Plug Pic - opinions welcome

So here's a pic of the plug on dirt bike.

 

It's a cheap and nasty 200cc Honda XR200 clone.

 

I fitted a 30mm carb and have been fiddling with the jetting to get it right.

 

At the moment I'm running a #100 main and the needle raised 1 notch off centre.

 

The bike idles really well and pulls well through the mid range, it is just a bit rubbish at the top.

 

The plug has hard white deposits on the strap and about half way round the end which would indicate a lean mixture.

 

I just thought I'd post it up to see what other peoples opinion is...

 

This is not a picture from a proper plug chop, it's basically after a ride around at full - 3/4 throttle for half an hour with a new plug.
