problem with spark plug

[thopiang]

gentlemen

we were trying to tune a vixion packed t135, we replaced the old spark plug, then we run the engine, however, we cant get a good burn. the other side of the sp was colored dark and something white on the other half

what seem to be the problem? help !!!

bravely tinker my bike today, and checked my spark plug
this is it: is it rich or lean?

the pic resolution is insufficient...
i think its your valve clearance adjustment..all valve might have been miss the correct adjustment

 

[thopiang]

its a camera phone sir, my apology for the pic

the center color is like rusted color, while the ring or circle is color black

for T135, it looks rich

but it hardly tells u anything if ur bike is modded
