Man that’s a tough gremlin you got going on. So the only few things that could be doing this then is a short within the wiring maybe along the frame ? Could be a bad connection on one of the plugs even the single pin and sleeve plugs that are all over the harness. Maybe take them apart, clean up and add some dialectic grease and reconnect. Check to see that your ignition switch is ok, I’ve seen some people find that wiggling the switch allowed the bike to fire up due to poor contacts within the switch that sends voltage to the cdi. Some only have two wires, a brown and white, if so then it’s good if your getting dash lights but check thats your model. You tested continuity on the kill switch that it’s opening and closing yes ? You checked continuity from each phase of the stator to ground yes ? (Should get no continuity) Main fuse on the starter relay? Im just throwing random sh** out there and trying to jog my memory from my bayou.

I was just looking at the manual and that does seem weird that it just slides off. Are there any bolts/brackets missing on the swing arm or any bushingS that seem not right ? There should be a constant pressure holding all that together. The bayou is a little different and locks in with all four of the bolt you see on the bevel gear housing case. I would definitely inspect every bushing and bolt back there and make sure everything is tight. How do the universal joints look and feel ? You could spray it good with a cleaner and add a drop of silicone then slide it back in and let it dry. Maybe that will stop if from sliding out. My last guess is that the seal itself has worn down from rotation and has gotten shorter which means replacement.

I’m sorry I thought you took it apart and screwed the nuts on for safe keeping. So that drive shaft pops on and what holds it in place? It looks different from the previous pic you posted. A lot dirtier lol. So you unbolted the swing arm and backed it off ? I have only taken the bayous apart and they are very similar so forgive me for being a little confused. Post a few more pics if you can.

I wouldn’t focus on the irregularities of the spinning readings. The coil is supposed to be tested while it’s not spinning and away from the magnet. It has to be on ohms and you should get pretty much the same number every time you test it. If it’s within spec it’s good. Then the same tests should be done on each phase of the stator coil wires. Between phases (wires) and then from each phase to ground for continuity. If all that comes back good then it’s something else.

Maybe onto something, reach out to Gatorade maybe pitch it to them ! 😂 I can see all the athletes jumping in Gatorade sausage lmao. Going to have a lot of pissed off Italians lol.

So it could be a bad pick up coil if the numbers aren’t good. But without the flywheel spinning and the magnet not near the pick up coil do you get an ohms reading on the two wires ?

Good stuff right there. Fire starring skills on point. Gatorade and sausages .... not so much lol. But that place looks like a blast to ride. Where do you find these places ?

Nice work. That black seal is the O ring. It’s probably crushed a bit and that’s why it leaked. Obviously your changing the boot since it has holes in it correct? Get some carb cleaner spray and spray it on that dirt and wipe it clean. pop in the new O ring seal then add a drop of grease on the splines before you put it back together and your good to go. Just make sure you tighten the four nuts in a crisscross configuration so it seats evenly, I like to put a drop of lock tight on the threads.

Have you checked the regulator/rectifier?

Sorry it took so long I’m up hunting and it’s hard to get a good signal up here and the time to look. Attached is a page for the ranges of all the coils etc. Also all the diagrams I could find. It’s about 6 of them and because you don’t know exactly what bike it is yours is then your going to have to compare each diagram until you find a match. Can you see the vin number clearly ? If so then post it. Maybe we can find out more.

If it’s new it should be fine. What you should get is a reading on ohms setting, if not then there is a problem. I am looking at diagrams for you. I will be in touch.

Ok I’m looking now

it will be fine. Just need to figure out what diagram fits your atv. Can you post sole pics of the cdi and the ignition. Make sure there aren’t any wires that your not seeing that may be disconnected?

This is the US diagram. Sorry about that mix up. You might have them wrong cdi if that’s what you purchased or that atv is the Europe model which I doubt.

I just realized that diagram is the Europe model. Hang on a sec

Here’s the diagram

That grey wire goes from the cdi to the ignition switch.

No worries, that’s what we are here for! keep us posted.

Welcome to Quadcrazy! My guess is third gear is probably shot. Unless the shifter is blocked by something I would assume it’s an internal problem. This would only be corrected by pulling the engine and splitting it open. As far as any mods/new engines I would probably stay with my existing engine and just repair it. If this type of repair is beyond your capabilities then send the engine out to be repaired.

Good stuff.

Pressure washer ! Small one like we spoke about a week or so ago.

Only thing I can think of on the simple side would be a dirty carburetor or stuck choke, maybe poor fuel delivery from the tank. Second thing would be electrical. The spark could be breaking down so it could be a bad rectifier or ignition coil, maybe water inside the kill switch or ignition switch, a break in the wire harness maybe where you have an intermittent short. You can do some easy testing on some of the electrical parts other then the cdi. lastly I would check the timing to make sure it hasn’t jumped a tooth or two on the cam sprocket. Based on the backfiring it’s a symptom of timing but hit the simple stuff first before you start digging deep. Honestly and I don’t want to sound repetitive we have had members here that swore the gas was fine and the plug was good and after a second look it turned out to be just that. Hopefully this helps you out.

$34 is a great price and it’s a direct fit. I added one to my rancher last year. The previous owner left a cigar on the seat and it burnt the cover. My older project bikes I like to make myself.

Agreed with @Ajmboy could be a foiled plug or a dirty carburetor as well as bad gas.

Good stuff brother. Nice work, try and stay away from them branches. Ride safe and good luck hunting this year. Be sure to post some pics.
