Dyna s

[Steve R]

Has any one else had problems setting timing up with Dyna S ignition. I am using the maximum amount of adjustment on each of the two sender units and I have 1 and 4 coil slightly advanced and 2 and 3 coil slightly retarded .
There just isnt enough adjustment to get them both right .

I am timing to the lines 1/2 inch to the right of 1/4 and 2/3 static with sender at full advance and dynamic at 2500 revs. Getting same result with both.
At moment have set it up with both equally wrong and it is running ok but I really ought to be able to get it spot on.
Any one else had this problem.

Steve, I have installed these Dyna-S units without any drama. However, I read recently on the KZforum where a guy has the same problem. He has found that he may have the wrong magnetic rotor, one that is 10 degrees advanced. Like many posts, you have to prompt the initiator, to find out if a replacement worked.
A link to the post is:

I[/url] hope this helps, I am always reluctant to file slots in the plate. No doubt you are aware there is a small amount of movement on the individual pick-ups.

Another area that could be investigated is the advance mechanism not returning consistently, or the wrong mechanism having different "T" position.

I take it your bike is a Z1 series and you have a Dyna-S (DS2-1).

Thanks for that Garn, yes its a Z1a and a dyna s ds2-1
I e mailed jeff at z1 enterprises and he has suggested the same as the guy on that forum , there is a different pick up. I am going to look at mine to identify it this morning.
filing slots in the base plate wont help I am in the middle of them any way its adjustment on the modules that I am running out of.
I stripped and cleaned the advance mechanism and it was fine. Also when timing statically youi are manually holding in full advance mode so that would rule out the advance mechanism malfunctioning.

Steve, I'm still watching that posting I talked about previously, where the guy possibility had an incorrect rotor. However another member of that forum who had the same symtoms that you were experiecing (looked like he needed to widen the slots), found an answer.
He simply, checked it out with a timing light at approx 1000 rpm set on "F", Then adjusted the 2-3 side to read the same, by slight adjustment with pick up, then checked them at high revs to see the advance mechanism working.
Here's a copy of his posting:

Re:DYNA "S" SET UP PROBLEMS - 2006/06/21 23:24
#1 no I did not file the slots any.
#2 I had the thing timed fairly close using the instructions from DYNA, but could not get right on, so I used a timing light to set it bang on..With the bike running at idle(approx 1000 rpm) I set the timing using the "F" mark for 1/4 and then 2/3.. Then I would rev engine over 2500 rpm and made sure the advanced timing marks lined up.. Thats it..

While trying to set the timing statically using a 12 volt bulb, and using the advanced timing marks, it seems like you run out of adjustment, just get it close and start it up, the adjustments are much finer then...

Thanks to 1045 (KZ forum).

Thanks Garn,
The guy in that first posting is having exactly the same problem as me and I am waiting with much interest to see how he gets on . I have tried using a timing light at 2500 rpm and static light and its just not possible to get them spot on. There is plenty of adjustment on the back plate not enough adjustment between pick ups.
I have e mailed Jeff at Z1 and dynatec, just awaiting some answers.

Lads, you can't beat a proper dial gauge & timing disc. Take plugs out and get TDC. Fit the timing (degree) disc & check advance degrees agains bikes markings. This will ensure all is tickerty boo! Then, as already mentioned, start her up (don't rev the tits off it tho'!) and check with strobe, idle & full advance! The advance is obviously the most critical one to get right. Keep an ear on the engine for the first ride to check she ain't pinking. If she is you'll have to back her off a bit (reduce advance a few degrees) to avoid damaged pistons/over heating due to detonation. My Z1000 (1075cc) has Dyna S and I've had to back her off 5 degs from factory markings coz she pinked under load. Even with Super Unleaded fuel, but this is probably due to slightly increased compression too! Check Advance unit springs, if original, probably knackered anyway!

Pigford,
My problem is that its not possible to set the ignition modules so that they fire 180 degrees apart.
The timing marks, advance etc is all irrelavent cos whatever marks I use the only way of getting it to fire 180 degrees apart is to drop both modules so low that the top screw is not holding them on!
I have discussed this with Jeff and he is sending me another unit which I am hoping to get this week as I am supposed to be having it Dynoed on tuesday!

Steve any word re-replacement of dyna-S pick-ups?... What's the status?

Hi Garn,
I was just about to post an up date, I got the replacement Ignition unit from Jeff on monday he must have put it straight in the post the minute after I had finished speaking to him, I am very impressed with how helpfull Jeff has been and how quick he got a replacement to me.

Any way I got round to fitting it yesterday, I Still had to move both the modules down as far as they would go, but this time that was enough to get both timing marks bang on so problem solved!
I have not ridden it yet, however I am getting it Dynoed next thursday to set the carbs up so I will get them to double check the timing to make sure I have not been doing any thing stupid!

I had this trouble with my ST. The only way I could get it right was to use a timing light. Strange how some are no problem and others cause grief.
