They do fit, the extra bit on the end of the 950 cam doesn't interfere with anything in the later engines.

In case anyone's interested, I've got a set of 990 stock cams (the K601s shown in the photo above) that I should probably sell (too much junk, not enough room). However these are the least "desirable" cam judging by the research in this thread! In fact I've got most of a 950 engine in the corner of my garage ...

So do you have a set of 950 camshafts you want to sell which are in good condition with no signs of pitting.

Sadly no, the 950 cams are currently in use (in a 990 engine).

Wanted, a set of 990 Adv cams, want to try them in a 950 motor for more low-end mid-range torque.

I have a set of 950 cams that look good. They do have 60k miles.

I also have a set of pitted 950 cams, good for re-grinding.

Personally, I think the stock 990 cams are a freak of nature that might work well in a Honda three wheeler.

I wouldn't bother.

Long Term Update:

I continue to ride the wheels off my 970 with 950 cams and love it. I still have a set of SD cams sitting on the shelf, but the bike is working so well, I've had zero motivation to mess with it. I've just been changing oil and filters and riding it. Moved onto other projects...

I am cam ignorant and wondering whether the SE cams are the same as all the rest 950 model cams.
Also, if someone wants to improve on the SE cams, which ones should they use?
Would more power up top mean less power down low? How about the midrange?

The SE and the Adv 950 motors are the same. I'm building an SE-Like bike from an Adv 950 and want a really mild, torque motor. I rarely rev my 990 over 5000 rpm even on the highway. That's why I want to try the 990 Adv cams.
