I have the rickest needle jet in right now. Obviously runs rich lol. Which one should I be using just as a ball park? Perhaps the original one it came with? I'm sure someone out there has a similar set up tuned and I'm curious what jets they're using to give me a ball park starting point.

Also when I roll on the throttle slow the bike pulls hard and is fast. When I just slam the throttle open it just doesn't seem to take off until it gets a second to start revving then off I go. Hesitation I guess. Is that related to my needle jet being way rich?
