Wondering when you change plugs on the RT?

I've just done a service and the plugs look fine, but at 23k miles intuition just says its time.

Would appreciate your thinking on this.

I changed mine the last time when the performance dropped off with about 15K miles on them when it began to misfire. The bike was fine up till that point. Past routine plug changes were at 20K and 18K.

Hi Hopz

Well the amount of sparks on the spark plug are really the determining factor not really the miles traveled. Miles are the easiest thing for BMW to have a person go by so that is what they do.
The plug gaps start out around .8mm or .031 and the wear limit is about 1mm or .040.
So as long as your spark plugs are not oil or otherwise fouled dont look blistered or have severely rounded electrodes and they look in decent shape they technically can go until the electrode gaps get to 1mm or .040.
Those BMW dual electrode plugs are a unique design electrode so need to be measured using a round or wire type gap gauge so get yourself a number 60 drill bit and when that will just squeeze between the side electrodes and the center electrode replace them.
Not much different than modern cars and some of them will go well over 100K on the original plugs and those usually have single electrode spark plugs.

My dealer bent me over to the tune of $20/per plug last time I bought them. Are there cheaper sources?

My local independent shop has a NGK Iridium plug which their book says fits the RT... $10 per each. Tempting

Thanks for the input guys. My plugs were the right color when pulled, the gap is holding fine. I carefully clean them with a wire brush and they still seem to have plenty of spark.

This plug:
NGK (7415) DCPR8EKP Multi-Ground Spark Plug, Pack of 1

is the one recommended directly from NGK's U. S. tech line for the R1200RT. I've used two sets, at approximately 24k each, and have had no problems. I also don't think they needed replacing at 24k miles. I'm going to run the current set until one of three things occurs: I get tired of the bike and trade; I notice a drop in performance; or, dang, I forgot the third thing.

Not hard to find, Amazon has them and will ship free; if you go to an auto parts store, use the "7415" part number rather than the longer one, if they can't find it under the longer one.
