K1200GT blown engine

Hi All,

I'm new to this site and maybe new to BMW ownership.
Here's whats up. I've found a guy selling a 2003 K1200GT. It looks good in the pics but has a blown engine. Before I pursue this any further I need to know what engines I can swap into this bike. e.g. K1200GT 2003-2007 except a 2005 model engine or K1200S or RS or a K1300GT etc.

Thanks for the help,
sgltrk

I do believe you are limited to the K bike range of 2002-2004. Your bike is a longitudinal layout versus K bikes in the years 2005 to 2010 which are transverse layouts.

2009 K1300 GT
1984 Kawasaki ZX750-E1 Turbo
1990 Kawasaki ZX600R
2005 R1200 RT - gone
2008 Honda CBR1000 RR - gone

As written by TF1200RT in previous post, if indeed you have a 2003 K1200GT, then it is a longitudinal 4-cylinders commonly referred as "brick-engine". These are very different than later K1200GT 2006-2008 models having a frontal "across the frame" 4-cylinders (configuration more common on motorcycle from Japan).

In your case, you can get any good used engine from either of these two:
1) K1200RS of 1997 to 2004: I would avoid the 1997-1998 because of a few issues resolved in later models. Note than Canada and Europe also got some of these in 1997 as earlier production - USA began selling these K1200RS only in 1998.

2) K1200GT of 2003-2005 (they are the same for all years except some option non related to engine)

OTHER NOTES:
Although a K1200LT engine would fit in your frame DO NOT buy this. These K1200LT have lower power output (camshafts, compression) AND they not have the middle junction for oil-cooler connection on oil-pump outlet.

On these engines, transmission and clutch are separate, so do not be surprised if an EBAY vendor sells only the engine. Depending on what you meant in you request as "...It looks good in the pics but has a blown engine", you may be able to reuse your old transmission and clutch (if there is NO oil on clutch - as it is a dry clutch by design).

See 3 attachments:
- common shape / look of these engine when outside the frame. I suppose you are shopping based on pictures from EBAY vendors...

- where to look for serial number on engine: this will confirm proper model and WEEK-YEAR of production. It is located on right lower side , just behind the oil-sight glass. In this case we are looking at a constant of "124EA" as the proper sequence for correct engine of K1200RS and K1200GT. The K1200LT have a different sequence as prefix.

Ebay? A few engines available.

A lesson on what to (or not) buy?

https://www.ebay.com/itm/98-01-Bmw-K...4098255?_ul=CA

Compression is 210-30-210-210.

This one:

https://www.ebay.com/itm/03-BMW-K-12...9139643?_ul=CA

As per the video....running (and revving) with a smashed valve cover AND oil pressure warning light ON.

That:

https://www.ebay.com/itm/1999-BMW-K1...1643452?_ul=CA

60Ks, clean and no smashed covers.Has potential but a little pricey.

That one:

https://www.ebay.com/itm/02-BMW-K120...8493430?_ul=CA

Milleage at 80K(?)but I am having a hard time reading it from the video.Bike is clean,doesn't look accidented and engine runs/responds well.Oil pressure light is out.And cheap....!

Anyway....before one does install a used engine,I'd suggest some precautionary checks.Compression first? Easy enough to mount a starter and spin it with gauge attached.

Thanks for the list. I am sure he will be glad you did the hard work for him.

I would probably avoid the last one in your list (quoted above) as the vendor does not have "good enough" EBAY feedback record as far as I am concerned. I read the individual comments on the negative feedback transactions and get a feel for the vendor...

Besides having many good clear pictures , mileage , compression in this specific case , I ALWAYS look at vendor feedback stats AND any negative comments before buying anything used on EBAY. This has served me well in 95% cases.

Just a thought, if the engine is blown, chances are the rest of the bike wasn't cared for properly, either. Unless you have a specific desire for that particular bike, I would suggest finding a BMW in good running order. There are MANY out there, that had owners who took care of their vehicle. Spend a little more money and save yourself mountains of headaches.

I go with BBsteed's comment to keep looking. I own a 2003 K1200GT with 27k miles. Already in the financial hole from resale price values.

Many GT's and sister RS of 2003 are in the $2500-3500 price range.

An example is this in Chicago area:
https://chicago.craigslist.org/nch/m...980307498.html

https://chicago.craigslist.org/wcl/m...986599970.html

My bike is near perfect regarding maintenance needs. New tires and fluids changed was about $2000 after all done. Much of it I did myself. The K1200GT is a great ride.

Say you get your bike for $500. Add $2000 for getting the bike up to stuff beyond the engine you are in the range of a working bike. Oh add the price of the blown engine that pushes you into a financial hole.

Great info Sailor. Very much appreciated. Particularly the tip on avoiding '97-'98 and the pics as well.
