Hi all,have a problem with the running of my NC24,The bike starts and runs fine, but every now and then it seems to be suffering from fuel starvation,it has had the fuel tap mod done as it has no vac pipe and the fuel will run from the tap when turned on..How would i tell if this has been done correctly.I have taken the tap appart and inside there is a rubber disc and a diaphram,should these be removed.........Thanks Steve...........

If you turn the tap on and fuel flows then it is working.

how is the tank breather? Check that...
