How do i know if i need a new spark plug, i got a crosser (HONDA CR 85) and every time it trys to hit the power-bands it bogs down... it doesn't let me get the full power out of the bike? my mate said it could be to do with too much 2 stroke? would that cause the same problem? maybe the 2 strokes too thick?

what do you think the problem is?? what else could it be??

I do think its the spark plug personally as ive changed it before with the wrong 1 and it did the same sort of thing, didn't let me get the full power out of the bike??

can anyone help me
