I have a 1997 Yamaha Kodiak 400 4x4 it has a bad smoking problem the smoke on start up is a blue color and after it runs a while the smoke turns kind of blueish gray could this be the rings, the valves or something else, please help with any advice, P.S. there is also a little oil blowing out of the exhaust please help thanks.:GEEK:

could be just rings, could be just valves and/or guides, or all. try a compression test to narrow it down. if you have good compression, it could be just the valves or guides ... not sure how many lbs compression you should have, probably 130 anyway ... more than likely it is valves if it's blowing out the exhaust ...

ok Thanks for all the input I will do a compression test and go from there, it seems to have good compression when I pull on the pull start rope as it has a lot of resistance and is very hard to pull, but thank you for all the advice and I will do a compression test to make sure I will let you know what I find, Have a Great day.

      Quad to pull flail mower - Eiger, Kodiak, Big Bear ?
      By Fonne
      Hi 
      Is looking for a quad to pull a flail mower as my first priority, but also a bit of fun. 
      So its going to be pulling a flail mower on high grass / weed on a bumpy field at pretty low speed. 
      My budget is not high, so is mostly looking at a old Yamaha Kodiak 400cc / Suzuki Eiger 400cc or similar. 
      What machine would you recommend  ?  - Really want a solid machine since I am no mechanic but can perform a early service myself. 

      (English is not my native, hope it makes sense)

      I am unable to find a wiring diagram for this UTV.  When I turn the switch to on, the contractor does not engage.  The Brake pressure switch and the parking brake switches work correctly. What else should I be looking for?  All of the diagrams I have found are for newer models and the wire color coding is different.
       
      Thanks

      1988 Yamaha 350 Big bear No spark

      Fixing for a friend. Atv was at a different friends house to be fixed and he rebuilt the carb and had it running nice, then it shut off and no more. He replaced the key and the coil.
       
      So he got busy, so I am helping, I checked the wiring from the stator to the cdi, and from the cdi to the coil. All is good. I checked resistance on the pickup coil, good, and on the source coil, open. I buy a new stator (China) and the 4 prong plug only has 3 wires in it while mine has all 4. I checked resistance in the source coil and it's in the 300's. I pulled one of the old pickup wires out of the old stator and wire it in the new one. Still no spark.
       
      Why do the wires differ, I checked the VIN again and it's "J" for the year and I got a 1988 stator. Please help!

      99 Bear tracker no neutral or reverse light or start button
      By OldATVowner
      Just getting into this issue really. Been replacing solenoids but now I'd like to track down the problem. This time I'm not getting neutral/reverse lights or start button. Was on a creek ride when it started doing this recently. It cranks by arcing the solenoid and gives me no light or start button but if I crank with the pull cord....the neutral light and the button work. Turn it off and try to crank with the key and nothing. I'm looking into the safety switch issue tomorrow and re charging the battery. Just figured this was odd enough of a problem that you guys might be familiar. Thanks
