Just wondering where to place my probes? I've read anywhere from 1.5 to 6 in back from the head? Any advise?? It's going on an 02 rmk 700, if that makes a difference.

As close to 6" as you can get..
Not going to dispute this, as UoPK seems pretty knowledgable.

but will state this isn't an across the board number.
For different sled/pipe combo's this number may be different.

I'm using the stock Y pipe and I have place my probes about an inch back from the joint. Basically as far from the cylinder as possible, but before the exhaust streams mix. The readings I get, depending on conditions, vary from sometimes as low as 1100 at full throttle (was jetted way way rich out west), to 1425 (jetted too lean and was becoming very worried).

At least on my old 600 it showed that the leanest point really was about 3/4s throttle or so.
