I have a 99 Cbr 600 and im not sure what is causing this, everytime i go to take my bike out for a ride it will run just fine for a little bit but then when i really get into it, it will start to cut out and then eventually die, the same thing happens if i run it at the same rpms for a while, it's almost like it is flooding itself or just losing spark, does anyone know what this could be? Any help is very appreciated.
thanks

the same symptoms in a car usually lead to a bad ignition module, gets hot and cuts out, cools off fires up, get hot cuts out....

 

So on this bike the ignition modules are all part of the plug wires, right?

Or is it the module in the rear of the bike?

should be a separate part. On my 95 its the larger black box behind the right side rear seat panel

 

pop a few viagra in the tank. if the engine stays running for more than 4 hours, see a mechanic IMMEDIATELY.

how long do you ride before you notice a problem? is it just after warming up, or a little later? if you could be a little more descriptive, that would be helpful, because what you describe could be a lot of things. really sounds like an ignition coil - just like mine on my f150 when it died in the rain ...but doesn't the bike have 4 coils?

 

It is usually about 5-10 minutes into my ride, just about when the engine is reaching it's normal riding temp. Im gonna try getting the new module and if that doesn't work i will replace the plug wires, which have the coils in them,but i dont thinkit is that because ithink it would die completely and not correct itself after sitting for a little while.

might wanna chech the connect to the coil/wires as well.

you can see where the 4 plugs for the coils come into one plug. Check there, make sure there is no corrosion and such

 

I have step by step instructions on how to test my coils but how can i test my module? can i just use a voltage tester and how do i do it?

I had the same problem with my f2, the bike would run fine for about 5-7 min @ idle, then just die. It ended up that itwas a combo of two problems.....

1. my vent into the fuel tank had gotten clogged with some sort of crap, causing the fuel to stop flowing.

2. the fuel line from the tank to the carb was extremely worn and was pinching offat the bend just before the split.

I spent alot of timefiguring out the samesymptoms you have[:@]and thats what i came up with. a quick way to check is to run the bike until the problem occurs and the pull out the key, open the tank, close the tank and re-start the bike. if it starts and runs ok, your vent is most likely clogged. blow it out with some compressed air and you should be good to go. if thats not the case and your sure your getting fuel, check the ignitionmodule. hope this helps!
