how good is the spark? when turning over the spark should be rapid and brilliant blue ... if not and it hiccups or not completely blue, could be stator and/or pick up coil ...

I changed coil off one that runs and it looks kinda white the spark but it don't look bad i looked at the other one and it looked about the same

the stator makes the spark, it is inside the cover by your left foot sitting on the bike, it is an easy fix, the spark being white is weak, if changed it will be blue. stator and pick up coil are sold together, both inside the cover, you might be able to buy just the pick up coil and try that, sometimes that is all that goes on them ...

i had the same problem on a 91 big bear and changed it out and never had to look back. from what i heard, yamaha had stators that didnt hold up that well. but the aftermarket ones are the way to go. ebay has alot of good deals on them ...

Ok i pulled stator out of parts machine and i pulled carb from one i have that runs good but as soon as it gets warm it dies i thought maybe something wrong with carb when i pulled it so i took it off myn and put it back on running one and that one ran great so there's something still wrong with myn wat could it be?

leakdown/compression test might be ok to start run but once it warms up too little compression to run.

fuel tank vapor lock? is tank clean and is vent out of top of gas cap clear? my lt160 did same and that was the issue. also check vacuum lines from carb to airbox and motor.

      I have a 2000 warrior thats seems to run fine. But I am having a problem with the gas boiling in the tank. Does anyone else have this problem or can anyone give me suggestions on how to fix this issue? Thanks Bill.

      Ok i am not quick to jump on a forum and post a question without doing my own part and trying to research and solve the problem myself but I cannot find any definitive information anywhere about my problem. I have a Big Bear 350 that I picked up very cheap which had been sitting in a field for years. I am not new to building wheelers but this one has me beat. After rebuilding top end and replacing the carb it fires right up. The vin has some number worn off from being next to the shifter but from the parts in the clutch i assume it is early since 87 parts seem to be the only ones that match. Thats when the plot thickened. 
      Reverse works fine but when in the forward gears it would not go past 1st and was hard to get into neutral. ie. a it took a million clicks up to thump into 1 and as many down to find neutral. still never getting past 1st. within minutes i could hear metal screeching and whirling around in the clutch side of the motor. I took the cover off to find that 3 out of the 4 springs on the centrifugal clutch had broken and were shredded. Also the black mechanism that the pawl on shift shaft grabs moves was loose so it wasnt always grab to change the gear on the transmission. I tightened that mech, and replaced the springs assuming it would solve the problem since the gears were not actually changing from the lever and the carrier should obviously not only have 1 spring left. 
      After putting everything back together it did go into 1st fairly easy but then i again couldnt get it back to N without a million clicks down and couldnt get it to go past 1st. I did one time get it into a higher gear who knows what one but i gained some speed and dropped rpm.
      If i jack both the front and the back wheels off the ground and run the motor it becomes much easier to shift and i can get it to run through the gears pretty well. Usually going into N without a huge fight. not perfect but it does hit neutral and roar while spinning the wheels instead of gain rpm and with the power. 
      I have tried every possible position on the clutch adjustment screw without any noticeable result. I think this could potentially be where my problem lies at this point.
      does anyone know if the case is supposed to be threaded? because mine is not. obviously it seems as though it should be since every other bike ive touched has been. i even took the cover off my quadrunner to make sure it wasnt crazy.
      when the screw is adjusted and the jam nut tightened the screw will just slide back out since there is no threading in the case. accomplishing nothing. 
       
      Does anyone have any insight on any of this? Are my plates stuck, Centrif clutch worn out, case stripped or something else crazy im over looking?

      On Wednesday, September 18, our ATV was stolen from in front of our house after the locks were cut. This was around 2-3:15 AM.
      We realize the likelihood of ever finding the four-wheeler again is slim to none, but we had to try and put the word out there. We have put countless hours in to restoring this Banshee. It was more than just a passion project, it also was our investment for a down payment for our future house. We are devastated and beyond heart-broken. If you see any suspicious postings on Facebook Marketplace, Letgo, Craigslist, etc., or have any other information, please contact us or the Prince William County PD.
      *Update* We received a tip last night that it was possibly posted on Facebook Marketplace around 8AM yesterday morning with only pictures of the front and of the back of the ATV. The description only said: PM for more details. This came up in someone’s FB Marketplace feed that has it set for a 50 mile radius from Hartwood, VA. She also has her feed set to automatically translate everything into Spanish, so It could also possibly be posted in Spanish.
      WHAT WAS STOLEN:
      2004 Yamaha Banshee YFZ 350
      White plastics with bright green and pink graphics/stickers
      STOLEN FROM:
      Prince William County, Triangle, Virginia
      $500 REWARD FOR INFORMATION LEADING TO RECOVERY. BONUS FOR CONVICTION.

      Hi guys I have a 2003 Arctic 250 4X4 it starts idles and runs great for about 10 min. then it spits and sputters and dies but it starts right up like nothing happened idles good till you give gas and it does it again let off the gas and it's idling great again this goes on for about 15 to 20 min. and then it takes off runs good all day like nothing was wrong.
      I cleaned the carburetor it looked like a new one inside found a little gunk in one orifice, new air filter no crimped lines air line to tank good I did put a meter on the battery idling it said 16.5 V that's high I think would a voltage regulator cause this?
      Suzuki shop wanted to sale me a stator for $556.00 but said it could be something else also thought I'd see what you guys say about it
      Thanks

      I just recently bought a 1994 Yamaha Timberwolf 4x4 from a buddy who had the wheeler sitting in his garage for 7 years. I got it home and fired it up pushed it out of the garage and tried to shift it and it wouldn't shift. First it would click like it was shifting, but the wheeler wouldn't move and when I hit the gas it revved up like I was in nuetral. After trying some more it became stuck in 1st gear and wouldnt shift at all. But it later broke loose agian and acts like it is in neutral again. I took the motor off the machine to make it easier to work on.After asking friends they were convinced it was a clutch problem but after opening up the casing for the clutch I don't see anything out of the ordinary and am concerned that it may be a transmission problem. Any help would be greatly appreciated thank you.

      I just got a 1991 Yamaha Moto 4 for my son and I am looking for a service repair manual. I know that the timing chain needs replaced.
    • By alexcross324
      Hi all, I try to find this manual in the threads but you have a lot of stock here
      Cannot find this particular manual.
      I found it for YFM200 but not sure if they are the same.
      Thanks if you could help me with that.
      Im new here so if I did something wrong, please tell me.

      I have an 04 ltz and it started sputtering a little bit while going down the road and I was low on gas so I just figured that's what it was. But now I can't get it to start I completely cleaned the carberator put a new spark plug and coil pack in it and all it does is turn over. It has compression it's getting fuel and it is sparking but all it does is turn over any idea what it is??
