dragbanshee02 Posted March 19, 2004 Report Posted March 19, 2004 " 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 OIT THEN YOU ARE NOW VERY CLOSE FOR FINAL JETTING... TAKE OUT AND RUN IT NOW.... ALCOHOL SPARK PLUG READING IS EXACTLY OPPOSITE THAN GAS........ TAN TO BROWN IS LEAN CONDITION..... WHITE TO GRAY IS PERFECT... IT SHOULD LOOK LIKE A BRAND NEW PLUG.... PORCELAIN SHOULD BE WHITE/GRAY 2-STROKERS-----ALL THE SAME AS ABOVE...DRILLING THE BRASS TUBE IS A MUST!!!!!!!!DO NOT FORGET THIS STEP.. BECAUSE IT WILL RUN....RUN AWAY THAT IS!!!!. IF YOU DONT DO THIS ENG. DAMAGE WILL OCCUR....WHEN YOU LET OFF THE THROTTLE, YOUR NEEDLE SLAMS SHUT IMMEDIATELY, WHEN IT DOES THE TUBE DOESNOT HAVE ENOUGH FUEL IN IT TO STABILIZE ENGINE RPM. NEEDLE WILL FORCE OUT ALL FUEL THEN IT WILL LEAN OUT...ENIGNE WILL START TO RACE UP VERY HIGH...SHUTTING OFF SWITCHES WILL NOT STOP THE MOTOR...IT WILL KEEP ON RUNNING AND RPM WILL KEEP CLIMBING UNTIL SOMEHTING COMES APART...IF YOU FEEL YOURS STARTS TO DO THIS THEN IMMEDIATELY PUT IN GEAR AND HOLD REAR BRAKE AND DUMP YOUR CLUTCH.....THIS WILL ALSO HAPPEN IF YOU RUN YOUR FUEL TANK OUT....OR FORGET TO TURN YOUR PETCOCK ON...IT WILL RUN OFF OF COMPRESSION AND NO SPARK...IF YOU DONT BELIEVE ME THEN GO AHEAD AND TRY IT.....(NOT ADVISEABLE THOUGH)..... ASK ANY QUESTIONS YOU WANT ABOUT ALCOHOL HERE..... TIM" Found this on another website how accurate is it? Quote
