Grum, thanks for the answer, my experience with engines and mechanical items has been lifelong, rode motorcycles for 40 years, ran a mc shop for 5 years, bsa norton triumph, 25 year aircraft mechanic, the engine on my bike definetly acts lean, never the less, this winter i will strip the bike and perform all the mods i can, electrical etc. i will also go through the fuel system, fuel inj. filter, regulator, plugs.. i have set the throttle cable freeplay to min, my bike is a 2003, with 5400 miles, has been well taken care of, my idle is 1300, at low throttle settings you can feel the bike is hunting so to speak, i think i will also replace all the vacuum lines, do you have any info on remapping ? is that the only way to enrichen the system at low rpm? all help is appreciated....bog
