What would make this bike always run rich?

If there isn't enough voltage...than my coil's going out? Again, the
points / condenser were just replaced.

Thanks

Shit.

Luckily I have a set of spare carbs, although I have no idea the
condition they're in, maybe i'll throw them in there and see what happens.

And theres no way to get this gum out?

Thanks

Ultrasonic cleaning is generally accepted as the best way.

It's a bugger, because you can blow out the jets, etc, but the stuff
still gets stuck in all the little galleries inside the carbs
themselves.

 

Measured compression today when hot, 180 psi in both cylinders.

 

Coils either work or they don't. They sometimes have intermittent
connections inside that will drive a rider crazy. The engine
mysteriously quits when the coil gets hot.

The engine only needs about 10,000 to 12,000 volts to make enough spark
to light the fire if the carbs are adjusted correctly.

That amount of voltage should jump 1/4 of an inch easily.

You have to keep after your ignition points, cleaning and re-gapping
them every 4000 miles.

Kawasaki used a voltage dropping resistor in series with 6 volt coils
on some of its models. Check with www.partsfish.com and
www.buykawasaki.com to see if you can find out anything about such a
resistor on your Kawasaki.

Also, google around the web for "kawasaki" +"resistor" to see if
anybody has discussed voltage dropping resistors for your machine.

The full 12 volts goes through the resistor and makes a hot spark for
starting. As the resistor heats up, the voltage is reduced to 6 volts.

It's a kind of race between the resistor and the coil, to see which one
heats up first.

As I recall, the 6 volt coils had about 1.5 ohms or 3.0 ohms
resistance, and 12 volt coils would have about 5 ohms resistance.

If your motorcycle once had a firewall resistor and somebody removed it
and ran the wire straight to a 6 volt coil, the coil would get hot and
the engine would start backfiring out the exhaust pipe.

Loud booms, like somebody shooting ducks with a shotgun.

 

i agree with the older gentlemen with the mixture screws all the way in
theirs somthin not right with the carbs stop looking at your spark. blue
spark is good as you said change the carbs or take it to a known good dealer
for a good carb soaking and cleaning. with only two carbs i would say the
cost would be around 200. but if it doesnt run just right when you get it
back then the problem is on their shoulders to do them over. on the other
hand i know all the stories they can come up with as to why it doesnt run
just right when you get it back. thats why i would you get a good tech at a
good dealer.call them and get a qoute on a carb clean then their commited to
the price.mabey even take it in and ask them what it would take to get it
running right a est. they will have to stand behind what they tell you.

 

On the spark side of the question, old/worn/heat damaged plug wires will
leak voltage, leading to a weak spark. (Sometimes you can actually see this
problem by running the engine in the dark -- leaky plug wires will actually
show!...)
Also, if you decide to replace the coils, why not go with after-market
hotter coils...
Another old trick for older engines is to replace the spark plugs with ones
that are 1 heat range hotter than stock. If your engine does not have a
hot-running problem, this can get everything burning cleaner. (If you're
worried, just change back to the stock plugs after you've burned all the
crap out of the cylinders...) If you can find it, get one of those full
color charts that shows all the possible looks that spark plugs can have
that tell you what's going on inside...
