ok got a 03 banshee, T-6's, k&n with no snorkel and 10 vents in the lid. bought a jet kit and the biggest mains it came with were 280's. my elevation is 700 above and temp will be around 60-85. got the air screws 1.5 turns out and just bought 27.5 pilots. my problem is when i first start it, it smokes and wont run with the choke on. i have to hold the throttle, but once warm it idles fine but doesnt seem to smoke at all. right now im running yamalube 32:1 with 93 octane, but will be switching to klotz 40:1 next tank. i was wondering if i am too lean or something, oh and the needles have 7 notches and im on the fourth one down.
any help would be appreciated
