My 4 wheeler has been starting and running great since I purchased it. I changed theoil yesterday and afterwards I went to start it to let it idle so I could recheck the oil and for some reason it would not start. I let it sit for about 15min and tried again and stillnothing. I sprayed carb cleaner into the air intake and it started after a couple of tries. It ran great and started right up every time after. I tried it again later that night and it started right up. I went out to ride it this afternoon and it would not start. I tried sprayingthecarb cleaner again but itdid not work. I checked to make sure I was getting a spark and I am. I can't believethatchanging theoilwould stop it from starting. Any suggestions? Yourhelp is appreciated. Thanks, Joe __________

If the problem is starting a COLD engine only (IE it starts fine when warm, but not cold), its the intake valve. Check the intake valve lash. If the valve is tight, that means you have a crappy air filter and/or a loose connection letting dirt into the engine. Now that the hardness is worn off the valve, you're going to have to adjust the valve pretty frequently until the valve finally wears away.

The oil change might have been a coincidence.

      1999 Ranger 6x6 no start
      By realpilot
      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

      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

      2000 Yamaha big bear 400 won’t start
      By Mister907
      Hi guys, I have a 2004 big bear 400. Last winter while plowing the driveway, I heard a loud pop from the left side of the engine. It continued to run as I looked for leaky fluid, but then died shortly after backing it up and won’t start now. The oil light comes on when I try to start it, no noise or anything else. 
      No blown fuses that I can find.
