Without speaking in poorly defined and confusing Stages 12345 (like my favorite woody stage 0.75), what is a good "not too aggressive" camshaft?  It needs to be a simple "plug and play" without requiring modifications and reworking (aside from some carb tuning).

Basic assumptions (is this even a "stage 1"):
1) stock air box, cover removed, hiflo air filter
2) stock exhaust head pipe, 17" open exhaust with baffle.  It's unmarked, no name, turn out style.  Appears to be a decently constructed “universal”.
3) Mikuni VM36 carb that would be dialed in for whatever cam (note: I like the responsiveness of the slide carb over stock CV carb)

A little bump up in the mid range would be cool.  I don't want some hard to start thing with rough idle or unpredictable WOT.  And, I'm not going for a bigger and/or higher compression piston down the road (unless I fry to break what I have).

Should I just stick with stock or is there something out there I should consider?  Why, what's it's benefit?

Thanks Dave.  Can you rattle off the names/brands of a couple you might recommend?  Or share a link?  If I do this, I don’t want to cheap out and buy junk.  I also don’t want to pay an arm and a leg.  Thanks.

Edit:  oops sorry, my scroll feature acted up and I didn’t see your entire comment.  I may be interested in your good used Webcam 466.  How good and how used?  I’m guessing the break-in period would be shorter in a re-install (yes, no?).  Why selling?  Did you outgrow it?  What could I expect from it performance wise?

A Stage 3 cam is designed for precisely that.  In comparison to other cams in general, this is slightly above a mild performance cam profile, just edging into the mid range category.  It enhances the best of the midrange torque the LS650 produces, while still extending the power range to 6500rpm and beyond if needed.  It does not stretch our engine beyond its capabilities, it enables better breathing throughout the rpm range.
Hiway cruising is easier, as is passing slower traffic and riding uphill, and acceleration is much more brisk.  Adding a 36mm VM carb adds to the responsiveness and power available if needed.

Added:  the Stage 3 cam has the same lift as the Stage 2, and the same duration as the Stage 1.  I settled on this arrangement because the Stage 2 moved the torque/power up in the rpm range to far.  It went up to 4500-8000 rpm.

I forgot to mention that installation and valve settings for this cam is the same as for a stock cam.  No difference … Easy to do.

Thanks Lancer and Dave.  That's great to know!!  It sure seemed extremely precision in their tutorial.
