Bike breakdown... help

I had the afternoon off from work (well finished early at midday) so I thought it would be nice as it was slightly dry to jump on the bike head out to the country side and stop at a pub and grab a late lunch, such a lovely plan.


Got 1 mile away from my house before the bike (Honda CBR600 fx '99 carb model) bogged down a stupid amount, as in, open the throttle up slightly and it just sounds like it is coughing spluttering and starving itself. Get just passed a round-a-bout when it cuts out and won't start, turn the engine over and it catches and get about another 500 m before the same. It couldn't keep its rev's up and stalled itself between gear changes. So call a truck to pick me up but half hour passes and I get the engine to start again so I cancel the truck and 2 miles further on the same thing happens... 4 hours out and 10 mins of riding. 

Any clue as to what might cause it? There is no blown fuse, battery is fine, enough petrol (full tank last saturday, got half left) no vacum in tank. Increasing the idle speed didn't help or using the choke.

:upset:

Cheers,

aj

Sounds

like one of the diaphragms in one of the carbs are split!


Take off the tops of the carbs & twist the throttle open & closed slowly while looking at the rubber diaphragms, they normally split where there attached to the slider, only takes a very small split so look carefully.

Jaffa hit the nail on't head, had a similar prob with my CBR600FW, it's the fuel pump, whilst your bike was stranded at the side of the road gravity allowed a small amount of fuel to trickle past the pump which allowed the brief re-start. Testing it's simple, just connect it direct to the battery (make sure you don't make any sparks!!:ph43r:) if it runs I'm wrong & it then has to be a blockage in't fuel line/filter or breather 

Good luck with it, hope you sort it quickly:smile
