The CB900 cams sound promising! I hate to even say it...but I wonder what kind of gains you would see with that.Mainly how the torque curve of the engine would be affected.

Re-run, what you're saying does make the 900 cam sound like an attractive solution. Just to clarify, are you saying that the 900 cam is a drop-in for the DOHC?

What I've read elsewhere definitely doesn't make it sound like that's the case:



The fit issues mentioned in that write-up may be referring to the SOHC. However, I understand the stroke will be lengthened (article refers to using either shorter rods or some sort of spacer to compensate)
Can you verify that these aren't issues for the DOHC. I guess it would also be helpful for others if anyone could verify that the 900 cam would only work with modifications for the SOHC.
