i'm putting together a list of camshaft id markings (numbers, letters, etc). anything anyone has would be helpful. i don't really have anything from 748R onwards.
These aren’t easy to come by!VA-3771A - 223
VS-3591B - 42
OA-3761A - 204
OS-3581B - 44
The numbers after the VA etc are the last section of the respective parts #s. The 2 & 3 digit #s after that I don't know
I believe thebetter ms were originally used in the 996R. They are the same spec as the 998S and 998R. The R had high compression for a bit more HP. the 1C cams would not be original in a Biposto but would have been fitted later.
I have a 998 Biposto and have some 1C cams (from ebay as 996R cams) cam to install next time I check the valve clearance.
The R in OA - A1R is the revision made to undo the rev counter from the older bikes, same lobes still.i'm putting together a list of camshaft id markings (numbers, letters, etc). anything anyone has would be helpful.
