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.

Oil is getting in the air box from crankcase vent tube, I put the two hoses that go to the air box together then something started to smoke on the front of the engine. There is a filter? In the line I blew that out.

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?

Starting this build thread to keep up with everything on my build and hope to motivate someone!
I picked up this 2008 Yamaha Big Bear 250 2 weeks ago. A guy that I hunt with parked it at the hunt club for a year or so before I asked him if he wanted to sell. He said " fill my feeder and throw some batteries in my cameras, and you can have it". Sounds like a deal to me!
I have attached some pictures of how it sat under a tarp in the woods and when I got it home and cleaned up a little.

Greetings,
Have a 88 LT80 that been sitting for a couple years. Bought a new piston, cylinder and head. Installed these, rolled it over and it quickly locks up. Took carb apart. It was full of what appears to be 2 cycle oil. Cleaned it, but keeps locking up and 2 cycle oil continues to seap from exhaust port. When i installed new cylinder, I noticed crankcase was full of oil. I'm now wondering if that oil is what's getting sucked up into cylinder. Should there be no oil in crankcase? If that the case, how is crank and rod lubricated? Sorry, never worked on a 2 stroke. Thanks!
