Title: K1100LT Carcass Research
Post by: dbamberger on October 15, 2023, 06:03:45 PM
Hey folks. 

I recently brought home some parts which I was told was a k1100.  I've done a VIN decode on it and the frame, at least, comes back as a 1996 K1100.  This was someone's project bike so most things are gone.  It does have the engine/trans/swingarm/final drive.  I'm wondering if there are ways I can identify what they are.  There's a casting on the engine block on the right side.  The number cast there is 1461479. Would that tie an engine to a VIN? Would it identify the engine at least?  Are there similar castings for trans and/or swingarm that are still covered in grime? 

Thanks in advance.

What are you wanting to know about them.

Really basic stuff like:

* Is this motor really from a K1100?
* Is it the motor that originally came with the bike? 

After that I haven't really thought about.

It's kind of late in the game to be identifying what you got; it must have been a bargain. Be happy you don't live in the EU or UK or elsewhere that having the original engine might matter.  :laughing4-giggles: Does it matter where you live?  177381 If it has a cam cover and underside mounts on the transmission as indicated in the images below, it's likely to be a K1100. The engine number is stamped on the sump as shown below; the VIN plate on the frame will identify the original unit.

Thanks!

It was definitely a bargain(came with an Ohlins shock which I'm excited about) but a bit of "trust but verify" never hurt.  I'll go have a looksee in the areas you suggest. 

Regards.

This is your engine number: 114EA  11 96 2012  The following extract is the explanation about it from BMBikes (http://www.bmbikes.co.uk/enginechassis.htm).

A K Series engine number will look something like this: 104EA 1799 2032- the first two digits refer to the engine capacity (1000cc); the third digit shows the number of cylinders; EA is some reference to a Federal Emission Code; sixth & seventh digits are the production week number (week 17); eighth & ninth digits are the year of manufacture (1999); the final four digits are the production number on that weeks production.
