Re: timing

Looking at a GS-911 real time log I took a while back at steady state idle (1000 rpm, engine temp 27C) it was showing ignition angle between 9.5 to 11.97 degrees with an ignition dwell of 23. Revs up at 4050 RPM it showed ignition angle 42.94 with ignition dwell of 77.33 (but the engine was only at a temp of 55C).

Re: timing

Clymer manual says that timing must be set by using the MoDi-TeC unit. Not sure if a GS911 can do this or not.

In this particular case, I would say the CLYMER manual is incomplete - the BMW shop manual gives a few more hints - but none of these 2 manuals gives you all the options:
1) You need a dial-gauge into plug-hole of cylinder 1 (front) to set the static timing of hall-effect-sensor plate. The Motronic will do the rest for advance when engine is running based on various sensors data.

2) The static timing is 6 deg BTDC and this corresponds to 0.24mm (0.0094 inch) of piston travel BTDC (hence need for a precise dial gauge attachment device). Normal engine rotation is counter-clockwise view from front of bike to find point BTDC.

3) To rotate HALL-effect-sensor plate at correct position (to trigger), you either need: (A) Dealers computer, (B) a GS911 , (C) reach into the relay-electrical box to get the connector of Hall-effect-sensor

The menu in GS911 are pretty much self-explanatory, but if you need a few hints and want to use the method in (C) above, then you need to read a technical document that was done by a few of our members here. Document is in menu of this web site ("tools" ... "technical"). A direct link to correct file below - you just need to click on image to start download of this MsWord document:
http://www.bmwlt.com/files/displayim..._display_media


P.S.: All models and years of the K1200 "brick-engine" (K1200RS/GT or K1200LT have the same static timing value stated above. However, when these various engines are running, Motronic is coded differently for each and you would see the timing advance to vary a bit (in real-time values or in real-time log). This is expected as they have either: different camshafts, different compression ratio, different throttles-bodies...

That was my 2005 LT. But I +1 on what Sailor said on setting the timing. That is the only way to do as there are no timing marks for a timing light.

Looks like a real good reason to mark it if you ever have to remove the plate.

George, there is a possibility you can use a digital caliper as most of those have a depth gauge out the bottom. Not sure I would trust a manual caliper to read .24mm by eyeball with any accuracy.

I see your dilemma. Good luck getting it set properly and with the new motor.
