Does anyone know what the difference between biposto, sps and r cams is ?
And compared to the 851/888 strada and sp ?

Take a look here Cam Spec's

Pretty good info. Some of the more "exoctic" bikes, specially the earlier ones could have one of a couple of spec's in them. Fairly rare to find but can happen. Must have been "friday afternoon" builds.
You should be able to double check what you have by looking at the cams them selves. The spec is usually engraved on them.

Thanks Nelly, I'd completely forgotton how much stuff Moto-One have on their site.
The graphs are very interesting - 851sp and 748sp with almost identical characteristics.
I can also see why the R has more midrange now, with about the same duration as the street cam but loads more lift. (Good note at the end of Doug Lofgren's article ! So I don't think I want one of those )

Well, after reading loads of moto-one's stuff ...
I definitely want to swap my 50mm Termi's for a set of 45s
AND
I want to know more about duc cam dialling !
(I've worked on my velo cam timing a little, but I'm sure that is childs play in comparison !)
Anyone got some vee-two cam pulleys for sale ?

G's are the race cams fitted to the hot 888's. 431's are a slightly milder inlet cam. I'll be fitting these to a 996 (that's in my 888) at the mo. looking for an 1994 corse 888 styleee but in a 996 guise. Alan (AJR) tells me it should be a ball to ride (with the Ti rod, balenced bottome end, Cossy, high comp pistons etc, etc....)


Rgds, Rob
