the 50 pilot and the 370 main sound right. So does the 2nd clip. I would however change from 1 1/2 to 2 1/2 turns on the air screw. Basically, it sounds like it is set rich on the bottom. Turn the air screw out 1/4 turn at a time until it doesn't stumble at 1/16 throttle. Basically, warm it up and bring it up to about 4,000 RPM in second gear. Now, close the throttle and let it drop to about 3500RPM and whack the throttle open. If it wheelies it's perfect!If it hesitates and crackles, it is rich - so turn the airscrew out another 1/4 turn and try again. If it bogs (Buwaaahhh) then it is lean, so turn the screw in a quarter turn. When it is right, that bike will tool around at 1/16 (just a crack) open on the throttle with the sound of a bumblebee, not a crackling/popping (rich) or heavy breathing (lean) sound.
Good Luck!
