Default Running Rough

Hi Everyone,
I am riding riding a 2007 FXD. The last couple of years I have noticed some pretty ugly vibration at lower rpms. Along with this is some pretty messy engine/exhaust sound. One if the things I have noted is that when I come to a stop light the bike doesn't settle into that rhythmic idle that sounds so good. The engine and exhaust sounds random. I took the bike in last year and the mechanic treated the vibration by changing the motor mount and the rough idle was attributed to a bad seal. Neither if these seemed to do anything to treat the overall roughness of the motor.

If anyone has any ideas I would appreciate to hear them.

Cheers,
Chris

Have you changed out the plugs, and cleaned or changed the air filter?. Is your gas fresh?. Alot of little things can make a bike run crappy, look at those first.,,

I have new plugs, wires, filter. Gas is a non factor. I was going to run some sea foam through there.

It's crazy the vibration will shake the **** out of my fairing...

As it's an '07, did you go to a dealer tech or an indy? Maybe try another mechanic.

Indy. He's pretty well regarded. You're right though, time for a second opinion.

Have been running a top tier gas in it? For years I ran the gas from a reputable station here in town, then after some research starting use a "Top Tier" gas. The bikes started running better, I'm thinking the injectors were carboned up and the better gas cleaned them up real good. I'd run that Seafoam for a few tanks and see what the engine does. Was 07 the year for the injector tech bulletin?

Thanks for that. This will be my 4th season with the bike and I have never put anything but premium fuel in it.

I was looking at your location and I was suggesting "Top Tier" as in U.S. standards. That would be Shell, BP, Chevron. Google Top Tier in Canada and maybe they will list the T/T gas. In the states T/T has has extra detergents in the gas and local gas stations will have minimum amounts of detergents as required by law. If you can't find a T/T gas use Chevron Techron at recommended dosage to help keep the injectors clean. Good luck.
