I have questions about cat-code plugs. I recently went through the 0=0 routine along with throttle body sync. after replacing the throttle cables on my '98 R1100RT. I followed the Rob Lentini directions and others to the letter. even had to do it a second time to get it right, (just like predicted by the internet instructions. 
) Now everything is pretty good except for the idle when first starting up; I have to maintain a pretty high setting with the throttle for about 30 to 60 seconds before it will idle on it's own. I used the pink cat-code plug as Lentini suggested. But she seems awfully cold natured with it and even after a thorough warm-up of many miles, I get an occasional stutter when decelerating to make a turn or come to a stop. I have had to bump the idle up to around 1400rpm to keep it from dying at stops and rounding corners. I've read that the pink plug leans out the mixture, so now I'm wondering if it may be a bit too lean for the altitude where I live (~3600ft.) I never had these symptoms with the original mustard colored plug. I've also read that running without any plug puts the mixture somewhere between the mustard and pink.
My questions are these:
1. is there another plug that will remap the mixture just a bit richer than the pink one, but not as rich as the mustard?
2. does running without a plug truly make the mixture somewhere between the two I have tried?
3. does it matter which direction you install the plugs? they will fit two ways, 180 degrees apart.
Just to re-iterate; it runs perfectly at all rpms beyond idle to very slow. I ran it about 50 miles yesterday at a variety of rpms in all gears and used the throttle lock to make sure I didn't subconsciously adjust for subtle variations in the internal workings of the engine. There was no surging, no missing, no hesitation, no unusual vibration. Had good throttle response above 1500 and all the way up to 6500rpm. I let it hold steady at a given rpm for 3 to 5 miles at each setting. I'm
listening for more of the great advice I have learned to expect here.
thanks in advance.
