1988 Yamaha Big Bear 350 4x4 - Spark Plug

Recommended Posts

I took my 1988 Yamaha Big Bear 350 4x4 out for a ride today and it started to miss fire, it starts great, sounds great at idle, but at high RPM it starts to miss fire.

I want to change the spark plug first, can somebody recommend a plug? What would be the best plug to put in it? I was thinking an NGK DR8EIX

Does anybody have the procedure to adjust the carb?

what should I check if it isnt the plug??

      So I have an 89 Yamaha moto 4 250cc and when I ride it, itll get hot after like 10-15 mins and then will just die and turn off.
      It's has new carb rebuild, new air filter, new battery, new spark plug so I don't think it's a crack in the spark plug
      Can anyone help me?

      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!

      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.
