D16 in for its 7000 mile valve service....all seems fine...clearances are what they should be...new DNA filter, plugs, shell advance oil and filter and fresh coolant...lets hope there's no bolts left over :)

You DO know that there are two more cylinders with eight more valves to check, right?

And that check is supposed to be done at 7500 miles.

Correct! Why would you even attempt work like this without removing the engine. For the sake of a few more bolts / saved knuckles / chipped paint work / and doing the job correctly... Seems a bit odd to me.

My 7500 mile service was done by the dealer, partly because I surmised (correctly) that Ducati might pick up a significant portion of it (10 hrs.) due to the fact that a couple of the closer springs had broken. One of the things noted in the service report was that more of the valves measured that they needed adjustment than were finally adjusted in the end. This was because the Desmo-Certified mechanic had the head(s) off and was able to clean up the valves and the seats and get them back into spec.

Now that I've seen these photos, when I do the 15,000 mile service I will leave the motor in the frame to CHECK the valves. If one/some need adjustment, I'll probably drop the motor and pull the head(s). Seems to me that once you get the airbox out, remove the exhaust and take the ass end off the bike, it's not a BFD to pop off the valve covers to check BEFORE you drop the motor. Re-installing the valve covers before dropping the motor is a total of eight easily-accessible fasteners.

Sure, you can likely swap shims with the heads on the motor and the engine in the frame. But might that NOT be what you SHOULD do?

If my valves need adjustment, I might drop the motor, pull the heads and take them to the dealer. For the price of three hours labor, I will not have to be the one fighting with Ducati to get the correct shims to install.

well Guys...thought Apollo was on a wind up....yes both covers are off...as it turns out no need to take the engine out as many people have said, only if adjustment is needed, and even then it can be done by releasing the engine and moving the bike back, doesn't need to be completely taken out.... checking can be done in the frame, my service due around now... 7,000-7,500 makes very little or no difference Apollo, and if you have a careful and competent mechanic should not have any damage, your more likely to damage more parts by taking it fully out in my opinion, any way valves all were within there tolerances. :)

Heads off Alice Breil no mate, why would you want to take the heads off or did you mean the rocker covers...its only a service check your manual most stuff is basic other than the valves no mention of removing the heads.

Any way all done for a while...down A32 tomorrow to Loomies to check her out with the new DNA filter, oil,plugs and fresh coolant...as mine has got extremely hot and even stopped twice over the summer :-(

Looking at this I see that the airbox was left in place.

To get to the front bank, the radiator had to be removed. The oil cooler drops out of the way and can be left connected.

To get to the rear bank, the gas tank, seat, battery & box, muffler with vertical pipe and rear frame section need to go.

Wondering, why were the front header pipes and the collector removed?

Checking the valves turns out to be a lot less complicated than the shop manual would indicate.

Interesting thread. And interesting to see and read the difference experiences of the 7,500 mile/12,000 km service. If it's useful, here is a run-down of my 12,000 km service.
The bike (#1445) went in mid-2011 to the dealership here in Singapore and fortunately the mechanic decided to take the heads off. He was being thorough -- I guess because he had the engine out and decided to check the condition of the piston heads and valve seats. Or he might of done a compression test and found an irregularity. I never asked him (he's a Japanese mechanic, specialising in race bikes) and he now works on oil rigs (my loss!).
I am very grateful he took the heads off. The carbon build-up was severe, several valves were no longer seating correctly and several valve guides were worn.
I saw the damage. Now this is odd because I am not a hard rider but the carbonisation of the engine shows the OEM race ECU runs very rich and things weren't helped by the bike not getting enough long rides. Singapore is a hot and has a congested roads (which is ride I only ride the bike on Sundays for the most part).
Ducati Asia decided to replace the heads and damaged valves (to their eternal credit). All in all, the warranty work cost US$20,000. I also promptly ditched the OEM ECU and replaced it with a Microtec M226 ECU and had it mapped to the bike. It runs on a map that is far less rich.
I now have 18,000 km on the bike. It still needs more long rides but I am hoping the 24,000 km service will be fine. I really don't want to fork out $$$$$$ for new valves or new heads. Time will tell.
Hope this helps.

What sort of fuel "economy" do you get?

I've kept track of the fuel on a spreadsheet since 125 miles.
Now at 12,600 miles, here are my stats:

33.7 Max miles per gallon, single tank (at ~11,000 mi)
19.4 Min mpg, single tank (at ~8,700 mi)
25.2 Cumulative avg mpg

To see how the fuel consumption is trending, I graph a rolling average of five most recent data points.
31.3 Max Rolling 5 data points avg. (at ~11,000 mi)

Hello Apollo. That's some impressive number crunching! I feel like a lazy git by comparison since I've never bothered to measure the bike's consumption in detail.
I know that on the motorway between Singapore and Kuala Lumpur I get about 10 km to the litre with fairly spirited riding (140 km/hr to 180 km/hr). It will do 130 km with less spirited riding and still have a couple of litres left in the tank.
Around town, consumption is still shameful -- it's very hard to pootle around town when you can make such a wonderful racket with a small twist of the throttle (particularly in tunnels!).
I will have to measure fuel consumption and get back to you.
