hi i have a 98 f3

the fuel runs in fine the pump is good the filter is good and the spark is good and from what i can see the carbs are clean

when i try to start it
it doesnt sound like it is turning over and the floods
if i wait to long it spools up in the exhaust and fires out like a back fire

whats going on help please?

 

What condition is the battery in? make sure its at peak charge. Just a thought also, but you don't have the kill switch on do you? On my bike, starting from a cold motor, full choke, petrol turned off & I don't touch the throttle. If the motor's flooded, then turning the petrol on isn't going to help.
When you try to start a flooded motor, you hold the throttle open & keep it there, you don't pump the throttle. They can be sensitive buggers to start & I have seen a lot of people (not just on CBR's) put the keys in the ignition, twist the throttle a couple of times & then hit the starter, Ok if the bike is a 66 model Norton, but on modern bikes with carb's it often floods the motor (& on fuel injected bikes a waste of time)

 

the battery is always fresh charge the switch is at run
and it doesn't start flooded

i have the choke open and i dont throttle it at all so beats me

 

change the plugs, maybe bad coils
