There's no problem so bad that a little fixing can't make it worse! : )
If it ain't broke keep fixin it till it is

Re: vavle adjustment question
by replacing both shims if need be, The addition of MBP collets is also helpful
there are multiply parts to that video shows exactly how to go about it

Re: vavle adjustment question
Let's try to tell you a summary of the jobrefering to the image linked:
a) measuring opening gap between #1 and #2;
b) measuring closing gap between #4 and #6 (forcing the spring #5 open)
c) move the piston to pms and remove the spark plug to help the job
d)pull out the axle holding #1 (a metric 5mm screw will do)
e)BE CAREFUL not to miss spacers and any other part next to the axle
f) every valve need such job so you'd rather to have a proper number of small boxes available to put shims apart (I happened to use the ones for 135mm photo film
g) go to a Duc dealer/workshop and ask for the correct shims and if needed, gasket

Re: valve adjustment question
Hi guys,
I recently joined the forum, since I bought my second 907, but more on that later when I find the time to introduce myself properly.
For the moment I'm giving my new 907 a big service, since it has sit in a garage (well, a living room actually ) for over 4 years.
One of the tasks at hand is adjusting the valves. Now, on my other 907 I've only adjusted the valves when I had the engine out on the bench, so now I have the following question for you guys:
What do you disassemble in order to do this job? Do you take the radiator off? airbox? inlet manifolds?
The cooling liquid has to be renewed anyway, So i was thinking of taking the radiator off anyway, but I hesitate to start taking off all the injection stuff.
Thanks,
Matthias

Re: valve adjustment question
Hi Matthias.
To measure the valve clearances its possible to do this with everything in place. Not easy, but not impossible. Once I had those figures, I then removed everything, Injection manifolds, radiator etc. The Injection manifolds are pretty easy to remove. Remove the airbox, disconnect the plug on the side, disconnect the throttle and choke (fast idle for the purists!), loosen the hose clamps to the ducts and it should all lift out as a complete unit. I have probably left out a few things to disconnect, but you get the drift.
Before you start removing any of the shims and what have you, plug up all the holes. There are oil gallery's in the top of the head which love to swallow little bits and pieces, such as the collets off the closing shims. Best thing I found for plugging them were a couple of ear plugs. just don't forget to remove them when you are done, or you will be sailing down that well known creek without a paddle! I also put a white sheet under the bike when I did it. Things tend to fall on the ground a lot, and the eye sight isn't what it used to be! As you spin the motor around to get TDC for each piston, oil gets pumped around too. So it catches that too instead of making a oil puddle.
If it helps, I got the shim kit and tools from http://www.emsduc.com/
They are good quality and work well.
One last thing, have a small magnet on an extension. Its very handy to get the collets out!
Cheers.
Nick.

Re: valve adjustment question
I also did the valve clearances on my 907 with the engine in the bike - fiddly but doable

Re: valve adjustment question
Thanks for the tips!
This weekend I got 'round to trying, and actually 3 of the four valve covers were reasonably well accesible. The only one I didn't get at was the upper cover on the lower cylinder. One of the bolts on this one is only a few milimeters under the retaining bracket for the radiator fan and the radiator itself.
I checked all the other ones, and they were +0.08mm on the opener, and 0 on the closer. The manual mentions it has to be +0.10 and 0. Since the shims only come in 0.10mm increments, I guess +0.08 is as good as perfect. For the last remaining valve, I think I will assume that it will not be much different than the others, and leave it closed for now. (as the official Ducati dealers mechanic too, told me he wouldn't bother in my place.)
On to the next tasks: new fork oil and coolant!

removing the fan should give you enough room, it worked for my tired fat fingered ass

Re: valve adjustment question
Perhaps they just wished they lived in Pennsylvania after all they had their thumbs out
Maybe they just pulled them outta their ass
