HELP!! Yamaha Jetting Experts-
I am running a stock Yam 760 motor with a b-pipe dual carbed with stock 44's in a waveblaster 1. Carbs have new 1.5 N&S in them. Running stock airbox with chokes removed and 1 screen in the flame arrestors. Running 110 or 115 low speed jets and 125 or 130 main jets. Running 80 gram springs. The problem is off the line it hestitates, on the top end it is fine. When letting off the throttle and getting back on the throttle is feels like it is starving for fuel because it almost cuts off. Please HELP

What do your plugs look like. For some reason different jetting is ringing a bell. Reversed Maybe 120 lows and 110 highs? Are your anti siphon flaps ok?

Siphon flaps are okay. Jetting is getting close. Right now it has issues when leaned and or turning to the left. deep water starts with me in the water it wont pull up and out of the water.
 
I'm running a similar setup in a B1 I built last fall. I finally took it for a ride last week. It is running just fine with the stock jetting. This 760 came out of a Raider. It has a B pipe, MSD CDI, and an ADA Girdled head. Granted I only have one ride on the ski but so far it feels pretty good as is.
