Wont Start

So I rewired the entire bike , new stator , new coils ,new Dyna S ignition, new plug wires and new plugs , and I fixed the problem of not having any spark , I now have spark from all fpur plugs but the bike still wont start? Timing ? Any ideas as what is the next step to take to get this thing to fire up ?

Thanks in advance

Be sure you have the wires on the correct plugs. 650's are oposite of the 900 and 1000. Left Coil is for 2,3 and Left for 1,2 . Also check that the dyna pickups are going to the correct coil.

When sitting on the bike left coil is 1,4 right coils is 2,3 ?
Is that right you said left left .

Ignition Coil Primary And Secondary Wiring

Ignition coils on the 80’s Kz1000,Kz1100’s and Gpz1100’s are wired the same, that is as you sit on the bike, the LEFT ignition coil primary(small wires) are two wires, RED and BLACK. The secondary (or sparkplug wires) go to #1 and #4 sparkplugs.

The cylinders are numbered left to right as you sit on the seat; #1,#2,#3, and #4.

For the RIGHT ignition coil, the primary wires, again are two wires, RED and GREEN, with the secondary going to #2 and #3.

The RED wire gets it’s voltage from the run/stop switch on the right handlebar switch pod.

The BLACK and GREEN wires connect to the IC Igniter(if the bike has the Kawasaki supplied electronic ignition) it actually gives the coils their grounds to fire the sparkplugs.

Primary(small wires) side of the coils will read between 1.8 to 3.0 ohms.

Secondary(sparkplug wire ports)side of the coil will read between 10.4K to 15.6K ohms.

Keep in mind the wiring will be reversed for the 650's and 750's, that is the RIGHT coil primary will be two wires, RED and BLACK with the secondary(sparkplugs) going to #1 and #4.

The LEFT coils primary wiring would be again two wires, RED and GREEN, with the secondary(sparkplugs) going to #2 and #3.

These engines have what is known as a “Wasted Spark” that is, a sparkplug will fire during an exhaust stroke. It does no damage and many other motorcycle engines have this design.

650 is backward from the 1000. The left coil as you sit on the bike fires 2 & 3, the right coil fires 1 & 4.

Regardless of where coils are hanging on the bike, it's critical that wire from left-hand (rear or 9 o'clock) Dyna-S pickup module connects to whichever coil fires outside plugs 1 & 4; and that wire from right-hand (forward or 3 o'clock) Dyna-S pickup module connects to whichever coil fires inside plugs 2 & 3.

Good Fortune!

Also critical that the magnet embedded in the Dyna-S rotor faces the left-hand Dyna-S pickup module when the F mark for cylinders 1 & 4 appears in the inspection window.

Good Fortune!

Thanks guys I think I got it wired backwards , I will check when I get home from work and report back ....

This illustration is for Kaw large fours without the KZ650's blue wire running to the oil pressure switch.

Good Fortune!
