GS1000 ignition Timing
Is it me, or are the instructions in the service manual confusing on doing this procedure.Tags: None

I am a little confused at where I set the gap. For instance the first step says to set the gap for the nos 1&4 points. When? When the mark is at F 1~4? OK, I set the gap, But then the next step says to move the plate CC until the points just start to open. Well they were already open.
And what is the difference between TDC and BTDC?Last edited by Guest; 07-07-2009, 04:35 PM.

I'm doing the same thing on my 78 1000 right now. I believe the manual says to start with the l/h side points first (1&4) rotate until they are at the widest gap and set it to .035mm. then rotate the engine again with the test light or meter connected and find where they just open at. The fixed timing mark should now line up with the mark just to the left of the F 1-4. If not adjust by moving (rotate) the whole plate with the screws at 12, 4, & 8 oclock. Same deal with 2&3 except to adjust point opening position you move the half plate on the r/h side of the assembly and you use the line to the left of F 2-3. Loosen the screws just enough to move the plates, always rotate clockwise, and check it a few times. Hope this makes sense.

Thanks a lot, makes sense now!

I set them up correctly, but one does not spark at all. They are worn, time for some new ones. And yet again I have to order more parts, and wait for them to come in.But, in the higher rev range, it did miss some every now and again on 2&3, so I suspect, that this set of breaker points was intermittent. So with new points, hopefully she will not hiccup at all.
