Plug colour reading - good diagnostic image
Hey chaps found this good image that may be helpful for others in determining where to read colours on the plug for jetting or timing issues.
It confirms what JustKDX's guide says in reading colour at base of porcelain with magnifying glass and torch, also to a lesser degree the flat surface where the threads end...... (for jetting readings) It was off a jetski website but can also be used for our wheeled fun machines |

I think the deposits left on the "flat surface" at the end of the threads is oil and fuel additive related.
Using the same jetting combo, if I ran Citgo sea and snow or Repsol synth2t, the "flat surface" would be brown. With Yamalube 2R, same jetting and mix ratio, the flat surface is totally clean. The piston top is also totally clean, with only a small heart shaped carbon deposit. The center of the electrode is dark brown. Bike runs perfect.

Without turning this in to an oil thread what 2t oil have you found to keep the PV the cleanest? |
