carb problems ????

I've just got my car going and been trying to fix this problem today,When I open the throttle gently the engine revs without to much off a miss/stutter but when I floor the throttle the engine starts to miss quite badly,It does the same when underload and when ticking over.The engine is from a GPZ1000 RX and the carbs a kehien 36mm.

Any advice would be appreciated as I'm toiling now !!!!!

I don't know anything about bike carbs but if they were webbers i would say check the size of your accelerator jets or if it was working check that they are functioning properly.

do you know that your engine timing is correct? Best to check this first

Timing is same as when stripped from bike.
When the engine came out of the bike it was running perfect,I stripped it out.
The engine sat over winter and this is the first of me getting it going.The only thing I have done is change plugs,oil and filter.

Most likely a fuelling problem are you pumping the fuel to the carbs could be to much or not enough pressure.

The fuel is pumped using orginal bike pump,I think I will give the plugs a try tomorrow

I'd personally drain all the old fuel out and change the fuel filter. After that, a quick disassembly of the carbs will show if there is a clog. To me, though, it sounds like the fuel filter is clogged.
