two-tone spark plug??

[MXsandracer]

so today i do a WOT plug chop and the plug comes out TWO colours- one half reads a little rich and fades to read a little lean on the other side. so i ride it a bit more and try again but it comes up the exact same way. what would cause this? any ideas??

pics to follow..

after repeated tries this is the best pic my crappy camera would take lol

pic shows both sides of the SAME plug. its not so great of a picture and the difference is more dramatic than shown. anyone seen this before?

how long did you ride it before you did the plug chop?

the first time was after riding hard for like a half hour around the bush and up the fields..
when i treid the second time i let it warm up and then rode fairly hard for about 10 mins

guy you can tell nothing by "looking" at the plug a plug chop is not refering to the throttle being choped you must take the thread portion of the plug off and look at the base of the insulator..

I suggest you all read this thread the first few posts are about nothing really but towards the end of page one and on page two you'll start to get the point

I don't mean to come off as a know it all, but several times I have seen you guys refering to doing a plug chop and your not doing a plug chop

here it is enjoy Plug reading 101 - Page 2 - Dirt Rider . Net, Dirt Bikes - Motocross - Off-Road - Supercross
