Engine code FVW6673429:

FV = FLHT Electra Glide Standard

W = Twin Cam 88" Fuel Injected

6 = 2006

673429 = are the last six digits of the Electra Glide Standard VIN on the bike that engine was installed in at the factory.

Per the decoder I use, that engine number is not from an aftermarket engine. It was assigned to a fuel injected, 96" Twin Cam "A" engine. That engine came from the factory, installed in a 2009 FLTR Road Glide, with the last six digits of its VIN, "634068".

Engine Identification Number (EIN)= FS49634068

FS= FLTRI (Fuel Injected Road Glide)

4= 1584 ESPFI

9= 2009

634068= are the last six digits of the FLTR Road Glide VIN on the bike that engine was installed into at the factory.

The engine number shares numbers with the VIN, but it's an abbreviated number from the VIN.....

FYI, and anyone else reading this thread..

From 1981 on, the Harley VIN is 17 digits.... The EIN (Engine Identification Number) uses only 10 of those same digits..

The EIN uses:

Two Digit model code / One digit engine code / One digit year code / last 6 digits of the VIN...

The EIN will be located on the left side case (primary side), just below and between the cylinders.
