I picked up a 1990 Yamaha Moto 4 350 from a buddy in the past two weeks. Still runs very well and is the first ATV I’ve ever owned. It is a nice utility ATV that my kids can have fun on. Wondering if anyone has an owners and service manual for this ATV.  I’m a DIY guy that wants to go through and maintain the ATV. I just gave it a updated paint job (photo attached). Thanks for the help.

Welcome to Quadcrazy Big E. Nice looking bike for it’s age.   I like older bikes, they are fun to work on without all the electronics. 

So you should be able to find a manual in the downloads section of this site.  It’s the tab on the top right side and go down to the download tab and it’s self explanatory as far as looking for your bike.  It should be there or a year close to it.

You must have at least 10 posted items before you can have access to the manuals but you won’t have any trouble doing that as you will find this site pretty interesting as I did. You will wind up asking questions and commenting  on some of the posts maybe helping out the next guy with there problem or just posting some cool pics etc. 

So welcome to Quadcrazy and enjoy the bike brother!

      Has anyone had a suzuki 230 quad lock the engine up?
      By docdoug72
      Has anyone had a suzuki 230 quad lock the engine up?  Its a well maintained bike, it locked up when my son was riding it. Pulled the plug, it has connected with the piston. I'm thinking the con rod let go.  I don't have a service manual.  Does the engine need to come out to check further?

      1989 Moto 4 YFM350ERW intermittent spark.
      By RGS
      1989 Moto 4 YFM350ERW intermittent spark.
      Quad has set for about 7 years and was running when parked.  When I replaced the battery and attempted to start it had no spark. 
       
      What I have done.  Followed troubleshooting in the manual. 
      1.       Coil failed the resistance check so I replaced it.  Still no spark.
      2.       I performed resistance checks on the stator and they all pass.
      3.       Found a bad rear brake stop switch and unplugged it and connected the wires in order to disable.  Now I have intermittent spark.  I believe that the issue is with either the stator or CDI and not sure which.
      1989 seems to be a transition year for electrical.  I can get new aftermarket CDI units for 87-88 and 90-94.  I cannot get ones for a 89.  I can get new stators for 87-89 and 90-95.  Looking at the schematics the wiring on my moto is closer to the 90 ones on the ATV side of the CDI and closer to the 87-88 on the stator side of the CDI.  Looking at part supply sources the stator housing is the same part # for all the years and looking at some of the stators on Amazon that have the dimensions on them both of the stators are the same size.
      What I am thinking of doing is to replace the stator and CDI with a 90-95 one as these parts are all readily available.   Does anyone know if this has been tried before and if there are any issues with doing this.  
       As a side note I also have a 1993 Moto 4 YFM350ER that has been sitting longer but it is located about 400 miles from me at this time.  By doing this change in addition to being able to get parts I will also have 2 ATV’s that are the same electrically.

      Heavy Duty ATV Cover
      By Gwbarm
      Does anyone have a recommendation of a really Heavy Duty ATV cover. I have bought several and they do keep the water off somewhat, but they are very thin and do not contour with the shape very well and water pools up in the rack louvers. I think i may be looking for a heavy canvas one, if anyone has a recommendation it would be greatly appreciated.
