Motorcycles, Snowmobiles, Go-Carts, ATV's and Golf Carts - no spark on big bear

Hi,I have an yamaha big bear 350 1997,and the bike was in storage for 2 years.I want to fix it for a gift to my daughter.i have no spark and the coil is good,I would like some help please.

someone have a idee what to check?
thank you

You know what? Those things come equipped with a kill switch or two. I'll bet it's deeped six any spark. Check those switches and try again.

I ordered the repair book but I w'ont have the book before next wenesday,can you tell me where I can find those kill swich on the bike
Thank You

Those kill switch icons should be universal, at least in recent years. My 2006 Honda Rancher shows a bolt of lightening surrounded with a circle and a slash part way through. It's a slide switch located on the left handle bar.

One other thing, those machines have to be in neutral or you get no ignition either.

Thanks for answered me bs5,last night i made some test an on the wire for the plug,I put a mutitester on the plug wire and the end of the plug cap wire where the spark plug go in and I have no ohms betwen those two,and inside the plug cap I saw a screw,a spring and something that look like a fuse(is it a fuse or what).

Is it possible if the cdi is bad ,that why I have no spark,because when I test the orange wire on the coil I have no power on this wire,and this wire goes to the cdi box.

so is it the plug cap,or the cdi,because everthing else is working,(light,heating handle,starter,etc,etc.

Ps.I took out the two screws of the cdi and behind the cdi I saw the plastic has melted,
Thank you

Ok,in the plug cap assembly I saw a resistor element.should I have a reading when I test this resistor,because now when I test this resistor the tester read no reading(no ohms)when I test each end of the resistor.
Could it be my problem for not to have any spark on the plug.
Hope to have a answer,
Thank You

my bet is you need a new stator.....that also controls spark

(I read the entire thread)

If it worked when you put it away, then it's got to be one of your switches. A CDI, coil, or spark plug wire won't go bad by sitting unused.

In addition to the engine 'Run/Stop' switch, you must be in Neutral - and not reverse (there is a switch and wire to check for that). There is also the Key Switch.

In some 'Child Safety' models, you must also have the parking brake on.

I recall - BONE-C from my daughter's safety training: Brakes On, On/Off keyswitch On, Neutral, Engine shutoff switch set to RUN -- Choke

Also understand that any of these safety switches may have failed, gotten dirty, or had a spider have a heart attack and die across the set of contacts.
