that low end bog and cutting out is normal in the low end... the boysesen accelerator pump got rid of it for me, but people on here say that supposedly going with a smaller "leak jet" (not sure which one that is) will take care of it...
HMF's jetting reccomendations are pretty close... what is your current jetting, temp, and altitude?
