My shee is lagging or acting sluggish before I hit the band. Feels like it's loading up with fuel or something. Mods are-

F.A.S.T. head 26cc domes .048 squish

+4 timing

V4reeds

Single intakes no crossover

CPIssb

35pwkS synced with tool 52 pilot 1.5 out, CEL needle 4th clip, and 160 mains

What do you guys think...

It's not coming on to the band smooth. It's loading up or something. Just wanted suggestions on what you guys thought. I'm thinking the needle is to rich. Was going to drop it to the middle clip. Maybe even drop the pilot. The bottom end seems weak for this setup. Maybe raise my compression will help. Im prettysure it's at 135+-. Going to test it tonight. You think that will help also? I'm not sure

Yea I plug chopped my bike with 9es plugs cause Jeff told me to but everyone says it's too cold for my set up and my plug chop left only half a dark ring around it so someone said the plug is too cold anyway. I'm going back to Br8es and going to redo my chop
