I have a 1995 cbr 600 f3. I stored it last fall and shut the gas off. Now when I start it and turn the gas on, gas pours out of a over flow line and doesn t quit unless I turn off the gas and bike the keeps running.

Carburettors probably in need of a cleanup inspection/overhaul. Also a good opportunity to fit new plugs if it has old ones...

My bike has fallen over many times in the driveway lol but always starts after. Was the bike stored for six months? The gas may be bad. I would drain the tank and try fresh fuel. Also check your fuel line. IT May be pinched off from the fall restricting fuel flow. Also check the fuel filter, may be clogged from old gas too.

Easiest way to find out is fill some petrol into tank and see where it drip out from. Good enough help?

Change the spark-plug.If don`t work check the induction coil.

yOU MAY HAVE A VACUUM LEAK AT THE MOTOR

wow, 7 years without use! try to check if the fuel pump motor is still working... also check the fuel lines if its clogged.. I hope you get your bike up and running again... feel that adrenaline rush when going 100+mph.. hehehe.. have a good one bro...

I have a 1995 cbr 600 f3. The main fuse is found by following the positive terminal wire to a relay. It is a box with a red fuse cap on top, in a rubber casing right behind the battery.

there isn't a 99 cbr 600 f3. the f3 ran from 95 thru 98

I have a 1996 cbr 600 f3 and when I first bought it used it would not turn over for the life of it. It turned out that a major problem was the spark plugs needing to be replaced. Thats the first thing to do. Next clean out those carbs with some good carb cleaner.
