I noticed a difference in my 950 when I rebuilt it with 990 cams. My 950 cams were heavily pitted and looked like lava stones on their tips, and 950 cam replacements had CRAZY prices on them, so I dropped in the 990 cams. To the eye, the 990 cams looked less aggressive in slope as compared to the 950 cams. The exhaust note on idle sounds less . . . choppy I guess is the best word. Just what you would expect from a cam with more "egg" shaped lobes. And my completed 950 now seems a little less aggressive in acceleration, which works very well for my riding style.
