TOPIC:

I have an 2119-1020 CDI on my 1981 KZ750H. I have a 2119-1050 on the shelf from a 1982 GPZ750. Are the advance curves much different. Would the GPZ igniter be an upgrade?

I tried searching on the web but found little information on this.

The ignitor is not going to have anything to do with the advance curves since those bikes have mechanical advancers.

This pic is of the 82 GPz750 ignition, if there is any difference in advance it will be in the timing advancer (the round thing at lower left).

I thought the 82 GPZ 750 had electronic advance, but I'm not positive. I could've sworn my friend's gpz750 was an 82 and it had electronic advance. Can buykawasaki be wrong?

83 was the first year for the electronic advance on the 750's as far as I know.
If your friends GPz750 was a monoshock then it's an 83, the 82 was still twin shock.

buykawasaki.com is often wrong though, as am I

Yeah, it was monoshock. More likely my friend was wrong on what year it was.

Okay, thanks. I am new to this electronic ignition on bikes. All my other bikes have magnetos. I am guessing the ignitor (Capacitors I am guessing) and coil are separate whereas in a electronic ignition in cars they are one unit called coil pack...which act as capacitor and coils. I read the manual It either went over my head or the Haynes didn't explain it that well.

BTW I spent time researching the correct ignitor to go on my 1982 KZ750H but it probably doesn't make any difference. The firing order on all 4's are the same I am guessing. Correct or am I missing something?

The firing order is the same on all four cylinder KZ's (and probably all inline fours that use two dual-coils).

The ignitor is a transistor along with a few other components which does away with the need for a capacitor. It is not a CDI, by the way, it is a transistorized ignition. (CDI is capacitive discharge which is used on some older Kaws, but not on KZ's.)

more heat resistant built better vibration resistant
different vendor source of the guts T.P.I transistorized pointless Ignition (yamaha says T.C.I)

almost forgot higher RPM allowed too

I cant find mine ?? I have a 1981 KZ650 CSR I have no spark and I bought an IC igniter and want to replace mine but I cant find it please help

You have two wires in one sleeve coming out of the bottom of the small round cover on the right lower side of the motor. Follow those two wires till they enter a box and you have found the igniter. Probably a plug connecting those two wires to the ones going into the box. Should be two sets of wires going into that box, both ending in plugs.

Thanks I will check it out

Ok there is no IC igniter instead those wires are going to a Dyna III I could not find any serial numbers
