stator?

[8vo fan]

Hi guy's it's been a while.
Anyway, My '97 700sx has a spark issue. It starts up cold just fine, Doesn't miss while riding, Goes through about 6 plugs in 100 miles, won't start warm. If I disconnect 1 coil it starts easily on 2 cylinders. Sounds like stator to me. Low speed coil tested 84 ohms. High speed at 434.
Any ideas?

I don't know about those numbers, but 97's are notorious for weak stators.Very good chance thats your problem.

The stator is testing within specs. That is were I'm confused. I will probably buy a new stator but, $300 is a little hard to stomach if that is not what is wrong.

check resistance on the spark plug caps. your stator is within spec.

New wires, any two coils can be plugged in and I have awesome spark. Plug a third one in and I can't see any spark at all.
The resistance was tested well below 80deg. I have no way to get it that warm for about six months! I could try warming the engine up and then testing.

got a new stator last year for $153. just pulled out my receipt and went back to the website and they are $226??? WTF the price goes up 75$ in 1 year??? I would go with new. I bought used for $80 and it went out the next season.

Just wait until yamaha says "no longer available" These sleds are 10 yrs old+++.

I tested the stator again at around 80 deg. still tested within specs. The flywheel was pretty rusty so I cleaned that.
I guess I will test all the wiring and switches next but, this motor has had the same problem in 2 chassis. the only thing I changed with the motor is the cdi.

move wires around at the cdi box while it's running.
