I am trying to find the sweet spot idle on my new 15-570.Took the rubber boot off the accelerator cable and if I turn the cable too far out the engine races at idle.If i turn it in, the motor wants to stop on sharp turns or after full throttle.I am now truing to set my idle with it in gear and as I turn the cable, the bike will start to move forward,so I back it down then it runs real low and sounds like it is chocking out.How do you set yours.
