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.

      Hello I am new to this site and I havea problem. I have a 1987 big bear 4x4 that will not spark. I tested pick up coil per repair manual and I tested my new coil both ok. It puts out 9 volts at the coil but It is reversed polarity. So when I hook my meter up to it she shows -9 volts while cranking. When I put a test light  on it it flashes. Being an electric system this should tell me something but I don't know what its telling me. I have yet to meet one i could not fix but this old girl has me stumped. Any help would be awesome. Thanks to all.

      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 have an old yamaha bear tracker that was given to me from an old farmer I know. I decided to refurbished it and fix all the quick fixes on it. I am pretty sure that it is either a 1999 or 2000 based upon the original wiring harness. Little did i know when I bought a new to me wiring harness from ebay that it was from a 2003 or 2004. My question to everyone is do I need to have all the stop switch assemblies hooked up? I think there are three on the 03/04 models and only one on the 1999 to 2000. Any help I can get for this would be great. I haven't run it yet due to the motor and crankcase is in two totes.
