Well my banshee, im installing new FMF SST pipes and Powercore 2 silencers, with a few other mods that are listed at the botom of my post.
the kit that i purchaced says that it comes with the required jetting. However, I have been reading and noticing that sometimes the jetting that is sent with a kit isnt the correct for the mods, so i anyone could help me dicide what kind of jetting to use i would be very thankful.

I will appreciate any help that you might be able to give.

 

Well, I don't know your elevation, but if your around sea level to 1,000', it's gonna be somewhere around 270 maybe 280 with stock filter. Take the lid off and you might go up another size on the main jet, like 280 or 290. You will want to go to a 27.5 pilot also and you might try the 4th clip on the needle, but without the added flow from the K&N, it might be just a tad rich. Your gonna have to go another size richer or so when you switch to a K&N also, because of the added flow, and I'd recommend to get a Pro Design Pro Flow plate with the K&N and get rid of the stock setup, it will eliminate any chance of the stocker leaking, which they're prone to do. With the K&N, you could end up at 320 or 300, just depends on your machine and elevation.

Not all banshees jet the same, so you still could be one richer, all anyone can give you is a baseline guesstimate and then you'll have to do some plug reading and listening to your machine to dial her in just perfectly. I imagine, FMF will be sending some 260s with it.

Just as an example, my banshee, when I had stock carbs, ran 310 mains, 27.5 pilots and 4th clip with FMF pipes, ProFlow kit, VForce reeds and the back 2" of my lid was cut off, and I'm at 600'.

 

I would guess my elevation is maybe close to 600 i live in south alabam but im really not sure what me elevation is.
Any ideas hos i could find out?

 

I used to know a place to go, but forgot. If your anywhere from 400 to 800, that jetting should work. Even if your at 1,000 it should work. We have a lake close by, and they always give the elevation of the lake, whether it's risen or dropped.
