Hi.
Swapping timing chain on a -07 K1200GT after 80kkm.
Strait forward work but by the lower ( crankshaft ) chain wheel having a "challange" loosening the bolt.
Can the bolt be left winded ( turning counter clockwise ) to loosen it ?
can only notice a blank surface on the top of the teeth of the lower chain wheel. When is it better to replace that too.
PS: replacing chain, guides and upper chain wheel. Having also a new lower chain wheel on the workbench.

Do you have this part of the service manual?
Thanks having the DVD with interactive manual.
Seems that I have a version of the engine.crankshaft with integrated kamshaft wheel as there are to bult,distance holding it and it can be fasten by shrink bandage on the crankshaft. Even though it seems prepered for a detachable camshaft wheel as it has a winded hole in the crankshaft.

Had a look at realoem.com and it seems that the sprocket are shrinkt on the crankshaft on up to 11.2006 then on redesign crankshaft / sprocket to removable sprocket locked with a dowel pin, countersunk screw as in the DVD workshop manual.
A Q. can it be that the crankshaft are from before 11.2006 designed with for aftermounting of a dowel pin and a.s.o.?

A second thought.
Any reports from a engine crash due to moved lower sprocket coursing valves hitting the piston from a pre 12.2006 bike?

Impression;
Strait forward to remove faring ( lower panels. ( 3 pcs ), radiator with fan and cover, secondary air tubes and ignition coils.
PS: better to remove also 1 cyl spark plug.
Remove clutch cover and valve cover.
Turn the crankshaft 17 mm socket until the marks on the upper sprocket are in line with the valve cover surface.
Remove one of the E8 torx bolt on the upper sprocket. Turn the crankshaft one turn until the marks are in level again.
Look the engine by installing the special tool instead on the transducer in front of the engine. remove the other E8 torx bolt.
Remove to upper sprocket and the timing chain. Remove the tensioner ( consist of to parts ).
Remove the guiding rails.
On past nov.06 manufactured engines replace the lower sprocket.
Insert the new chain and new guiding rails. and the guide over the lower sprocket.
Put the upper sprocket in place ( adjust it until the marks are roughly in level )
Next step insert a 5.0 mm drill in the hole close the lower sprocket.
Remove the special tool in front of the engine ( and install the transducer agin ) and rock the crankshaft a few degr clock / counter clockwise until the upper sprocket falls in position than move the crankshaft until the drill snaps into a a hole in the crankshaft.
Check that the marks are in near to or on level again. Look the upper sprocket with one E8 torx bolt.
Install the tensioner and turn gently the crankshaft until the maks are in level again and install the other E8 torx bolt.
Check the timing with a long rod install in the hole of the 1'st cyl spark plug.
Turn the crankshaft until you feel that the piston are in upper TD and simultaneously push the drill inside again until it snapps into position. ( should be appr at the same time ). Check that the marks are in level.
Next install covers, 1'st cyl spark plug, all coils and connect them, secondary air tube.
Cooler with tubes.
To refill the cooler and engine, first fill the cooler on the right side ( put the cap back ), then fill the expansion can with oen cap.
On the right side top of the engine you will find a breathing plug on the water pump. Connect a vacum pump to it and suck out air from the heating. Pls. keep the level in the expansion can while doing this. When only a few bubbles appears in the tube to the vacum pump you have filled the system with appr. 95 % of cooling liquid.
Next step close the expansion can cap. Run the engine half warm and open both breathing plugs near the the wather pump ( the second are on the tube to radiator ). Close them when no more air comes out.
Let the engine cool down ( letting the self breathing work ) . Run the engine full warm and breath it again.
Install panniers, dress your selves and enjoy a ride.

Tiberg are you sure about this. I think you have it the wrong way round. Bikes after 2006 have a pressed on sprocket
Below is the information from Motorworks re the camchain kit
A kit comprising the timing chain, the crank and camshaft sprockets.
Please note: this kit applies only to bikes produced before 11/2006.
Bikes produced from 11/2006 use the following;
  • 11317707207 Timing chain
  • 11317701209 Camshaft sprocket
There is no separate crankshaft sprocket available for bikes produced after 11/2006.

Many Thanks Capt Howdy.
You are right I miss read the realoem.com pages.
Helped solving a puzzle on my -07 bike with crank shaft sprocket integrated with the crank, it's has a 2007 engine.
Will correct my info to the swedish BMW MC club ( appr 6000 members ).
PS it's possible to check what version of crank sprocket by inspect trough the Screw plug, Torx 11147704598 on the clutch cover before ordering parts.

BTW. cranked the engine and it spins like a cat at idle and roar like a angry tiger when touching the gas ;-)
