2001 yamaha warrior YFM350x

Recommended Posts

I have a Yamaha warrior 350 and it has a brand new head and piston set. The piston has some scoring on the sides so I bought a new piston kit and it should be here tomorrow. The bottom of the cylinder head still has the cross haching on it but the mod and top don't and still looks good. Do I have to rehone it or no? No would be a great answer LOL.. need help. Also if I do is there another way to rehone it without a honing tool.. don't have one..

I don’t think you have to do anything  if your not happy with that answer then  run a cylinder honer through it. Amazon $20 bucks. 

Lightly run it up and down the cylinder walls nothing crazy.  

You should be fine with that.

Finally figured out what was wrong with it.. the crankshaft has a sprocket for the timing that has a DOT on it. I took the flywheel off and one way bearing and found out that it was not lined up with the timing mark that on the crankcase and not lined up with the cam sprocket that in lines with the Dash that's on the head. So I re-did the timing and fix the problem and it runs now. But I did trade it for a motorcycle a month later. I finally got to run but have to put some parts into it.

Messed up some wording.

      I have a yamaha big bear 400, tested all fuses and relays. When I turn on key I get nothing, no neutral light or headlights. Could it be the key switch bad?

      Hello guys! New to the forum, and fairly new to ATVs. I've driven them, but never owned one. Now I do own one. Just picked it up today. It's a 1999 Yamaha Big Bear 350. It's been through some stuff. The guy I got it from told me the previous owner removed the front diff because he didn't want to replace the half shaft. So it's 2wd, even though it's supposed to be 4x4. Lovely. I can deal with that for now.
       
      More importantly, I need to get it running. The carb needs to be rebuilt. The guy I got it from said he sprayed it all out and it still didn't work. I'm concerned he might have damaged it or not put all the parts back. I was looking at a replacement carb, and the OEM parts is $600. I'd rather not spend $600 if there are any other options. I have seen carbs on Amazon and eBay that are in the $40 - $100 range that say they fit. Anyone have experience with these? I'm going to get a rebuild kit for the current carb just to make sure that won't fix it.
       
      Thats the first thing with it. Secondly, it was completely rewired. I need to find a original wiring diagram so I can put it back how it was, with a key and all. Currently it's wired with just a rocker switch. Any sources for a service manual that would include wiring diagrams?
       
      Thirdly, is the Big Bear 350 a good atv? I picked it up for $700. It does start and run when you spray starting fluid into the air intake, so I am not concerned about the engine being bad. I plan to use it for the farm, running around and carrying things with it like minerals and feed and such. Not really for mudding and things like that. How good is the 99 350?
       
      I am certain I will have more questions as I examine it more, but that's all for now. Thanks in advance for the assistance!

      Just got a '98 Yamaha big bear 4x4 in working condition (so far). Looking forward for some good information on this site about how to keep it alive.

      So I dug my warrior out of storage replaced the carburetor with one off Amazon & it was running great. Last week it didn't want to start it would crank & I could smell gas but nothing. I replaced the starter,stator,solenoid,spark plug & coil & resistor but still not starting. Checked the stator and its at 30 ohms tried using starter fluid but nothing. I am completely lost and could use some help thank you
