Fuel Pressure Regulator

I had two months fight with no engine idle speed. Today I've found fuel leaking from fuel pressure regulator vacuum port. So it was additionally sucked into engine throught vacuum lines and the mixture was much to rich. I've disconected this port and now bike runs like a dream again 
So I need
16740-MCF-013 FUEL PRESSURE REGULATOR
Is there any alternative ?
