Quite a bit. The #1 arrow should be pointing level with the front of the head where the tach drive goes.
The valves would be hitting the pistons as you turn it over by HAND.
Perhaps the sprockets were installed incorrectly?

Damn... So this means that I have to do something that I don't know how to do LOL!

So the #1 arrow on the exhaust camshaft should be pointing the other way? How does the intake camshaft look?

I think all I would have to do is remove the timing chain then rotate the exhaust camshaft by hand until it is where it needs to be. Then reinstall the chain.

This must be another reason why the damn thing doesn't run .

You should be able to determine something by checking the valve clearances as they exist with the crank in this position.

use your feeler gauge on the valves and see.

oh and do not panic
have you actually started this thing?

How are you going to rotate the cam with your spindly little fingers.
They will be acutating valves, I tried on my wee 550 and could not move one. But I am old............

Proper alignment of the cams is with the notches pointing towards each other, with 3 and 2 poining to 12 o'clock, and 1 at 3 o'clock or flush with the gasket surface and 20 pins between the 3 and 2 including the pins that the arrows point at.

Rotate the crank again clockwise till you are back at "T" till the notches on the cams are pointing IN toward each other, then you can see the arrow alignment is correct and or how far off you are... should look like this:



If you are getting any resistance (valves hitting pistons) when you turn it, Stop. You'll have to remove the cams and realign them to prevent any damage.

T mark is aligned.


Intake camshaft.


Exhaust camshaft.







Looks like it's off by maybe one or two teeth. How do I fix that?

I will not rotate this any more.

[JEEPRUSTY]

you would need to remove a cam at least on my bike you would.
But you are in very good hands with the prev poster.

Dont you have the manual I just finishe dloading it from chez clifford.

but the intake looks like it is back one tooth

How would I remove the camshaft with the cam chain there?

I do have the manual. I will look.

Manual says it pretty straight forward and would take me longer to type out

Engine section 7-17.

Fairly straight forward but if you have any probs shout.

Disengage/remove the tensioner first, then loosen the cam caps progressively, remove the intake cam. Realign the exhaust cam keeping the cam chain taught by pulling up on it, replace and align the intake cam. Tighten down the cam caps, engage the tensioner, rotate the engine and recheck alignment.

Thanks Nic. I'm going to do it right now. Be back in an hour or so!

[niclpnut]

Cool,


Remember, after you have the cam timing adjusted, don't forget to check valve clearances. They are probably going to be way off.


Nic

[psyguy]

your cams are off by one tooth by the looks of that pic above. you need to take the cam caps off to be able to rotate camshafts independently of the chain. dont let the chain drop into the cases while you're doing this .
cam chain tensioner has to come off as well.
wrong timing explains hard starting.

I corrected the timing then tried to start it. Same as before. I will check valves tomorrow.

Renewed the CCT gasket.


Exhaust caps removed.


Not the best picture but it should look like this right?

[JEEPRUSTY]

So you didn't set the valves?

And now we have to wait till tomorrow.

no No No I need to know the outcome now
