Just wondering by removing the polution gear on my 05 450 what power gains are to be made. I have rejetted the carb that the spares kit supplied.(havent touched fuel screw) Unplugged the standard exhaust and airbox. YZ throttle screw. 13t front sprocket 50 rear Does the fuel screw make a huge difference, i would also like to keep the bike relatively quete. Keep up the good work.
