my 06 roadking shakes alittle more than i'm used 2 its completely stock.this is only at idle increase the rpm just alittle 100 or so and it feels just fine no shakes at all. i'm thinking TFI so i can increase the idle rpm 75-100 dads RK has a zippers fuel manager on it and it idles great (05 model) his engine seems to run alittle cooler than mine also
