Fireblade over fuelling
My Stuart Taylor LocoBlade is over fuelling, I have had to put a catchment tank on the carb overflow pipe. Does anybody have any suggestions to why it
would be doing this?
Thanks

what fuel pump ya got? If you turn the ignition on but dont start the engine, the pump should click a few times as it builds up pressure and then
stop. Does it leak before the engine starts?

Not just running rich but actualy flooding the carbs?
This can be caused by too high a pump pressure, running carbs at incorrect angle, sticking float/needle valve (often due to runing with no filter and
getting crap into the carbs), or a punctured float.

The fuel pump is a standard fireblade pump. Would it be worthwhile having the carbs serviced and change the pump? I have been advised to put a GXR1000
pump on it.(don't know why).

the standard blade pump will be fine if it is working correctly. They are meant to switch off when the correct pressure is reached.
You either have too much pressure (a duff pump, it will click continually when the engine is off) or crap in your float chambers. Unscrew the covers
and have a look, taking the usual precautions about the inevitable fuel spill!

Ok thanks for the advice I'll take a look at the chambers and floats.
Cheers

I really wouldn't put a GSXR1000 pump on it. The GSXR pump is designed for injection and so operates at a significantly higher pressure than is
required for a set of carbs!
As mentioned by others, check your float heights and the condition of the float valves. Also, if the cabs have not been used for a while the floats
can stick in the 'down' position. Put some fuel in the bowls as you refit then to ensure that the floats lift and close the valves.
It's an awkward job but worthwhile....
Spin 'er off Well...
