I have been having a heck of a time getting my bike dialed in. It pulls awesome but is breaking up on the top end. I did a plug chop pulled the plug it was dry and kind greyish brown with specks on the insulator. I went to up 2pts, 4pts bigger main no diff I am thinking its lean but maybe im wrong any help would be awesome I am pulling my hair out. Heres some pics of plug after chop if that helps.
