1. Is the stator necessary for starting bike? I got a NRC case cover and had to drill and tap the mounting holes so Im thinking it might be off and not supplying any power. Is there a way of testing the stator?

2. What is the order for the spark plug wires. I have, looking at the front of the bike starting from the left, 1, 2, 3, 4. Is that right?

I wanna say yes to your first question. The stator is attached to the pick up coil and if that is not seeing and sending a proper signal then it could prevent the bike from starting.

The second question...

If you are sitting on the bike and facing foward the plugs are 1234 from left to right.

Hope that helps

Bike will start without the stator.
Bike WONT start without the pickup coil.

To test your stator, hmmm, assuming your rectifier is okay, you need a multimeter. Put it on your battery, with the bike running the voltage should be 12.7-13.5

I always thought the spark plug wires went 1,3,2,4......but I could be wrong.

What I did for the spark plugs is the longest marked 4 is the furthest away from the coils. Then just went on down according to length of cable.

Ill try the other way, but I don't think it will work because the 1st cable is really short.

The stator is good. I think the fly wheel is hitting it tho.

Page 8-4 in the following link shows the coil/wire setup

Firing order is 1,2,4,3. With coils feeding two cyclinders each this is a 'waste spark' ignition. This means when #1 is firing near compression stroke TDC, # 4 is also firing 360° away on it's exhaust stroke. Same for #2and #3.

Basically as long as the coil nearest the right side frame rail has spark leads going to #2 and #3 and the other coil feeds #1 and #4, you all good.

And, a couple of the few industry standards is "right" or "left" means as sitting on the bike, and #1 cylinder is always the one closest to the ignition/flywheel.

If the flywheel is hitting your stator that isn't good.

Technicaly, you are correct on this, but it does not matter. While they are two separate items, you can not replace only one as they are hard wired together. So replacing the stator means you are also replacing the pickup coil. At least for the FZR600.

Do a diode test on the stator also.

So, I did a little test to figure out if the stator is hitting the flywheel and it is not.

Ive checked ALL spark plugs by pulling them out and turning over the engine with the plugs grounded. They all have spark. The wires are good and going to the right plug too.

The only thing I noticed that could be wrong was that the plugs were a bit wet with gas. I cleaned them off but Im thinking Ill have to replace them soon. Im also going to lower the float hight and lean the needle to see if that helps.

I am unclear here. Does it start/run?

It does neither.

All it does is turn over, but never starts.

Did this no start condition just start to happen?

Did it just start after the new NRC cover and the drilling of holes to mount the stator?

Are you positive that the pickup/pulser coil is in the proper position? (it is the separate little black box unit that is on the same wiring loom as the stator). The pickup coil is what determines the 'when' of the sparks.

if you are sure that the pickup is in the right spot, and it won't start with new plugs, I would suggest you switch the primary ignition leads from one coil to the other (the small wires that trigger the coils) and try it then.

It did just happen after the stator cover. Before it started fine.

I replaced the battery and leaned the needles and now am getting some kind of combustion but it still wont fully start. The stator is giving off 5.5v when Im trying to start it if that means anything. I will try the ohms test soon too.

You had to drill new holes? For the pickup/pulser coil too? You replaced the cover, why? Drop the bike? Are you sure the flywheel is straight??

Otherwise I still think your pickup coil is: a) too far from te flywheel (excessive air gap between it and flywheel) or b) not in the proper location to properly time your spark.

If the air gap was excessive I believe you would have no spark,or it would be very erratic. The position would have to be way out to cause a no start condition.
Do you hear your fuel pump clicking when you turn on the key ?

So I just figured out that the flywheel was hitting the pulser and not the stator. I must have drilled the holes too low. In any case, I have a stock stator cover coming to me so I can try that too. I think you hit it on the head reelrazor, it had everything to do with the pulser. Im going to go work on it now, Ill keep this tread updated.
