The bikes all good.

Cheers Mike aka speedpro for coming round and sorting it out.

It was pretty easy really. A combination of....well actually its really just me not knowing enough and panicking at sounds that werent there before. I pretty much ran out of fuel from the main line, and because it was low the fuel pump kept running as there was nothing in the carbs. Switched to reserve switched the bike off and on about 5 times to fill the carbs, fuel pump quiet, bike runs sweet. Mike checked the fuel lines and they are all clear, so i cant use the excuse of a blockage.....

Thanks for everyones input. Thanks again Mike, legend!
