The #105 jet is probably fine for now.
The carb SHOULD be set to 2 and 1/2 turns off of seat. So to make sure SEAT the mixture screw (turn all the way CLOCKWISE but DO NOT TIGHTEN!!!) then turn the screw out 2 and 1/2 turns. PLACE BIKE ON CENTER STAND AND THEN START BIKE. Then turn the screw 1/8 turn at a time COUNTERCLOCKWISE until you get HIGHEST RPMS, then turn the screw 1/4 turn CLOCKWISE and LEAVE IT. That should be proper AIR-FUEL RATIO. Then adjust the IDLE SCREW (screw on throttle, text to throttle cable) until the RPMS are as HIGH AS POSSIBLE WITHOUT TURNING THE REAR WHEEL. That's it, you should be good, have fun riding!
