Question about Suzuki Motorcycles
Make sure the battery is fully charged and check your charging system to make sure you are putting out 14 volts or so. If yes then check the spark plug wires for defects, then check the spark plug itself if black or wet looking then it may be from a fouled plug or weak spark. If you can switch the coils to see if that has the opposite effect.

SOURCE: throttle bog out
hi,this may help,check the inline fuel filter and the air filter,if it has been sitting that long the fuel filter may have gummed up(a slightly gummy residue left behind after fuel evaporates) the engine will run ok at low and medium throttle but the filter will be quite restrictive once the load goes on,change the filter and clean the air filter and you might find the problem disappears...hope this helps...cheers

My bike started doing the same thing. I pulled the carbs put new kits in them and it still does the same thing. It does not seem like a spark issue because the fuel consumption would not be this bad, but the floats looked good. The needle valves and seats are new. I am not sure what to think at this point. I even replaced the intake manifolds and flushed my fuel system. It starts good initially. It is almost like the fuel pump is pushing to much pressure and over coming the needle valve. Has anyone seen this before?

Did you sync the two carbs? If not the rear may be getting all the gas from the rear carb and none to the front. Twist throttle engine off and see if front carb cable is pulling the carb open.
Also unscrew the spark plug boot from the front spark plug wire and trim 1/8th inch off the wire and screw the boot back in. The plug wire end may be corroded on that wire.

HI A TWO STROKE NEEDS ONLY THREE THINGS TO RUN, WITH THE EXCEPTION OF A POINT GAP AND CORRECT IGNITION TIMEING,
3 MOST IMPORTANTLY IS COMPRESON,
IF YOU HAVE A SPARK THEN I WOULD NOT SUSPECT A COIL THEY EITHER WORK OR THEY DONT WORK.
IS THE PLUG GETTING WET ON THE CYLINDER THAT DOES NOT RUN? IF YES THEN ITS NOT A FUEL PROB, IF ITS NOT THEN IT COULD BE A BLOCKAGE SOMEWERE, WHEN ITS RUNING PLACE YOUR HAND OVER THE BACK OF THE CARB, YOU SHOULD THEN FEEL SOME SUCTION, DOING THIS WILL RESTRICT THE AIR FLOW AND PULL FUEL UP THROUGH THE MAIN JET, ELIMINATING A FUEL SYSTEM PROBLEM ITS HOULD THEN FIRE AS YOU HAVE FORCE CHOKED THAT CYLINDER ONLY, IF IT FIRES QUICKLY REMOVE YOUR HAND AND ALOWE AIR FLOW, IF IT DOES NOT FIRE YOU MAY HAVE A COMPESION PROBLEM, REMOVE THE SPARK PLUG, AND USE A COMPESION TESTER TO CHECK FOR COMPRESION VALUES, ALL THREE SHOULD BE SOME WHAT EVEN, IF YOU DONT HAVE A TESTER PLACE YOUR THUM OVER THE PLUG HOLE RESTRICTING IT COMPLETELY KICK OVER THE MACHINE AND THE COMPRESION SHOULD BE FELT, MAYBE EVEN BLOWING YOUR THUMB OFF THE TOP OF THE CYKINDER HEAD SURFACE, REPEAT THIS FOR ALL THREE CYLINDERS IF THERE IS A SIGNIFICANT DIFFERRENCE TO THE LESSER YOU CAN THEN SUSPECT MECHANICAL FAILURE
