VinDecoderz says it's a YFM350 (Moto4 350) trim YFM350ER
Is that a Big Bear? Or a Moto 4? Or are they the same thing?
I've google'd around for information, and was able to find a (czech board in english) that had a Yamaha service manual for the YFM350X series, LIT-11616-YM-37. The 'Warrior' type. I'm trying to get something more accurate. I'm not sure which manual I need. Pictures included in this post.
I'm also looking to get a wiring harness for it.

I had a sudden loss of spark in my 1988 Suzuki LT300E quadrunner and we tried a new plug but still no spark. Then we checked the boot and there was no issues with it. I then took off the coil as I was going to get a resistance reading with a multimeter however I cannot find anywhere what the readings should be. The coil is a Mitsubishi F6T 411. Any help would be appreciated.

Hey everybody,
My proficiency is with Hondas and Yamahas make me see RED!
This bike is my brother in law's, it has 1199 miles on it and went from running great to dead with no start. Every once and a while it will start and sputter for 2 seconds. It is extremely sporadic when it fires but never runs for longer than 3 seconds.
Here is where we sit:
Brand New Fully Charged battery
Carb was cleaned with air hose and carb cleaner then into the ultrasonic cleaner with Aircraft aluminum cleaner
New Shindy Carb kit (made in Japan version)
Cleaned out petcock and gas tank
New 93 Non Ethanol Gas
New Spark Plug
It gets a spark through the spark test light every time
Bluish white spark
When holding the spark plug 1/4" - 3/8" away from head it will jump and spark to the head
Good Compression
Here are the readings:
Pickup Coil 519 Ohms (range 459-561)
Charging Coil 266 Ohms (range 270-330)
Lighting Coil 0.700 (range 0.702-0.858)
Spark plug Cap 10.58 Ohms (10kohms
Ignition Coil Primary Coil 0.5 ohms (range 0.18-0.28 ohms)
Ignition Coil Secondary Coil 8.20 kOhms (range 6.32-9.48 kOhms)
Would y'all think stator and pick up coil, rectifier or CDI are the culprit?

Hello, im looking for some input on this situation i have. My 94 Mojave has no spark, and i have no idea what it is. Ive replaced/tested the magneto, the pickup coil, cdi, the ignition coil. Even the key and Killswitch. I haven't tested the harness its self, but i have tried another harness and still nothing. The only thing i can think of is the fly wheel itself. I have found a lot of metal shavings in the fly wheel and have cleaned it the best I could. But nothing happened afterwards. I am truly stumped here and hoping some of yous could shed some knowledge/ideas that could help get this thing to fire.

Hi guys
My 87 Bear 350 won't start and could use a hand.
Turn key on and Oil light turns on and then slowly fades out. (I think this is key to this) No start, not even a tick.
battery and connections good
A Solenoid post jump turns it over
Neutral Safety Switch wire attached and seems good
It has not had a wire/switch on Rear Brake Pedal ever since I had it.
Any thoughts on some other things to troubleshoot this??
