my cousins banshee is about as bad as mine is lately..

 

His has a k&n filter, fmf fattys, powercore 2 silencers, boyseen reeds, and I belive thats it. Lid is on the airbox. snorkle removed, fmf boost bottle, b8res or br8es I forget which ngk plugs.

 

I live in PA, its really cold around here at the moment, it had 260 mains in it but it wouldnt idle or anything..

 

we put 250 mains in it and put the clip in the center position, bogged down pretty bad in the low end, leaned it out with the clip it hit the top still did it.

 

we put 240 mains in it, tryed center, still did the lowend thing, went all the way to the top once again, it still does it.

 

It idles pretty fast too, before it wouldnt idle at all and smoked like a train.

 

to explain to low end hesitation, say your riding it, it wont do anything till about mid it just bogs down and doesnt go anywhere, it pulls like a raped ape top end though..

 

Do I have to move on to a 230 main?

 

the plugs come out black they are getting better though, getting the vanilla chocolate color to them. between my 409 and his mine has ruined 8 sets of plugs, his is on 4 so far..

 

One plug fouled and it ran home on one cylinder, then it came back, then the other fouled, soo as you can see its been a pain in the ass..

 

Any help would be great me and him are pulling our hair out trying to get our bikes right!

way too lean you should be around 300 310 it rev high on idle cause it is too lean be careful cause it is so cold out so you should be higher than that
