Bold part sounds correct to me. Thing is, I don't have a 630 so I cannot say with 100% certainty. Last I checked (2009) the 'power up' jumper was a 2,200 ohm resistor. Specifically if you put a 2,200 ohm resistor across where the sensor was plugged in, you will be 'powered up'
If you do that, you will ruin the lambda sensor. You may not need it anymore, but that's just money down the drain. If I were you I would just let your bike finish breaking in while you wait on the PU kit. Did you already pull the "restrictor" from the airbox? If you did, put it back in until you get the PU kit in, that should reduced some of the stuttering... Once you get the PU kit, the shop will probably re-map the ECU, which with IBeat is just a enrichment trim of low/mid/high RPM ranges, and you can tweak a few other things as well...
