what size

[Penny's Banshee]

I will be running t5's and a kandn airfilter with outwears on filter and box cover. most of my riding will be at the dunes in pismo in ca what size jets should I go with

I've got the same setup but with K&N pods and I'm running a 320. I'd say since you're keeping the airbox maybe a 300 and see what that does. Be sure to do a plug check to make absolutely sure though.
