Help on a "yamaha 350" wiring.


Recommended Posts

I posted a bigbear pdf of the wiring diagram and it has the right colours, or the same colours without stripes.. It shows which pin on the cdi goes where so you can wire it to suit that I think.

The different models have at least three different stator winding systems that I know of, and all three types come with different wire colours, plugs, and internal connections. If your wires and plugs match, it's likely that you will have comparable stator and cdi.

The pdf also has the stator resistance readings.

The biggest problem there is, if this is a wiring harness is for the Big Bear 400 there is no aftermarket CDI available, ask me how i know. It is still very doable, you just might have to do what the guy on the video did. The other option is find the right harness for the warrior, from Mechs reasearch, it doesnt sound like you got a harness for a warrior. Study the  warriors harness so you will know what it looks like if you go that route. I dont see how you can figure out how to wire the CDI you bought unless there is a schematic as to how it is wired internally. Mech might have more options right now thats all i can think of.

Well thats about shitty haha. Wonder why this stuff is being sold as warrior parts then. Makes no sense. Appreciate your input.

So.. I noticed the BB diagram I'd posted had the wrong plugs.. Dunno what happened there.

After much searching I've found several BB diagrams with  the right six and eight pin plugs. Wrong coloured wires, and that #16 off to the right of the cdi, it's a speed sensor ! Bet yours hasn't got that. Anyway. Have a look and see if the wiring seems like any of these. I've included one complete wiring diagram so you can see what all the other bits are. The brake and front/park brake wires going to #10 and #12 aren't really needed as long as you have the neutral switch connected. #10 and #12 allow it to start in gear as long as a brake is on. The bits highlighted in white are the essential bits for it to run and kill.

It seems the warrior cdi, with pigtails, has a lot different stator windings than the Bigbear with the plugged cdi.. Different design and different resistances.

Better check what the stator's cdi charge windings and cdi pulse.trigger windings are..

Could you elaborate? How would I go about that. Like from a picture?

Try to figure out what year the engine is, I saw a wiring harness with pigtails on eBay it is for a 90-95 warrior they also had the pig tail CDI that goes with it . So I’m thinking your engine is somewhere in that range

Probably was in that range originally. I have no idea though, as one half of the case is the one from the buggy that i bought. The other came from a kid I traded a 3ds to he had a warrior that threw a rod bearing, but i just needed the top end and the case half with the oil drain as that had been mangled. Internals were from whichever looked better, but they were all the same. The stator was purchased on ebay and said that same 97-01 in the listing. The plugs match what are on the harness.

Yes that makes sence,  if the stator is from a newer warrior, as far as i can tell the newer ones did have an 8 and 6 pin CDI connector. I tryed looking up the newer warrior OEM part but it only showed a CDI at an angle that you couldnt see the pin configuration. I revisited your ebay purchase and it does seem right for the 97-2001 warrior, didnt see a link for the harness you bought but if it plugs in it may be compatable. I dont see warriors very much, but it appears the later years went to the 8 and 6 pin configuration just like the big bear 400, i have never seen a 350 with that confuguration. Just reviewing everything I would have bought exactly what you bought thinking it might work. Working on a project like this there are so many variables to over come, i love it, its like putting a puzzel together, may not be worth the time and effort you spent but when you are finished it works, and you are proud of your accomplishment.

To check the resistance readings you use an multimeter on the ohms setting. You just set the gauge to the right ohms range then put the two gauge leads to the two wires on each plug and note what the gauge says.

Those last pdf say the kodiak did have that eight/six plug setup.. And if the advertisers of the cdi say it fits warrior and kodiak of similar years, then perhaps it will work.

All the warrior diagrams I've seen have said they had pigtails, but that might be because they were for the American market. It could be that some other country used the cdi you have, or perhaps it's only the CA models.. The parts books say it's only the CA that has that cdi. 

I wouldn't recommend rushing off buying more parts yet. I'd figure what stator was in that bike first. There are two obviously different stators, one model has a series of windings all the same size, and another model has several all the same size and one big winding. Do you remember, or do you have an old one you can show us ? If you don't have a multimeter you should get one, and check the resistance readings. I'd recommend you buy an analog gauge, that's one with a needle. They are getting harder to find but they are more useful for checking pulse/trigger windings, and plenty accurate enough for bike work. Cheap analogue gauges here in N.Z are sometimes as little as $10 N.Z.

      The studs in the sprocket hub are stripped out. The hub is probably walloed out also. Probably will have to have a new sprocket hub. I doubt I have the ability nor the tools needed for this job. Thanks for all suggestions/opinions!

      So I decided to pick up a small trailer if I could get one for the right price.  I found this one for a few hundred bucks on Craig’s list.  It is  a galvanized trailer which is exactly what I was looking for. The wood was shot and needed some minor repairs which I could care less about as long as the chassis was good. 
      I striped it down and put a new deck on. I had some vinyl realtree graphics that I had laying around so I added them to the fenders which I think worked out well. Very happy with this little guy.  
      I'm having the iron workers at my jobmake me up a few lightweight side rails that will have a 22 degree bend in them to accommodate the tires that slightly hang over the edge and will incorporate some tie down points as well.

      I have been rebuilding some ATVs in my spare time and teaching myself along with the help from the internet how an engine works and getting bikes running again is quite enjoyable. I even built an arctic cat 300 4x4 from two parts bikes the had seized motors and missing parts. It was pretty enjoyable. 
       
      So I am now working on a sazuki quadrunner 300 1992 which had a whole list of issues when I got it. I have fixed almost everything I need to in order to get this bike running. But something is going on inside the head or crankcase. 
      I had to replace the timing chain because it was very stretched due to the previous owner.
       
      What the issue was, the timing chain was off the sprocket inside the engine due to it being stretched it slipped off. So the previous owner rebuilt the top end thinking it would fix it which it may have temporarily, but when doing so they welded an extra inch onto the tensioner to hold the chain tight. Which as you can imagine caused a dozen other issues.
      So that stretched the chain to the point where I could remove the cam with the tensioner in.
      It beat the sliders all to hell. Destroyed the cylinder housing and obviously ruined the tensioner. 
      I didn't realise all of this until after I rebuilt the engine.  I noticed wear where the timing chain runs through the cylinder. I found the cam had no retaining chair, or clip whatever you want to call it so the cam was beat to sh** also. It had almost an inch of play side to side.
      So I pulled the head off of my parts bike and fixed all of it. Then put it together and went to pull it over and found it was not on the sprocket (this is when I realised that all that damage and the welded tensioner was because the timing chain had been off the sprocket) 
      So I pulled the stator cover off and pulled the flywheel (which I should add to get at the stator cover I have to remove the rear tire and a arm as well as remove the bolt through the front of the engine. And the exhaust system has to be removed to pull the cylinder as the exhaust guard is bolted to the side of the timing chain tensioner. Stupid setup. Glad the king quad doesn't have that. 
      So I got everything apart and the flywheel off. New timing chain (nice and tight now) put the head back together and flywheel but it is quite hard to turn the engine over. I can but with difficulty. When the valve cover was off it seemed to spin much more freely. Before I tear everything back apart and start again any ideas on what it is?

      Im finishing up on the Big Bear, just tying up some loose ends and its done.
      My next project I actually bought first, but the Big Bear seemed like it was more challenging so tackled it first. Now looking the Eiger over im not so Sure.
      I bought this Suzuki Eiger, almost a year ago, rear wheels locked up, but it ran fairly well. It was so bad that it took 3 Big Guys to get it on my trailer. All the parts were there it ran. He wanted 600.00 and I offered him 400.00. a plus it had the original Kei Hin carb on it.
       
       

       

      You might ask, why would you want something so ugly, it is often referred to as the ugly sister to the King Quad. I actually like the Eiger I have this one and also a 2007. I have riden them before, they are strong a true beast, I am a fairly Big Guy 6' 3" 195 pds, and it fits me good, but what I really like is the wide foot print and low center of gravity , not so easy to turn over.
      So I get it home and I don't have 3 big guys to help me get it off my trailer, but I do have a John Deere, hooked it up and drug it off the trailer,an afterthought I should have used a couple of furniture moving dolly's under the rear wheels, oh well. Maybe I didn't ruin the already stuck rear end or transmission I was sure which, I was fairly sure it wasn't locked brake drums, after all that they should have popped free.
       This is what I have done so far. It's off the trailer I took the drive shaft bolts loose, they were tight, had to get a 3 foot cheater, I thought they were going to break. Got them out and now I can roll it around. I checked the shifter, this is a manual shift Eiger LTF400F. Foot shifter moved didn't seem to be going to any gear, but it was hard to tell, the shifter on the tank which has Low, High, and Reverse did not move. I took it apart and oiled it up good still wouldn't move. Thought the cable was stuck so I unhooked it from the linkage and cable moved freely. Looked at the linkage closely and it was stuck. I tapped it lightly, very lightly , with small hammer and it freed up kind of, but still stiff. I could tell this side cover had been off before and put back very sloppily. This is kind of where i left off except the plastics are all off, you might have seen me working on them in another post. Nothing I have done so far has helped, my next step was to take the side cover off the engine to see what's going on in there, but installing my Granite counter top, numerous honeydews, and the big bear kind of slowed down my progress. I did determine that it wasn't the rear end, that's actually what I thought it was going to be. If anyone has any ideas, they would be appreciated.
