Spark Plug location

[dans58]

I am trying to do my own 12K service on my 2004 R1150R. I have most items complete, but I'm a little confused by the Spark Plugs. The dealer gave me 4 plugs . I have changed the ones under the valve covers (Yes, I was able to get the plug cap off). Now my embarassing question. If my bike has 2 other spark plugs, where are they?

The bottom of the cylinders. Straight up underneath.

Ah, the one place I didnt' look... I checked, and you are right. They are there. Thanks much, I'm back to finish the service....
