OE cam spec comparison

[xlfan]

Does anyone have the cam specs available for 25486-93 and 25487-95 OE cams?

Sorry, don't recognize by part number. Nightrider has the specs for the 92-98 "N" cam on his web site:

Suffice to say that the stock cams are somewhat OK for low RPM torque, but run out of juice beyond 2500 or so. The cam profile is part of the EPA emissions control system so no (negative, actually) overlap.

Same with this calculator.  No part number. Just the years it was used if that helps.

Nobody knows where to find cam spec for the "O" cam stock in the 95-98 EVO EFI bikes?
