If the weather cooporates i will take it for a good test ride and then check the plugs. As for right now, withonly about 30 min of running time there doesnt seem to be any white marks on my plugs. They look normal i would say.

Getting the pc-v in a week or so.

Here is a pix of my plugs after 1K miles since I swapped the header pipes (from cat to no cat), and added the Rushes and XIEDs - front cyl on the left, rear cyl on the right. The insulators are definitely a tad "white," the side electrodes show "off-white", and there are some carbon deposits on the threads. On my old FXR with the T-header, cam, modded carb and hi-flow A/C, the plugs were just a little more tan in color than what these plugs are, and it ran great. Based on my previous experiences, I expect my F-Bob would realize some performance improvements and run better with a tuner, but that'll have to wait until I do a cam change. For now, the bike seems to run ok just the way it is, although I am sure some of the posters on this forum would differ on that.
