The best way to know how to retune your bike lies in the sparkplug insulator color..
Clean out the fueltank and intank fuel filter/clunker inside the fueltank
Change your sparkplug...NGK BPMR7A plug gapped to .030"
In the center of the brass slotted screw on the carb rotator top theres a tiny slotted screw that may need to be turned counterclockwise 1/4 turn to richen the fuel mix....
On the side of the carb theres a highspeed needle...set it to 1 1/2 turns out
mix 93 octane fuel with synthetic 2 stroke mix at 40:1 ratio.......
start bike and set idle screw....
prop bike with reartire off ground...
twist throttle fully,,turn the hsn screw on the carb side in or out in slow small incriments til you get the rear tire spinning maz rpms then richen the screw up 1/8 turn for safety......

make some sort of mount, start the bike, give it throttle with one hand, turn idle screw with the other. then you gotta pretty much play it by ear and the color of your spark plug to get the right mixture and idle speed.
edit: there are tutorials on the forums for your carb, get reading. you will get a good grasp of how it works and what the different components do.
