would the torque be in the 60's with the big bore or less??



My bike (05-790) with stock airbox (UNI - no snorkel), stock carbs (drilled slides and adjustable needles), and Specialty Spares showed a torque max. at 66 ft./lbs after the 904 BB. The best part is that it's above 60 ft./lbs. from the mid thirties through the mid fifties. Our goal was max. torque/Hp in the power accelerating range and we definitely got it. I'm using 125 mains and 145 pilot jets. It starts leaning above 6K, but going to bigger mains hurt the midrange. I shift by 6K to stay in my max. torque range.
