Twin cam engine numbers decode
For future reference guys, I explained how to decipher the EIN (engine identification number) in post #33 above. It's not that hard.
KB = FLHX (Street Glide)
M = Twin Cam 103"
C = 2012
913358 = Because it starts with the number "9".... That means the engine is an off-the-shelf engine, NOT associated with a motorcycle production number... Basically the engine was sold as a crate engine from the factory.
BHY2024858, Thank you in advance
The number you posted is the EIN (Engine Identification Number). It has 10 digits. The EIN is a smaller version of the VIN, using some of the same codes as in the VIN. If you'd like to know which ones, look at my post #33 above.
Your EIN decoded:
BH = Softail FXST
Y = Twin Cam, counter balanced - Carb
2 = 2002
024858 = Last 6 digits of the VIN on the bike it was installed in at the factory
It came from a 2002 Softail FXST with an "88B" engine, otherwise known as an 88", counter balanced, Twin Cam engine. It came from the factory with a carb (Keihin CV40). The bike it was installed into at the factory will have these same numbers in its VIN, and the bike's VIN, last 6 numbers (production number), will be "024858"
Are you sure on that engine number....???
It checks out as:
KE = FLHTK model
L = 1340 EVO engine
G = 1986 or 2016 year of manufacture
642962 = the last six digits of the VIN on the bike it left the factory with.
The engine code is unmistakably a 1340 EVO engine, so the year has to be 1986.... but.... There was no "FLHTK" model in 1986...

Forget my Private message... I couldn't see the color of the cylinders in your private message... I thought they were grey. I can see now they are black... Plus, the last pic in your post above, shows it is a Twin Cooled Twin Cam engine.
Based on the pictures, the EIN, and my recent research....
I am confident that engine left the factory as a 2016 Twin Cam, High Output, Twin Cooled, 103A engine. It was shipped from the factory in an Ultra Limited with the last 6 digits of the VIN being "642962".
I was confused by the 3rd digit, which is the engine code position of the engine identification number. That is the same code used in the VIN, as the 7th digit ....
Several decoders show the "L" engine code, solely as a 1340 EVO engine....
So I have spent a little time, trying to figure out that discrepancy......
Here's what I have found out...
Several VIN decoders show several codes for the various versions of the 1690cc (103") Twin Cam engines.
None of the VIN decoders I saw, show the engine code for a "1690cc, Twin Cam, twin-cooled, HO, fuel-injected"
However, after looking up several 2016 Ultra Limiteds for sale, all with the 1690cc/103" HO twin cooled, Twin Cam engines, and then decoding their VINs, the engine code in those VINs is an "L".
When I check those VINs on the Harley SIP site, they each show an "L" in the engine code position, and define it as "L= Twin-Cooled 1690 cm3 High Output Twin Cam 103, fuel-injected"
I am now confident that the "L" engine code, in both Engine Identification Numbers and Vehicle Identification Numbers, is now a split code, like several year codes.
That "L" engine code stands for two engines; "1340 Evolution" and "Twin-Cooled 1690 cm3 High Output Twin Cam 103, fuel-injected".
Why none of the Harley VIN decoders I checked show the "L" code that way, I have no idea.... But the VINs have become a lot more confusing in recent years...
Sorry for my original confusion trying to decode your EIN (engine identification number)..
IMHO, it's still a good idea to thoroughly inspect that engine given the low cost you paid, before putting it into service.
Good luck with that engine..
