Hello and welcome to FixYa!
Yes there can be expired fuel on the bowl. You may want to clean it thoroughly as a first course of action. Please do check and replace the spark plugs and plug wires too for they can be worn out which may cause irregularities on current supply.
If the problem still persists, please do check the vacuum lines too. If you have disconnected or worn out vacuum hoses you'll have vacuum leakage. If that's the case, please have it replaced to resolve the issue. Wish you all the best on this and hope to get your bike back to it's normal running operation.
Hope this helps and thank you for using FixYa! Have a good one!
03 gsxr 750 died at high rpm in 2 wont start
Hello make sure you have gas in the tank you may be low.
try this unless you already have. turn you fuel valve to primary and try again to star the bike.
the other problem that happens is the fuel **** vacuum diaphragm may have a gone bad that is located in the body of the fuel petcock to check it unhook one of the fuel lines and replace it with a length of hose to a container to catch ant fuel then crank the engine it should flow is it does not remove the petcock and get a replacement diaphragm sizuki doe's not have it available but K & L has them available. hope this helps
Carburator is to rich
by adjusting the air mixture screws turning them out by quaurter turn at a time on the carbs but before you do that check to make sure your air filter isnt clogged because that can cause the same problem as well as poor fuel consumption
hope this helps
My suzuki katana some body move the screws in the carburators
hi,this might help,it is very difficult to get the adjustments right without a set of carb balance gauges,the adjustments are very small and critical to the running of the bike,borrow or buy a set of gauges,hook up the gauges,balance the left two cylinders together so they are both running exactly the same,then do the two right cylinders and get them both running the same,then match the two sets together using the balance screw between no2 and no3 cylinders,a general rule of thumb to get a startng point is to wind the mixture screws in untill they stop,then back them out about 1.5 turns,do the same to all four screws before you start trying to balance the carbs,make sure the bike is sitting vertical or on the centre stand because if it is not it will effect the balance of the carbs and also make sure you have a good airflow over the front of the motor for cooling as it will take half to three quarter of an hour to get the balance right...most bikes need the carbs rebalanced on a regular basis because when the parts of the carbs start to wear the balance will change,a good set of carb balance gauges is a worthwhile investment...hope this helps
When gas is pulled engine spits and sputters
hi mate adjust the needle in the carb on the piston there is a little clip and there are 5 slots or less move it to the correct one in the manual 3 slot from top etc also adjust the mixture screw on the carb it will say the amount of turns in the manual e.g 2 1/2 turns out so screw it right in till its tight and undo it so many times
Suzuki gsx750f not sparking
Good possibility, You can check the out put voltage of the pickup coil. This has to be done with a "peak reading volt meter". There are some commercially available adaptors to insert in a standard volt meter for this check. With adapter installed, meter set to DC volts the reading across the leads from the pick up coil should be 3-7 volts at cranking speed. You should also confirm that you have battery voltage with the key & engine stop switch on at the cdi box as well as a good ground. I believe on a Suzuki this will be the orange/ white for battery voltage and the black will need to have contininity to ground. Also the orange/white at each coil should have battery voltage with key and engine stop switch on.
Misfire sound
compresion tsest could be a slightly bent valve, or valve too tight, inlet side.
