Has anyone done this? The 696 valves are 44/38.5, vs 43/38 for the 695 and 800 heads.
Given that I've damaged my intake seat, would changing at least the intake valves for 696 ones be a goer? I know the cams aren't interchangeable, but I could go to 1000DS cams and get almost exactly the same lift and duration as a 696, or even 900 cams for, well, more of everything...
I don't think the 1000ds cams will interchange as well as they are made simialr to the 696 cams. I have also heard that the 900 cams have a smaller base circle so you would need very large shims to get them to work. What about swapping a whole 696 head? Other than the change in location for the ECU oil temp sensor that is a possible option.
ian has some 44 on ebay now - italsparesducati
if you run original cams you'll need to shorten them between the tip and collet groove i'd expect.
are 695 8mm or 7mm valves? 696 are 7mm

I can't speak for all 695s (the service manual says they're 8mm), but mine (07 model) are definitely 7mm.
just ream the giudes to 8mm.
see, all my engineering has worn off.
696 heads are DS1000 style exhaust ports, so I suspect the 695 exhaust wouldn't fit.
But I haven't done it, so there you go.
696 intake is shown as 21010752B, ~$78 US, I was expecting about $100 more than that....
DS1k, all water-cooled Monsters, and all Monsters '07 and later are 7mm valve stems.
What's the difference with DS cams and ports? Are the corresponding valves longer? Shorter? If they're longer, I imagine it wouldn't be too hard to machine them to length and put a new closer groove in them...
Gotta say, I'm loving this. I checked my valves for runout this morning (I did it on our tool-room mill, with a 7mm collet), and they're between 0.02 and 0.04mm - Between that and the pitting, I'll just replace the lot. For the exhaust, I think I'll stick with 695/800 ones, but for the inlets I think I'll go for 696 ones. If they're unsuitable, I guess I could always just stick them on ebay.
DS/696/796/1100 heads have shorter exhaust ports, so the pipes are correspondingly longer, or thereabouts.
DS/696/796/1100 cams are plain bearing instead of ball bearing.
