Need help reading plugs...

Sorry, this is also posted in images.

 

The plugs aren't really all that shiney in real life, but thay are definitly black all around, with mild carbon build up (not that much). Please help, I have no idea how to jet even though I've read all the post on it. Also, the bike idles too high, and when I give it just a slight touch of throttle, she bogs down, and if I hold the throttle just wee little bit open, like a few millimeters, she dies on me. What the hell do I do? NGK plugs, bpr7ES. FMF gold series 2 pipes. Boyeson rad valve reeds, wiseco pistons, mild bore, pro design air filter. Thanks.

not a problem man, no one knows how to jet when they are born. its easy once you get it. your air screw and pilot jet control the idle - 1/8 throttle, from roughtly 1/8 to 3/4 is controlled by your needle clip position and your needle jet(usually you dont have to change a needle jet) and 3/4 to full throttle is controlled by the size of your main jet. figure out where your problem is and that is what you have to change. you said just off idle it dies so I would see if you are way too right on your pilot. try adjusting your airscrew, then go to the needle and see if that is causeing the problem, are those plugs from a WOT stop or are they just riding and looking like that... They are way rich by the looks but a rich condition in one circuit can hide a lein condition in another so you have to make sure you are rich all over and not just way way rich on the mains and lein on something else.

look for a post by benbb and check out the "unofficial bansheehq jetting faq" click on that. it has everything you want to know about jeting a banshee...
