Default read my plugs?

Are the plugs showing a rich condition? These are both from the front cylinder but the rear looked exactly the same. It was dry sooting not wet but it has been almost a week since she was run.
Thanks guys

put new plugs in , run it hard up to a high gear , when its pulling hard in say 5th kill the motor and pull the clutch in at the same time,
Roll to a stop then pull the plugs and show us.
That's a plug chop.
anything else is pissing in the wind.

It is impossible to "read plugs" and get an accurate determination of what air/fuel your bike is at. A bike may vary from very rich, to very lean, and back to pig rich again all depending on load, speed, rpm, weather, oil temp, etc.

From the looks of your plugs you are not getting the bike up to operating temperature.

If you really want to know what your engine is doing try this: http://www.innovatemotorsports.com/products/MTXL.php

Default read my plugs?

if you want a good read you have to do chops like mentioned, get it warmed up good, go out on a long stretch of highway, hold the throttle at the same speed for several miles, pull clutch, hold throttle, kill at same time, coast to a stop, pull plugs , that will give the best read of that throttle position, so do it at a speed you generally run , these bikes are rich on the bottom end and at idle so if you rode it slow to the garage and it idled, they will be black.

That is sooo cool, never knew that ..

I checked my plugs when still stock I just ride for half a day, "not slow but normal hard acceleration for half a day" and when switch off the bike NO idling.... but your way is cool too

my plugs were all grey / white so I decided to put more fuel and air into the motor

I know from watching my bike being tuned that a slight change in throttle position and RPM has an effect of fuel mixture not like the old carburetor days.
