I have fitted CBR900 Fireblade carbs to my 1300. I started the engine and it started up straight away, but then turned it back off.

When i tried to start it again it wouldnt fire, but the carbs were spitting back fuel against the bulkhead. This seemed to be coming from some sort of jets just underneath the trumpets.

Anyone clued up with bike carbs to give me some advice??

The carbs are flooding, you need to adjust the needle valve in the bowl of each carb.
