FOUR STROKES-----FOR THE WAY YOUR BIKE IS AT THIS MOMENT, THIS IS WHAT YOU NEED TO DO....GET A GOOD NUMBER DRILL BIT SET....REMOVE THE JET YOU ARE CURRENTLY RUNNING AND SLIDE IN THE DRILL BIT THAT FITS THE BEST..SNUGGLY NOT LOOSE...NOW MIC THE DRILL BIT....(EXAMPLE)- IF IT MEASURES .050" THEN YOU NEED TO DRILL IT OUR TO .100"...
GET ALL SHAVINGS OUT...NOW TAKE YOUR NEEDLE OUT OF THE CARB. AND MIC IT LARGEST DIAMETER JUST BELOW THE CLIP GROOVES AT TOP.WHATEVER IT MICS THEN YOU NEED TO DRILL YOUR NEEDLE JET (BRASS TUBE IN CARB).022" LARGER. THIS IS A MUST!!!!!NOW PUT YOUR CLIP IN THE HIGHEST POSITION.LOWERING THE NEEDLE ALL THE WAY DOWN...CHECK YOUR SPECS FOR FLOAT HEIGHT AND MAKE SURE YOUR IS CORRECT BEFORE YOU REASSEMBLE YOUR CARB. IF TOO LOW YOU WILL SUCK YOUR CARB BOWL DRY...NO NEED TO MESS WITH PILOT AT THIS TIME....DRAIN GAS. NO NEED TO FLUSH OUT. PUT IN YOUR METHANOL/ALCOHOL...START ENGINE...IF IT WILL IDLE, THEN NO NEED FOR PILOT TO BE DRILLED...IF IT WONT IDLE AT ALL EVEN AFTER IDLE SCREW ADJUSTMENT, THEN YOU NEED TO TAKE BACK OFF AND REMOVE YOUR PILOT AND DRILL OUT ABOUT .008" - .012" OVER STOCK.DONT GO OVER .012" IF IT STILL WONT IDLE THEN REMOVE PILOT AGAIN AND DRILL TTHE CARB BODY.008"... THIS SHOULD IDLE NOW....NOW REV. FULL THROTTLE FOR A SECOND..IF IT SOUNDS LIKE IT RAN OUT OF FUEL THEN COMES BACK IN AGAIN THEN GOOD.... ITS NOT RUNNING OUT OF FUEL... IT IS ACTUALLY WASHING THE SPARK OUT....
NOW YOU NEED TO START GOING SMALLER WITH YOUR MAIN JETS. GO IN .005 INCREMENTS...WHEN IT REVS AND KEEPS ON CLIMBING WITH NO SIGN OF CUTTING



ive read all of this...but what is the pointt of drilling my YOUR NEEDLE JET (BRASS TUBE IN CARB) .022 larger? it said some where else so that when the slide closes it dont shut all fuel off.. but thats where the piolet comes into play and the largest part of the needle under the clips doesnt go down far enough to completely just off fuel...sooooooo...i dont think im going to drill my needle jet.

 

If you dont drill you needle jet, you will not be able to flow the amount of alcohol you need on the top end.
