I replaced the B9EG plugs with a pair of BP6E-S plugs. Now I know the heat range is WAY too hot, I'm just experimenting on very short runs so I'm not too worried about a piston melting or anything.

Why would you do that? The NSR should be running BR9ECM's, unless it's an MC16, or unless you are running in extreme conditions, which you aren't.

You've not even answered Dave's question as to what model it is, but you are risking total meltdown even on a short run with those plugs.
