The TImberWolf looks really fun, and is actually in great shape. I got it to spin over with a jump So that's a good start. Needs some tires and tlc but gonna be a quick one for sure. Takes a lot of cleaning, usually pull everything apart and go from there but they usually clean up nice. I pick them up off craigslist or facebook. Most are way over priced. I limit myself usually to 350 max apiece. Az

little on the high side, 650 for both. But ill probably get it back out of them later. Looking at the Bayou see anything wrong lol, has the pos grounded! Pos wire is broken in half. .

Went shopping on Saturday, picked up another Kawasaki Bayou 220 and a Yamaha Timber Wolf 250 I really should sell some of these but they are a lot of fun to find, fix and ride Of course neither of them run but that's part of the fun! Az

All done for now a few pics, one other thing. It actually had the original tool kit in the trunk. LOL

Gonna have to look at it again. Thanks Az

I had the same problem, ended up replacing a blown fuse and the ign. switch

Well got home from work and decided to look at it again. Adjusted brakes where they used to be (back brakes) and now shifts into reverse! WTH? Did a little experimenting. Use front brakes only and try to shift into reverse = no go Use rear brake only (Right Foot Pedal) push far down and it goes into reverse! Now the rear foot brake lever doesn't trip the brake switch as light never comes on so its not solenoid operated and don't see anything but a cable but I guess ill never understand that one. I saw in the download on adjusting the shift lever and they talked about the brakes but really didn't make sense to me. Guess it does effect them somehow. Put that in your note book. Any way im off again, when im finished with it I will post some pics. That thing will burn some tires though lol. Az

as far as I know you just make sure its in neutral and then pull the lever from Low/High/Reverse. oil is full, it worked perfect the first time. I did adjust brakes but don't see how that would affect it. Then again I could be wrong but don't see how that's tied in to a cable going to the motor, also tried it with engine off. Any Yamaha experts out here? Az

Got it back together today and took for a ride. Runs good only problem the reverse shift. Shifted from low to high and worked fine, shifted to reverse worked fine. After that wont go back to Reverse and don't want to force it. I can see the lever on the motor trying to move when moving shifter so cable should be ok, anyone have problems like this and what to do to resolve it? Az

Thanks for the diagram. My battery and meter both showed up today. Fired it up and got 20v on each of the 3 legs coming out of the stator. Checked voltage at battery and presto have about 14v What did I learn? Well make sure the battery is actually good before further diagnosis. I knew it was bad but figured I would still read charging voltage at it since it wasn't shorted, I was wrong. (2) Use the right tools, Im still using my old meter from when I worked on cars lol that has been before 2007 so meter was outdated and didn't read acv. Now to clean it up good and put all back together. Thanks for the help and hope this helps some one else with charging problems or just checking the charging system. Az

They look to be white, being as old as it is they could have once been yellow. second picture on the left is the connector

I get no voltage at stator wires when running but am using dc meter, ordered new meter that will read ac current so have to wait for that. has to be charging something for the batt voltage to go from zero to 7-8v when connected. Also disconnected stator plug/key off and ohmed term 1-2 1-3 and 2-3 all reading right about 1 ohms. Looks good to me so far. lol not gonna pull the cover until I get to check voltage with new meter and have new battery installed. Any one got any specs on this machine? looked at a 200 mot0 4 download but the charging system diagnosis was worthless. Az

I meant a 1989 Yamaha Moto 4 350 Thx

Looking for a repair manual for a 1995 Yamaha Moto 4 350 Thx

Update. Okay got carb fixed, started it up, runs pretty good. Decided to check charging voltage. At battery only have between 7-8 volts while running, idle and above 4K no change. Disconnected Neg. side of battery while running still runs same. Reconnect battery and unplug voltage regulator and voltage goes to zero. Plug back in goes to 7-8v Disconnect at connector at stator and voltage at battery goes to zero. Plug back in and goes back to 7-8v Main fuse is good. My meter wont check alternating voltage but I am assuming the stator is bad. I checked each stator wire to ground and no continuity which is good. Now my battery is bad and wont hold a charge, but I would still assume I would get charging voltage at the battery. Should I wait to replace battery and recheck or is the stator bad? From the stator harness what are the other wires, (yellow,blue,green,) neutral safety switch? red and white I figure are pick up coil, the 3 other white wires I assume are the charging wires those are the ones I checked.

Yes I got the year code, its a 1989 its just weird they are saying problem with the 9th digit where you really cant confuse that number with any other. No couldn't get the carb off that way but finally tore it all apart and got the carb off that way. Needed cleaning anyway. I always tear them down wearing gloves and with a can of raid. Everyone I have taken apart have had pissed off black widows living in them. The same on this one. Got one under the gas tank! Anyway took the carb apart and didn't see anything in it to make it flood. Float looks good, not full of gas. Needle is good no ring and nothing under the needle that I could see. Gonna clean it up and see if it still floods. if it does ill get a carb kit. Az

Cleaned up pretty nice, tires good, the more I check the more I like it. Oil is clean, air filter new. plug is rich fouled but new and they said gas was leaking out of the carb so hopefully something under the needle. Getting the carb off is going to be a pain. cant get to the cables under the tank without pulling off the tank, in order to pull off the tank you have to pull off the front fenders and to pull them off you have to pull off the handle bars and all the components attached to the bars, Battery is dead and no good but I think this one will turn out fine. It also included a pull along home made heavy duty trailer. Dam thing probably weighed 500 lbs. kinda cool as it has airplane tires on it. Not bad for 350.00 Well it gives me something to do and keeps me busy. Az

And once again picked up a dead atv. This time is a Yamaha Moto 4 They don't know anything about it. I cleaned up vin best as possible and everytime I run it it says 9th digit is wrong. The vin I punch in is ( JY43HPW08K0000690) So I think its a 1989 and on the side of the motor is a 349 cc on cylinder so I assume its a 350 correct me if im wrong. its been dead for about a year. Any info would be great to what it is for sure and if maybe there is a manual here for download. 2wd, oil cooled, elect start only and batt is dead of course. Post couple of pics Thanks in advance Az

LOL, After further checking its not running rich, its blowing oil. With the compression being pretty good im assuming its the valve seals. Little more than I wanted to mess with as everything needs work. Just not worth the effort for what I got in it. I posted it for sale at double what I paid for it and have at least 20 offers. Hoping just to let it go tonight. Looking at it its pretty rough. Some pics for your enjoyment lol. Az

Thanks Az

So im back at it again. Another headache but different manufacturer. I picked up an 81 ATC 110 for almost nothing. It is nothing to look at but they seem to collect them out this way so I figured I could always get my money back no matter what the condition. The motor wasn't locked up and it had spark. Had not run in years (always the case) I pulled off the carb and cleaned it out the best I could, lots of corrosion. Years of water etc. after pulling it forever got it to fire but would barely idle and super rich off idle. Black smoke fouling out plug immediately. Ordered a (yes you guessed it a Chinese carb as only available) and still super rich, same no change. Choke is open. I lowered the metering rod as low as the adjustment goes. Turned in the a/f screw and bottomed it out still rich. Not flooding, float level good and nothing restricting air flow, air box is not there just open carb. I ended up checking compression and only had about 75psi I checked the valves and the exhaust valve was too tight. Loosened it up and got 110 PSI Now starts easier but still super rich. Black smoke when you rev it up if it revs up cant find any other way to lean it out. Have another carb on the way but not very confident it will fix it. Any weird things to look for? Checked cam timing its good. It has elect. ignition and even tried to advance the ign. timing just to see what would do. So what do the ATC Masters have to say? Pics to follow. Az

Well I contacted the seller of the defective carburetor and they sent me another one. This one works great, tons of power, not lean at idle or off idle, idles great and starts great. Couple of pics of my 100 dollar atv after all the headaches. I love a challenge. Next is a 81 Honda ATC its the worst I have seen. anyway enjoy

Yea I thought it was a good buy, had to drive about 70 miles one way to get it but still worth it. I used a cheap carb on the bayou 220 and worked fine but this one is like it was too small of a cfm. didn't seem lean as mixture went but was just too small. Like putting a 1 barrel on a blower set up. Just have to put all back together now and hope all the bolts are in the bucket I got along with the other parts with it.

Update. Ok after re adjusting valves this morning and tearing everything down again I decided to get the original carb which was originally full of dirt and sand inside and went through it again, same as last time, compressed air, carb cleaner through all the jets, air bleeds etc. put that one back on the engine and fired it up and presto, like magic all power there, no more backfiring at idle, reved up great, drove it around and runs almost like new. must be a combination of valve timing, valve adjustments, carb problems all in one to finally fix it. I now agree with most everyone else that the Chinese carburetors are junk. Mimicked other problems, don't know if jets are too small or what, wasn't lean at all. Now the the last thing. I runs great but at an idle its about 300 rpms lean. I tried adjusting the needle at the bottom of the carb while running and no change. How can I richen it up at idle only and not off idle? There are no adjustments on the needle on the diaphragm. Float is fine, If I can fix that lean at idle it will be like new and I might have some hair left lol Thx. Az
