Hi guys recently afeter my cbr was up for sale it started playing tricks. I went to start the bike it started and died later on turned put the fuel pup wasent working and from tring to start it it has flooded. Cleaned burned the plugs put back on and it run like a dream. Switched it of and i went to start it in the next 20min and it hasent started and i guess it has flooded again. What could be causing this i need to get it done asap. Thnak you

My first thoughts would be to check the floats in bottom of carb and the height etc make sure they all move freely etc.

The floats have a similar effect to what you have in the top of a toilet and controls the amount of water in the basin, so it seems as if a mechanism may be faulty?

Bit of a long shot but could the jets be too large and harshly fouling the plugs?

Good luck.

You need to see if you have a spark off the plugs by removing one of the leads and turning the bike over. If there's a spark then next you need to check if fuel is getting to the carbs. So you need a bottle or jar to catch fuel in. remove the fuel pipe from the carbs and put it in the jar , turn on ignition and spin it over and see if you have fuel coming through. it could be the fuel filter is completely blocked as they are notoriously neglected, when I bought my NC29 the filter was fully blocked with rust, how it ran i don't know, maybe the same problem as yours, keep updating on problem
