Hi , my suzuki Bandit GSF 600 2002 plate, off road 4 years... only 2000 miles on clock...would not idle ..cutting out after 10mins when put choke in ....try to rev cuts out...drained and flushed out petrol tank and carbs.. new plugs and battery...tried no air filter...gave to motorcycle mechanic now..told him problems.. says will be carbs ,strip and clean out carbs... 2 weeks later...can get bike idling with choke..revving up to 6000rpm...but very rough so has stripped carbs several times, checked fuel filter, vacuum hoses, jets , floats, diaphrams, .. cylinder compressions checked all fine ....took bike out for run but will not give full power and cuts out...says might be need set of new carbs....so bike was off road and garaged okay ..I know water in petrol rust etc...nothing found in fuel filters..suddenly now need new carbs..he said carbs balanced everything looks fine but wont run right... when puts hand over carbs inlet bike picks up for a while then suddenly misfiring due too much fuel...feels carbs are still the issue but everything set up right and balanced ???? has also tried swapping jets around.even tried with fuel cover open any ideas, can it be electrical ??? or still fuel problem or carb problem..thanks john
