam like that?

And as you did tighten the chain down, did it pull into place?

Like, I feel like it would turn the motor clockwise ever so slightly, that it would drop on.

:confused:

AS Long as I kept tension on it and tightened the cams down it fell into place.

Canada must have gotten pretty boring as Winter sets in!!! :laugh

:laugh Ya.. It's an 06 R6. Sorry aboot that. :laugh

I took my nighttime medication, so I'm only on 1 cylinder right now, and can barely even move to type this, so try to stay with me. :)

After watching an EXTREMELY helpful vid of a lad tearing down, and showing how it's all done. I think I know what I need to do, and your pictures up there make perfect sense!

I think I was just caught in the, everything needs to be marked, and put the same.. But.. Not really. My timing seems to be out.

So, I'ma get that whore to TDC, yank the cams out, do my valving shit, then, when I put it back, make sure it's still TDC, align the cams as per what the fcuk they should be, throw the chain on so the slack is only on the back, where the CCT is, and stick the CCT in, and give it a couple turns, and make sure everything is where it should be.

That sound aboot right?

(Again, if I sound like I'm not making sense, I apologize. This medication really effs me up.)
:yes

As I read the posts and saw the pictures I was dying to post that your cam timing is more than likely lost and now you need to do exactly as you post. Cyl 1 to TDC and re-time the cames. You should cop some adjustable cam gears and advance 1 degree the intake cam... :popcorn: Bottom end is for pussies anyway. :laugh

J/K, I have no idea if you'd have valve to piston clearance if you did that. :laugh

Sounds like you have it. :cheers
Good times bro, good times.....
:drink: :pimp:

I see you have GSX-R in your "bike" section. What is the year and model? You see the line on the front cam sprocket? That is the timing/alignment mark. That is suppose to be even with the head with no.1 cyl @ TDC. There is on on the rear cam sprocket too. Crank and both cams must be in the proper place or you fooked!

You can find the manual for your bike from here: http://www.servicemanualsgsxr.com/category/suzuki-gsx-r-600/

Look for the "camshaft" section of the "engine assembly" section something like this (from 01-03 models, different years is different but fairly similar procedure):

:lmao Good way for me to waist my 1,000th post......
Either way, cam alignment procedure is very similar between models. Just check the shop manual OP.

Noticed in the second pic your timing cover is still on. Take it off and it has timing marks to get it at tdc then align the cam marks with the cylinder head.


Btw was it a pain to get the engine out? I left mine in when I do valve checks

Either piston is hitting the valves or you're feeling the compression (if the plugs are still in)

Oh ive had that feeling to often. When I was 13 I decided id rebuild the too end in my 250. I reused a 25 cent cir clip instead of getting new ones. That clip cost me almost 2k in the long run. Destroyed my engine

Its simple you're just over thinking it.

retime it and take you're time. Make sure all the marks are aligned and you're good.

Out of curiosity, do you think it's possible I can't turn it when It's all bolted down, because it's in gear?

I'm at work, or I'd try.. :laugh

I feel like I'd know if there was a bent valve, is the thing. You may be right, just over thinking it. It worked just fine before, and I haven't touched anything. Should be fine.. Friend came over last night, and said the same.

The valve clearances are way out to lunch, so that could have been the knocking noise.

even if you DO take the head off, if you can't set the timing on the 2 cams properly, you're fu ck ed.. just later than sooner this time. and yes, if it's in gear and you turn the motor over at the crank with the 12mm socket, the rear wheel will just spin. If it's not turning over something is wrong. you need a manual. cap bolts for the cams need torqued down in sequence. And i suggest not pulling the head off just yet.. if you do, get a new head gasket before hand and those head bolts FOR SURE need torqued down properly.
