1986 yamaha moto 4 200 rebuild

Recommended Posts



The best way to find that out is to look up the part number for the cylinder for each bike and see if the number is the same.  

I looked up the part number for the 200 and 225 and it was the same so it could work. But keep in mind that all shit rolls downhill when you upsize it’s re-jet for the carburetor, exhaust may be tight with too much back pressure, so you can’t just go with a bigger piston and think your going to be ok.  I would prob go the route of boring the existing cylinder and re-jet the carburetor in accordance with the bore and piston size.  As far as exhaust goes after that it would be a matter of changing the silencer/baffle.

      I recently got a 98 warrior 350 that 'needed the carb adjusted' but the reality is it has no spark. I have a new spark plug, plug wire, ignition coil, battery, and cdi box. I checked continuity and took apart and inspected the starter/kill/light switch on the handle bar, and it all looks brand new and checked out. The key switch seems to be working properly, as when off, nothing works, but when switched on, lights and electric starter button work. It turns over fine, and as I just stated, all the lights work. I took all the plastics off and traced all the wires, and only one had a small cut in it, but it was only through the rubber sheathing, not the wire itself (the blue one coming from the stator). I cleaned some grounds, made sure both relays work, and still nothing. I pulled the stator cover and looked at the stator itself, and it looks great. No broken wires or connectors or anything. Still, no spark. I'm at a loss. Where do I go next? Any help is appreciated.

      I have a Yamaha 350 in at once to try to fire up but won't. It's getting gas fire air and it has a lot of compression but still struggles to start check the timing it's top dead center valves are good valves are adjusted everything's working but won't fire I put my hand over the carb suck in gas and it tries to but it makes a lot of black smoke. Also when I put my hand over do you carb and tried to start it there's black black nasty stuff in the gas. So I don't know if it's trying to burn too much or what it is the gas tank clean and it anything to do with the gas it's with it firing. Took the spark plug out and it's pure black. What is dried up black not nasty corroded wet looking. Need help to solve the issue

      Truck, Trailer, TWO 2008 YFZ450 ATVs, and 1000s in tools and equipment took off from the Valets parking garage for the hotel.
      The truck and trailer were left abandoned 3.5 miles away in an alley empty of everything on Caldwell Street near Owenwood.

      I have a Yamaha Warrior 350 in the cam sprocket won't line up with the cam mark on the top end on it. I advanced it Forward 1 tooth and reverse it one tooth. Tries to start but won't. And of course I did the T on the flywheel for top center and it still won't line up.. need help trying to figure out the problem.

      Our 1988 Yamaha Terra Pro is finally seeing the finish line of becoming our new bush hogging tractor! I've had the terra pro for almost 2 years... we had great intentions, but after removing the fenders, fuel tank, and the carb, we let it sit up. Shame on us! However, the terra pro is cranking today. We cleaned the carb, figured out what goes where and where did that screw go! She smokes like there's no tomorrow, but that's okay! The only issue right now is getting all these lines hooked back up to the carb right! There is 5 lines to hook up to this thing!! And in our moment of drinking and removing parts, we cant remember how they go back on. I've found several diagrams online, but none showing the overall schematics of all the lines! If anyone has a service manual, or any way of helping us figure out what goes where I would really appreciate it!! I can attach pictures later if it'll help!
