how to centerline a dohc without a cam card

No idea why they are different (not OE and VE or OM and VM), but that’s how they are.Īgain, all timing is given at 1mm clearance (or 1mm lift without any clearance).

The cams from the 750 F1 and Bimota DB1 are marked OE and MV.

They have about 10 degrees less duration at 0.2mm lift than the NCR7.

DA06R49 is the DP “750” grind, to suit ‘85 on Paso style engines.

Megacycle do a modified version to, with tighter lobe separation from memory. NCR7 is an NCR grind, also available from Megacycle (USA) to suit the old Pantah style engine, 750F1, TT1, TT2, etc.So if you fit aftermarket end caps, make sure the inner step length, which locates the cam, is the same length. The later engines have a thinner journal here, which can lead to them being noisy if the belts are too tight, but also different end caps. There are two versions of this cam, due to the fact they are physically different at the LH end. DP DS1000 is the Ducati Performance cam to suit the 10DS engines.The Vee Two 300 grind is to fit the 1000 DS engine.The last couple have had 27/72 inlet timing, giving 14 degrees more duration than the specs show. In my experience the 212 grind is a little bigger than the specs indicate. My ST2 had these cams fitted before I got to it, so I have no before/after experience with them. The Vee Two 210 grind is referred to as a “torque” grind, whereas the Vee Two dyno graphs show the 212 grind to be a strong “top end” grind.See the “900SS CARB WITH SOME VEE TWO CAMS” report for results with this cam. It is the same as the Vee Two 210 grind, and is now found under the part number 964034AAA. ‘06090’ is the Ducati Performance 900 cam.The 696 seems to run the same lobes as the 1000 DS cams, but with the inlet advanced 4 degrees and the exhaust retarded 9.5 degrees, giving less lobe separation / more overlap.All others are physically interchangeable. You could make them fit if you really wanted to.

The 620/800 cams run in ball bearings like the earlier cams, but have two supporting bearings instead of three, and the location of these is different to the earlier cams. The 1000 DS (and now 696 and 796) cams are unique, running in the head itself without ball bearings. See the “900 2V ENGINES: NOT ALL CREATED EQUAL” report.

The small valve 900M engines used in non ‘Special’ carb models from ’96 sometime until ’99 used the 600/750 cam, along with 750 valve sizes.

These cams were also fitted to the 906 and 907ie. The specs for the earlier 900 Carb models are 20/60, 58/20, which are not correct.

Although some people allege the 900 Carb cams specs changed for the ’97 and FE models, all the part numbers are the same.
