The Neck Stem Nut, center of bottom triple tree, may be too tight.I had a 07 Mastiff, carburetor, was hreat bike. Put 42000 on it. Had back surgery, sold it. But it never vibrated this bad or steer this stiff.
So now bought 08 fuel injected, which seams to idle high.
I appreciate all this info
On the left side of your throttle body, is the TPS, Throttle Position Sensor.
There are two screws, loosen them slightly and move the TPS Clockwise and Counter Clockwise , just a hair is all it takes, to adjust the idle.
The correct way is to download the ProTune software from S&S and get connected to your ECM and adjust it by the gauge page.
Read the Manual for ProTune as it is too much for this forum.
