What year are the bikes? A high hr bike could use a float height check before making any jetting adjustments. Maybe worn needle / seat area.

  I'm sure there is some other info the guys might like to have before throwing some suggestions out there. 
   Air filter clean, Fresh fuel & Octane rating, Fuel/Oil Ratio, last top end service, Reeds, Weather, Altitude, has carb been cleaned, etc.
