I'll try the sea foam. Could be the power commander, and yes it is a canned map. No one around here does dyno-tune, but the local hd shop is getting the stuff to do it. My problems started before that was installed though but the misfire is new.

These are all cheap possible fixes. As far as the vies, what was the last thing installed before the vibration started?

IMO lugging would be different on different bikes. the Andrews 26's pulls our bike fine at 2k rpm's, but I don't do a full throttle accell in 4th, 5th or 6th

Whereas some builds wouldn't let U ride that low of rpms.

According to my print out of Nighriders Speed vs rpms, our 07 at 50mph in 5th is right at 2300 rpms.

In 4 yrs I've ridden quite a bit (mostly 2-up)in 5th at 50-55mph. I will add the cams do help. Wouldn't call it lugging at all.

The stealer says that couldn't possibly be causing the vibration that they say I'm not even having, but I told them they had better start taking things apart until they find something.

Any bets on what my bill is going to be if they don't find a warranty issue?

they are gonna check out all clutch components, compensator, crank...

My FatBoy developed a vibration between 2,200-2,800 RPM's so bad it would shake the tank. I checked mounts, ignition, anything I could think of before tearing it down and finding my counter balance gear had shifted on the crank. Hope you find your issue soon.

Sounds like Secondary Ignition System to me. The Secondary Ignition System includes: The Ignition Coil, Spark Plug Wires, and the Spark Plugs. The toughest time for these parts is when the engine is under a part throttle acceleration. With an engine oscilloscope it's fairly easy to figure out which is which pretty quickly. Without a 'Scope as inexpensive as the parts are, I'd try replacing the following parts in the following order (yea, it's called parts changing and it isn't a real elegant way to do this but . . . ) 1.) Spark Pugs, 2,) Spark Plug Wires, 3.) Ignition Coil. Also, there is a reasonable chance that it could be something else: A bad ground somewheere in the ignition and/or computer system, a failing Crankshaft Position Sensor, a bit of water in the fuel, etc. I can tell you that if it wasn't happening before with the old Map, changing the Map isn't going to fix this.

Why a Dealership would NOT have an engine oscilloscope if they are in the business of repairing engines entirely escapes me . . . but then again I forget myself . . . we're talking about a Harley Dealership aren't we . . .
