2003 YAMAHA RAPTOR 660R Carburetor problem

It may be getting too  much air,  running too  lean to  start  .. Try  replacing the air filter  and other stock inlet air components and see it if starts and runs much better. Some quads  need the  air filter installed to  run  properly. Several  members have run into that  problem  before.

As a general rule, spraying carb cleaner through the carb into the engine does no good. The carb cleaner goes directly into the engine without cleaning the passages in the carburator. If you suspect the carb is dirty, you can either remove it and clean or try a gas treatment such as Seafoam or Mechanic in a Bottle.

Thanks I'll try that.

      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?

      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?

      Hey I have a 1997 big bear 350 4x4
      I replaced the shifter shaft and the shift arm linkage and the rod when I installed them all I was unaware that you had to line the dot on the shifter shaft with the gap on the linkage arm gap put it all back  together and rode it I can't get it to shift in the right gears  I can move the shift cam by hand and goes in different gears but with the shifter shaft in it riding I can't put it in R or N 
      Anyone know how to line up the shifter shaft and the shift cam s
