Need a little guidance and info

[apfelbaum]

Hello all, my gf and I acquired a Ducati Monster S4R (996 motor) a few months ago. After riding the tires off of it for a bit it is time for the major service. So far here is where I am:

Oil change done
Filter change done
Oil strainer cleaned.
Timing belts changed
Plugs after the valve adjustment..

Now for the questions:

Can someone please give me the specs for the valve clearances (hopefully in mm, my feelers are mm) ? I didn't get the right manual for this bike from the dealer, in fact if anyone has the right manual I'll be happy to trade, I have the 07 model manual with the newer motor.
Is it better to make the adjustment with the timing belts loose or tight? (they are still loose)
Anything else that you guys can recommend while I have this thing apart?

I also plan on getting a vacuum gauge and checking oil pressure as well as sync the throttle bodies.

Thanks in advance.

Here's a link that may be of help.>Guide to adjusting Desmo valves.
<Mine,generally ,are set from .004-.006 inches clearance

Thanks so far, however, this is the only thing I have found so far:

"NOTE: 4v motors have a whole different set of clearances, on the looser side of the 2v. I am only listing them here as
reference.

Intake openers: .003"-.005"
Exhaust openers: .005"-.007"

Intake closers: .000"-.004"
Exhaust closers: .000"-.004" "

I'm not sure this is it. And it also doesn't state if this is to be done with belts loose or tight. When I convert these to milimeters I get:

intake openers: .076 to .127
Exhaust openers: .127 to .179

intake closers: .0 to .10
exhaust closers: .0 to .10

I know the Europeans like to work with more whole numbers so:

intake openers: .08 to .13
exhaust openers: .13 to .18

closers as stated

Does this seem right? I've found plenty of reference for the the 2V motors but not a whole heck of lot for the 4V motors. Anyone that has a 996 motor and has done their own maintainance, your guidence would be very much appreciated. BTW the info came from here:

Ducati Suite- Valve Adjustment

Again for the 2V motor, but everything should apply to my motor except for the distances.

Thanks again for any help.

This is what my 916/996SPS workshop manual says on page 62:

A) Opener
intake, mm:
0,05 ÷0,15
exhaust, mm:
0,05 ÷0,20

B) closer
intake, mm:
0,13 ÷0,25
exhaust, mm:
0,08 ÷0,20

Offer accepted, I was just about to get dirty again. However am willing to wait the 2,3 or 4 hours it might take to get here. Will have cold brews available if necessary . Yes, that was a fantastic page. But..begars can't be choosers. Haha, on a side note, I'm just going go with a number for the clearances that is in the middle and agrees with all the different numbers available for this motor.???

I'll be sure to turn things over real nice and slow before putting fire under it.

Might go with the MBP collets while you're in there. They will hold an adjustment much much longer than the split stock rings. All depends on how often you will ride I guess.
