[buggyboy]

Hey everyone!! I'm a newbee here but it looks like an awesome site! I have a problem and i'm hoping somebody can help! I was driving My wheeler the other day and i climbed a steep hill in the gravel pit. Jumped over the top and when i landed it died. I towed it home with my sons KX80(that was cute lol). Got it home and started checking i had absolutly no fire checked wires can't find anything obvious wrong. switched coils cause thats what everyone says was the prob. but didn't help. any body got any ideas??? any and all help is appreciated!!!! Thanks!

Got gas? Just bought a 93 warrior have not had that problem yet, I am taking it out sunday though.

Also change the spark plug, I meant to put that with my first post.

For starters...Im not stupid! and second...you dont need gas to have fire! Good luck with your wheeler

[screamer25cc]

no you don't, but gas helps to get it going...Did you hit the red switch by chance...? Do you have it in neutral>? Just asking, yeah it's happened before for got to put it into neutral...lol ...I didn't say you were stupid just trying the obvious...

I'm assuming the engine turns over. I would say that when it happened by landing after getting some air something got disconnected or knocked loose. When you checked the wiring did you remove the tank and check all the electrical connections?

True, but has nothing to do with no spark.

It would not even turn over if the red switch was in the off position.

Yamahas are bad about the pick up coil going bad look on the left side of the motor gear shift side and there should be a green and red wire coming out of it maybe striped wire anyways thats most likely the problem

check it with an ohm meter it should be around 150 or higher if it reads like 25 m ohms or 2.5 thats what it is send a pic. of the wires coming out and i can help you

unless something came loose in the key switch sometimes that happens

hope this helps

[buggyboy]

thanks for the help guys i will check the pick up coil i really hope thats the prob. I got all the plastics and tank off can't find any bad connections. the problem is b4 i got it someone re wired it all so it doesn't even have the red switch. no kill switch either just the key. but it has worked fine since i have had it in early spring till just the other day. i just hope its not the CDI. and thanks for stating the obvious too some people wouldn't check that stuff i guess. i'll let you know how it turns out!

[swampgrass]

its sounds like the pickup coil to me the cdi boxes only go out when you take them to the dealership if u no what i mean

[buggyboy]

Sweet Thanks Man! hopefully thats the prob!!

[2fun]

Sounds like these guys are giving you a hand. Just wanted to say welcome to

[swampgrass]

if it is the problem when you go to fix it turn the bike on its side so you dont loose any oil plus it makes it easier to work on it

[buggyboy]

ok everyone finally another day off, and i can look at the bike. i tested the pickup coil and it reads like 460 OHMs i tested a new one and it was almost the same. so i assume thats not the problem. But when i went to test the sorce coil it has no reading at all. i checked the wires going to it and there fine. so i'm thinking there should be a reading there of some sort or atleast a circuit between the two wires. am i correct? do u think this is the prob?

[swampgrass]

yes you are right thats why you check it in ohms 460 sounds like alot to me i wish i had a manual because i didnt think it was that much any ways


source coil sounds like the problem. alright keep me posted

[dillmonty]

source coil should read 270 to 330 ohms.

[fouz]

what color is the wire coming out of the engine? im having the same problem. i just wanna start at the source and work my way out.

Sounds like what plagued me at one time. Take a good look at reverse lever switch wiring.Good luck,
