Paso cam timing
Given that the 906 Paso has a cam timing that is quite 'soft', has anyone tried putting a set of 900ss cams to the 906 engine? They have the same lift for inlet and exhaust but longer duration.

Re: Paso cam timing
Nope, as per my 906 instruction manual the 906 has an inlet/ exhaust timing of :
Inlet 20/60 Exhaust 58/20 (excluding Swiss model)
But the spec for a 1997 900ss is inlet/ exhaust timing: Inlet 24/70
Exhaust 59/29 see the next link (Andres Ducati 900ss homepage)
http://mysite.mweb.co.za/residents/an000003/ele2.jpg
Furthermore there is an article within this very website from performance bikes that states the the 906 cam timing is the softest tune from Ducati yet (1989).
http://ducatipaso.org/docs/906/articles ... -03-89.zip
So according to my information it would appear that the 906 has a softer tune than a 900ss.

Ducati belt-drive two-valve twins restoration and modification guide states:
906/907ie/900SS/E900/M900....................20°/60°...58°/20°
900SS (1994-1996).................................43°/85°...82°/46°
900 SS FE (1997-98)/M900S (1998-99)..........24°/70°...58°/29°
900SS (1998-)/M900 (2000)......................25°/75°...66°/28°
so it depends on the year.

The article (Very nice, thx f sharing! ) compares 906 cams w late 80´s 900SS cams.Furthermore there is an article within this very website from performance bikes that states the the 906 cam timing is the softest tune from Ducati yet (1989).
http://ducatipaso.org/docs/906/articles ... -03-89.zip
So according to my information it would appear that the 906 has a softer tune than a 900ss.
The markings on my OEM 907 cams are the same as carbed 900 SS/M900 w V2 heads.

Re: Paso cam timing
MotoOne:
I can´t say for sure what is right, just share the info I have.Although some people allege the 900 Carb cams specs changed for the ’97 and FE models, all the part numbers are the same. The listed specs are just different. The specs for the earlier 900 Carb models are 20/60, 58/20, which are not correct. These cams were also fitted to the 906 and 907ie.

Re: Paso cam timing
On the 2V 900, alot seems dependant on manifold lenght:

Re: Paso cam timing
ST2 cams are supposed to be the hot setup for the 900SS.
