Title: K100RT timing help
Post by: Puccini on July 06, 2013, 05:11:51 PM
I have a digital timing light with an advance setting.
From what I understand from things I have read, all I need to do is remove the timing cover, put the timing lead from the timing light on plug #1, set the advance on the timing light to read 6 degrees BTDC and
look for the proper match on the timing marks .

Is that correct?
It's the first time I am trying to check the timing on my 85 K100RT

I can't finds any info on doing it this way. All the manuals call for using some BMW tools.

Any help out there?

Try the search function with the word timing.  I saw write up either here or at IBMWR.org

All the things I found about timing are way too technical.
Hard to understand.

What I think I have to do is just remove the timing cover, warm the bike up, hook up the digital advance strobe light to the #1 plug wire, set the digital advance on the strobe to 6 deg. BTDC and see if the marks line up correctly.

Is that right?

Is there some other degree setting that is desirable other than 6 deg BTDC?

The timing light may be configured for a different engine setup. You are pulling off of one cylinder, with a wasted spark system. To the timing gun, it appears as a 2 cylinder engine with a distributor. Most timing guns are setup to do 4, 6, and 8 cylinders. Set it to 4, and half the desired advance.

OK, so if I decide to do the static timing procedure using the TDC of Cyl #1, how do I turn the engine to get TDC?
I'm used to the flat twins having the allen wrench to turn the engine.

Also where can I get an affordable TDC indicator that fits the K100?
Does static timing require a hot engine?
