I recently purchased a raptor 80 for my grandson for  christmas. I am trying to make sure it is running properly. i have rebuilt the carb and adjusted the carb idle then the mixture to middle of where it runs rough and it runs great for about a min or 2. then it stalls out. I can usually choke it and it will start so i feel it is lacking fuel. the fuel shutoff valve has been changed and i checked it for good fuel flow.  any ideas of what to check next. I am planning to vfy fuel float height tomorrow. I visually checked it by turning carb upside down when i had it apart and it looked level. any ideas are appreciated. 

 

Thanks.

Just an update, the raptor is fixed. after cleaning the airbox and filter and removing exhaust to vfy it was clr. after reinstalling everything it appears  to be running much better. I have no explanation but will take it. 

 

 

thanks

      Raptor Pre-ignition?? (Maybe)
      By jordan_ATV
      I got a 2005 350 Raptor Special Edition and I'm dealing with a no start issue; the weirdest thing is when I'm cranking it fires and slows down showing signs of pre firing, smoke shoots out the carburetor every time it sparks. every electrical part (CDI, Rectifier, Stator, Coil) has been swapped out from previous owner, the top end of the engines all new and I cleaned the carb out, anyone got any ideas or similar problems, also is it possible to have a bad spark timing

      2007 Yamaha Grizzly 350 carb mixture screw
      By Louznmemind
      (Question is at the end if you want to skip my blabbering) I got this unbelievably well taken care of Grizzly 350 in for a carb clean, it belongs to an elderly couple that bought it brand new in '07. Apparently whoever has been doing their oil changes for them never checked the air filter..
      Obviously it got debris in the carb, it would still run but only idle with slight choke. I've taken it apart and cleaned it, have new o rings, gaskets, etc. As far as the mixture screw is concerned, I'm assuming I obviously need to remove the plug. I'm mainly a lawn equipment guy, I've worked on slide carbs in the past but never an unmolested one with the plug still intact. I hate to mess with it as the carb had very little debris but I'm sure the o ring needs to be replaced at minimum. Finally, the question: what's the best way of removing the plug? I DO NOT want to mess up this carb..

      Purchased a Yamaha 350 Big Bear I don't see any VIN number on it
      By Olchap
      Hi, I am new to  this forum and I am happy to be here.  I purchased a Yamaha 350 Big Bear without a title and I cannot find a Vin number to find out what year it is.  I am hoping someone here can help me identify this atv. I checked on the main frame near the front A-arm left side found nothing.  I checked up near the radiator and found nothing.  Where else should I look?  See image below.

      Suzuki king quad 300 idles great but Boggs when you apply throttle
      By 97kingquad
      Okay so I bought this 1997 sazuki king quad from a guy and he had it for a few years. 
      He had it registered and on the trails last year but he said it bogged and backfired when he would try to drive it. so it sat for a year. 
      I bought it for 800 bucks and got it running that night and it ran great for a few days 
      But I parked it the other night and went to start it again and it was really hard to fire up and when I did it was bogging and idling high then low again.
      So I took the carb out and cleaned it (ended up doing it twice because it was still doing the same thing) 
      Now today I have it running slightly better, but it is still like 20% 
      I have been looking it up and trying to figure it out but I can't find the issue, has anyone else had this problem? I'll attach a video of it running and giving some throttle
