I'm running #128 with thicker needles not dyno needles, no airbox.... sp engine skimmed head, ported and gas flowed, stainless valves.
It pulls right through the rev range..no flat spots, and 75bhp

my 444 is running 115's go round the 118 or 120 mark for a 400cc ( 444 has more draw on carbs and amount of mix _)
