Good Video, really appreciate you putting this together. I have a 2001 M900S4 with a 916 motor in it. I've done my own service including valves for some time. Currently doing the 30,000 mile service. Back while doing my 18,000 mile service I found the same thing with the cams and as a result 2 bad rockers. Guy Martin in Canada told me to do the same thing you have done except he recommended purchasing a 3M Scothtch-Brite wheel for my bench grinder with some advise to apply very light pressure while removing the coating. Guy said my valves would probably go much longer between needed adjustments as a result and they have. Have not adjusted them since removing the coating.
After years of riding 2 valves Ducatis, I'll buy a 916 really soon. Valve adjustment is easy on the 2 valves motors, I know it's a bit more complicated on the 4 valves engines and your tips will be very usefull. Thanks again !
Excellent, I'm prepped and ready to adjust. Did my wife's 8V 620 engine, I had .002-.003 on the closers, and .005-.006 on the openers. Very important to have have room for the oil to get under the closers cam lobes also, some folks say .001 on the closers... On now to the 4V heads, a little more complicated but not all than much more..
Hey, devildog5001 I live in Golden and brought my 996 up from TX last fall. Put about 1K miles on it and had a serious engine problem that will have me down for the winter. But we need to go riding when I'm back up and running next Spring.
hello help me please donot like I can tune my ducati disassemble to change cylinder segments and now remember that below cylinder guide me to synchronize
Could someone please give me some info on doing the exhaust side of these engines. I haven't seen a single video or post where where its mentioned. Nobody even mentions removing the exhaust. The reason I ask is because it seems damn near Impossible to do the exhaust side on the hor. Cylinder without removing the head. Thanks in advance for any tips. Also a great set of videos over all.
@@devildog5001 thanks alot man. It's my first time and I want to make sure I know what to do before I tear everything apart. I'm watching your videos and the belt replacement videos 100 times over before I start
Helpful vid Can you do one on cam belt adjustment? For the 748/916/996 of course as I really understand you . I think id understand the way you describe the process alot better comming from you
Great video I'm about to change cam belts & do valve checks on my 1999 ducati 996. Do u not have to get the valves re-serviced (cromed) after sanding them??
The rocker arm contact surface with the camshaft is the chrome he was talking about, the chrome that occasionally flakes off due to various reasons. Those rocker arms can be re-chromed. The camshaft isn't chrome plated. He is just polishing the camshaft lobe surface to a better finish, using sharpening stones.
hi Your videos are well done. It's interesting how to use the hexagonal key by find the closed value. I'd like share a trick, to remove fast the secondary shaft (8:20), you put a screw in the shaft and then by a plier, you can pull out without any problem ! ;-)
Do you have any concerns over removing the surface hardening of the cams?? Have you noticed any wear on the cams since polishing? I totally agree wit the concept but concerned I may trash my SPS cams!! They are no were near as bad as your but still rough.
I'd say wait until the end of the summer when I can do a fallow up report/video on my cams. As of 5/15/14 I have 3k on these cams sense I did this video, it won't take me long to get another 3k and then I'll pull it all apart and inspect. Mine were horrible as you can see in my video, there is no way I removed significant surface hardening with the amount I took off the cams to clean them up. The chrome plating on the rockers is your critical surface, without it you would wear your cams very quickly. Lucky for me if there is unusual wear on any of the cam lobes I've cleaned up stock replacement cams are cheap and plentiful, your SPS cams are not, I would be very careful with what you do with those cams. As you can see from the 'other' comments it's a controversial subject, but my cams were pulled right from a stock motor with 6k that had never been touched. You could see only the slightest amount of wear on the cams, all of the wear was on the 4 rockers that had the chrome removed. Thanks for the comment, and I'll keep you posted!
devildog5001 Can't wait to hear on the polished cams. Once I replaced 4 of my 8 opener rockers and set my clearances optimally on my 996, (.004 opener, .004 closer for me) I go 10,000 miles between valve checks. After 30,000 miles I've only had to replace 3 shims after my first 6,000 mile check/replacement. My cams and rockers are good!
Eku50740 I'm sitting right at 6k miles again and just need to find the time to tear into my motor again, hopefully over the holidays here. I changed my oil at 3k this summer and found just a couple tiny chrome fragments, so I'm really curious if it's a new problem with another rocker or just residual pieces finding there way to the pick-up screen. But I'll pull the cams and do a fallow up video for sure.
Axakias, I use Snyder's valve specs for this first time around. His are in line with factory Ducati with a lot of miles on bikes to back it up. If this link doesn't work google it, good luck and thanks for the comment. ducatitoolrental.com/uploads/Ducati_Valve_Clearances-2011.pdf
Those cams look dreadful. Ducati factory should have nixed those cams and put in some decent ones. Great job on the clean-up. As for chrome flaking off rockers...you are right about the poor quality chrome job and likely the pitting issue with your cams. Now other ideas come to mind, like using good quality oils of the right specs.... 20w-50 synthetic. And on any fresh, cold start-up, let the engine slow idle for at least 90 seconds before you ride it. That 90 seconds is supposedly just enough time for oil to travel up through long passageways to lube the cams. I've always done it on my 1999, 916 motor and have no rocker issues so far. Luck? A slow rpm warm up is king. I think it is unwise to start your engine with a fast idle, jump on the bike and blast away. If you shut the bike off and restart again, a 90 second wait is no longer necessary once you've ridden the bike to full warm-up. Enough oil is now where it needs to be to lube the cams until the oil is pumped back up top.
ok i am checking my clearance to see if need valve adjustment. watched your video and am following the the instruction from the following link ducatitoolrental.com/Ducati_4_Valve_Adjust_JLDS.html what i got so far on the horizontal intakes are .007" on both for the unload clearances, what should they be? i cant find the recommended specs anywhere. i get the loaded clearance to be.010" and .011" on them.

brilliant delivery! I was worried about doing this my self until I watched this video 2019 still relevant as f.....
did you remove the cams/ how long did it all take you? Need to do this myself and I'm real worried.
Great videos... I'm about to buy a 2002 748s expecting to be following these procedures. Cheers from the UK.
Thanks for all the info , Semper Fi !! Brother. Looking for a nice low miles 996 myself , looking forward to enjoying it myself !!

Dude... besides great taste for motorcycles, you have an excellent taste for music! 80s metal all the way! Bon Jovi, Kiss, Y&T, David Lee Roth... :D
If the chrome flakes off, I wonder if that's pitting up the cam lobes. Sounds very probable.

VERY useful. Really appreciate your time, here.

It's tight but there is room, no need to remove the exhaust. Same adjustment procedure as the intake side

Thank you very much for this video.It is what i have been looking for.Do you follow the ducati specs for the shims?
love your videos but I'm trying to remove my wiring harness my mid wiring harness from my Ducati 916 1995 do you know how?
sorry I've never removed the wiring harness, thanks for watching & good luck!

devildog5001 have you checked your cams since polish - how they looking after a few miles on them?

Eku50740 I just posted a part 3, check it out!
Your cam lobes need to be chromed or hard surfaced now, I believe, check out the Azzie, Bradthebikeboy, Brett (2002 S4)
