TENDS TO SMOOTH OUT AT 25 RPM'S. PROBLEM FIRST STARTED AFTER CHANGING FRONT MOUNT AND "Y" PIPE. DEALER HAS OVER 8 HOURS IN BIKE AND CAN'T RESOLVE AS OUT OF WARRANTY. UNIT HAS 28,000 MILES. INTAKE GASKETS REPLACED, HAS STAGE 1 AND REMAPPED. EVERYTHING IS IN LINE? DON'T KNOW HOW LONG "Y" PIPE WAS SPLIT BEFORE REPLACEMENT, I INITIALLY INSTALLED MOUNT INCORRECTLY, BUT SINCE RESOLVED. ANY THOUGHTS? COULD THE FLYWHEEL BECOME OUT OF BALANCE? VALVE WARPPED? ALL OTHER MOUNTING HAS BEEN INSPECTED AND MOUNT CHANGED. INJECTORS WERE UPGRADED WHEN NEWER. HELP SUDDENLY WENT FROM SMOOTH TO RIGID MOUNT. THANKS ....AL

I have the same problem with my Roadking except it wasnt dropped. I did a full alignment of rear tire to engine, aligned the rear tire to front tire, aligned the engine and replaced the front motor mount. Nobody seems to have an answer, that I've talked to anyway. If you find a cure let me know, If I find one I'll let you know.

Hi .... This may sound daft but have you recently changed or had the exhaust off ? Have a look at the silencer/muffler rear mounts, difficult to explain but they should be in a 'neutral' position, not fully pushed in. Maybe the vibes are coming straight along the pipes from the engine and through the footpegs.
Let me know how you get on.

I would take it to another dealer. You don't have to go back to that dealer for warranty work. If your getting codes like that I would almost go after who tuned it. Make sure that it's tuned right. If it doesn't have a super tuner on it that could be a problem too.

One more thing to try...loosen the gas cap when it starts misbehaving. If the tank is losing its vent, then it can act that way.

Harleys sure do some shaking. I would guess it has an issue with an engine mount either loose or worn out. I would try another dealer if one is near you.
