[sms_banshee]

Hello. I have a banshee thats bored 40 over with mild porting FmF exhaust k&n pod filters tors eliminator and boost bottle. I had it tore down for 10 years do to the infamous chain break. I switched over cases and put new seals and gaskets in it. I added the tors kit and pod filters during rebuild. My main jets are 290 pilots are 25 and the needle is 3 from the bottom and 4 from the top. I'm at 700 ft elevation. It has quite a bit of white smoke coming out and the plugs are pretty clean. I turned the air fuel screw all the way in and it helped some. They were 4 out. Its Not smoking near as bad and just from running a few seconds the plugs have a little color but I was afraid it may still be lean and didn't want to chance it. I'm wondering what jets and needle position I should try. How do I know if it's too lean to let it run for a while.
