I am trying to get the jetting right on my banshee with my new pipes. When i pull the choke out, it doesn't do anything. I was wondering if this might be because i have too big of a main jet in. I have paul turner mids, pro design foam filter, no lid. I started with 300 mains and it smoke something fierce and it didn't run right. I am now down to 270's and it still smokes a little, but i don't have any low end power. I started with the clip in 4th position then moved to the 3rd and i really didn't notice much. I am in IL and it is cold out 30-40's. Do you think i need to keep going down in the main jets? Thanks
