First, be sure you still have the tiny spring that goes in ahead of the screw since that is designed to keep the tension on the screw and keep it from backing out on you.
Next, screw the screw     all the way in until it bottoms out ... BUT DO THIS GENTLY; just enough to be able to feel it touch the bottom.  If you crank it down like trying to tighten a bolt then the brass screw will be damaged and you will have to replace it.  It is not difficult, just turn the driver with your fingers instead of the whole hand.
Once it is bottomed out, turn it out (counter-clock-wise) 1.5 turns as a starting point and then go through the tuning procedure of finding the place where it runs the fastest (highest rpm).  When that spot is found, turning in or out from that position will cause the engine to decrease rpm.  You may have to to 1/8th to 1/4 turn each way in order to tell that the rpm is dropping.
IF during the process of turning the screw out you get to "3 turns out" and the rpm is still going up and there has been no point at which there was a rpm drop, then you need to go to the next larger size pilot jet.  If so, then after installing the larger pilot jet, start the process over with the new jet at the same 1.5 turns out.

NEVER GO BEYOND 3 TURNS OUT BECAUSE THE LITTLE SPRING IS ONLY MADE TO KEEP THE SCREW IN ITS' HOLE UP TO 3 TURNS, BEYOND THAT AND YOU ARE IN DANGER OF THE SCREW FALLING OUT.

I hope this is helpful

Thanks so much Lancer that was really helpful sorry i had to have you go through all that but i am still learning on the whole bike mechanics i have just now been riding for a year .
