Need confirmation that timing is set wrong on my 1976 KZ900

Hi Rolf, regardless of where you set the timing the "dwell" (coil recharge period) will be the same amount of crank rotation so no, it shouldn't give a problem with the coils


Thanks  for explaining Wookie58.  I still dont understand why when setting the timing exactly at the advance mark (and the test bulb goes on). then the testbulb lights up 2-3mm after the F mark.
And when setting the timing so it is 2-3mm before advance mark the test bulb goes on exactly at the F mark. Must be something wrong with the dyna-s ?? Or is is maybe the something wrong with the distance the picupcoils is sitting on the timingplate to the rotor making them send signal for a too long period? or maybe this duna-s that was fitted to the bike before i bought it not was for kawasaki?

Well i will continue to run in the engine and see if it everything is okay and then if not  maybe buy a new dyna-s plate   or     start to try to install that boyer bransden kit that has coils included.  or     start making that coil relay mod

If it is sparking the dyna is not broken.
When setting the timing at full advance you are holding the rotor fully clockwise with your fingers as you rotate the crank aren't you ?.
That is the only way it can be done unless you use a strobe light..


Yes that is how i do it .   I have bought a strobelight and planning to take a ride and check it with that .I have not used the strobelight before.

I bought one of those cheap Dyna copies and the rotor magnet was 2* off so it was impossible to get it on time. I bought the Dyna rotor and now it's spot on. Dyna said the triggers are junk but they work for now. I'll install my Dyna plate to see if it still works. I'm thinking that may be your problem too.
