maybe over filled it and then it stop and then i replace STATOR
ASSY .. can any one help me on this one

 

No sprak de eenglish?

Sorry, my secret decoder ring is broken today.

What kind of motorcycle is it? What year?

Is it a 2-stroke or a 4-stroke?

Does it have a battery?

The only "Big Bear" motorcycle I ever heard of was an old Yamaha, made
in the 1960's, and it wasn't a 400, it was a 305cc 2-stroke model that
had ignition points and needed a battery for the lights.

It's normal for *some* 4-stroke motorcycles to have oil inside the
stator cover. If a 2-stroke motorcycle has oil inside the cover, that
usually means the oil seal behind the stator is leaking.

Does this engine have mechanical ignition points or does it have a
magnetic pickup coil that sends a signal to a "CDI" or ignition
control unit?

Mechanical ignition points have to be clean and dry and properly
gapped and the timing has to be set when you install new points.
Ignition points won't work if they have oil on them.

If you have an electronic ignition, the magnetic pickup coil will
still work OK even if there is oil on the pickup.

Electronic ignition systems never go out of time and it is rarely
necessary to replace the pickup coil, just check all the wiring to see
if it is clean and the connections are tight.

CDI's (ignition control units) either work, or they don't, there's
seldom any time that they work intermittently.

 

Hey, if he can't even communicate in English, much less give basic
information like what bike, why bother?

i have big bear 400 no sprak i replace the IGNITION COIL ASSY and

Why bother? What if that guy was you and you needed help getting
something you had running? I am sure you would be trying to find an answer
and I am also sure you wouldn't like reading snide remarks either. If you
can't help, don't.....just because you may know something he doesn't in this
area, doesn't mean he isn't smarter than you..... as for me, I learn alot
just reading these newsgroups. Give the guy credit for wanting to learn
about what he owns... I am sure he will apreciate your help.
At least the guy is trying to wrench his own bike. Its true, we need
more info to help him out better.. I am sure that info will be forthcoming
so he can get the help he needs. Plese be a little more patient.

Ok.... I am putting on my flame retardant suit now....

What is the meaning of my life? Why am I here? Helping strangers in
need is part of the Judaeo-Christian ethic. Mitzvah. Charity. The
Golden Rule. What Hillel said to the Roman soldier who was tormenting
him. The parable and paradox of the Good Samaritan. Finally, helping
other motorcyclists is part of the tradition of brotherhood of all
bikers.

What is the meaning of *your* life? Why are you here, if not
to answer messages from cyberspace?

 

Since I'm asking folks to take time out their day and help, I'd be sure
to at least communicate what my problem was, with as many details as
possible, so as not to waste anyone's time. It's simple respect to folks
that might help.

A barely readable post is rude, ignorant, illiterate, and just gets
people to poke fun at you for looking like a moron.

That's why I would compose a post in coherent English, to avoid such a
situation, and to avoid looking like I have the IQ of a potted plant.

If the guy can't even say what bike he has, then what's the chances
he'll actually try what I suggest, and relay the results in a form where
I could help interpret what's actually going on?

Probably nil.

So like I said: why bother?

-gc

 

He just sounds like the retard that sprayed WD-40 on his brake pads,
after I suggested that might not be such a good idea.

Or like the guy that put an aluminum pin in his brake torque arm, and
was so surprised when it sheared off and his caliper swung around and
locked up his rear tire.

Some people you just can't help. I was saying if he can't write a
coherent post then he probably can't follow simple instructions.

-gc

 

Try and help, at least a little bit, before you judge a
person to be beyond all help.

instructions.

Have you ever watched after race interviews, where the
winner of the race could hardly express himself in English?

Yet the guy won the race. Being semi-literate in another
language is better than being completely illiterate.

 

Jawohl.

 

Sir;.... Gene C, is a regula puttnucker plant.......

Perhaps Gene will experience his own karma by needing help in a
foreign country where he doesn't speak the language.

I paused to reload my camera in Florence once. When I looked up, the
tour guide had taken the group I was with off in an unknown direction.

I know about 10 words of Italian, and "spaghetti", "pizza" and
"lasagna" wouldn't cut it.

I did know that they were headed for the "Piazza di Santa Croce", so I
kept saying "Piazza di Santa Croce" to Italians on the street and
looking helpless, so they pointed me in the right direction.

Nobody threw rocks at me, or told me that I was an idiot for not
speaking perfect Italian.

Or, if they thought badly of me, they didn't indicate it.

 

Is this the Yamaha Big Bear 400cc 4-stroke 4-wheeler?

It, like most 4-strokes, carries oil in the ignition.

I will proceed on that assumption.
Check and clean every connection between your wiring harness and the
coil, stator, and switch cluster.
After polishing the connectors, I use di-electric grease on them when
I plug the wires back together. It will enhance and protect the
connection of the wires.

While the switch cluster wires are disconnected from the wiring
harness, check the switches for proper working order, using a
continuity tester.

Look for a frayed place in the insulation of the wires of the wiring
harness.

You should also remove the coil and clean both it's mounting surface
and the frame, at the place where the coil mounts to it.

Check the spark plug wire and cap. The spark plug wire will often
corrode at the place where the spike from the spark plug cap screws
into the wire.
If the wire looks corroded at that place, just cut off 1/4" (5mm or
so) of the spark plug wire, and screw the cleaned spark plug cap spike
back onto the "now fresh looking" spark plug wire.

Some models will allow one to unscrew the spark plug wire from the
cdi and do the same maintenance at that place.

One more thing: If your bike quits recharging the battery, the
first thing to check (after the connections of the wires to the
battery) should be the connection of the ground wire to the engine or
frame. This is the most prevalent cause of a charging problem on
atv's and m/c.

Good wrenching and luck to you!

Not sure if the bike has a cut off switch, but if it does, you might
want to check that...just a thought

Anyone can make typoos. <VBG>

I neglected something in my post.
Down below, it should have read, "Check and clean every connection
between your wiring harness and the cdi (engine control module, or
"black box"), coil, stator, and switch cluster."

It *Whaaa-aat*?

 

Can you say "sprag clutch"? It needs oil, as does the needle bearing
in the starter idler gear.

This machine is a Yamaha ATV called YFM400 Big Bear. it comes in 2WD
and 4WD models.

The alternator stator and rotor run in an oil bath, and so does the
ignition pickup coil. So the presence of oil inside the stator cover
is normal.

The engine also has a recoil starter.

 

Did anyone else beside me just get a mental picture of TOG as Moe Szyslak?

Pardon me. I should have said "Like most of the 4-stroke engines in
dirtbikes and quads.", which is really all that I know about.

I keep reading all the rest of ya'lls stuff to learn more about
street bikes. (especially Mark and John's posts.)

And, I found two different varieties of B-12. I had trouble figuring
out which I needed for my old '81 XV920RH project, so I got both.
Any help available with that difference?

TIA

Try looking up the MSDS on each version (perhaps listed by part number?)
The MSDS must be made available to you if you request it, and it will
detail the contents, at least to the extent that you can determine
whether the different versions have different properties.
