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,
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)
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.
