If coils are OK I will buy a DYNA S pick up/rotor and later on buy the coils to match, ideally I would buy the DYNA 2000 system to junk the mech advance unit but it's too expensive.

It's all Greek to me!
Having ignition problems but cannot afford to get full electronic system yet (POST XMAS POVERTY), Have tested coils for resistance and figures are 3.8 & 4.2 ohms on the primary circuits, 14,500 & 14,400 ohms on the secondary circuits. manual states they should be about 4 ohms and about 13,500 ohms repectively. Can anyone tell me if my coils are OK with the resistances I have measured, not being electrically minded I don't know if the variations form the manual figures are excessive or not.

Rich,
Problems at present are that I'm getting no sparks on 2&3 cylinders, swapped wires over and problem transferred to 1&4. Excessive arcing at points on 1&4 and still no spark at plugs on 2&3 (after reconnecting wires as they should be). Points look worn/pitted so I reckon that the condensors are duff/on their way out hence excessive arcing at points. I wanted to eliminate the coils as another cause of no sparks and it seems from Jerrys and your replies that the coils are OK.
I think I will try a Dyna S pick up/rotor running with stock coils until I can afford Dyna coils.
Another issue is that although my bike is a Z1B the advance mechanism is off a Z1, I'm told that the advancer on the Z1B (coupled with modified carbs) gave smoother idle so I wonder if it is worth changing this as well? The rotor on the Dyna S is different for the Z1 so I need to get this resolved before ordering the Dyna kit.
The problem now is that if I need a new advance mechanism the cost will be almost as much as a full Dyna 2000 kit with coils included from Jeff @Z1 Ent which will be the mutts nuts in terms of efficiency/performance- decisions ,decisions!!!!!!
