Bought a 88 big bear 350 4x4 took it for a run and lost spark, found it was stator so I replaced that then took it for a long run and it sat for 2 days and no spark again, this time stator tests good on ohms and voltage for source and pick up coils so I started replacing things including regulator, ignition, ignition coil and plug cap, spark plug and everything tests great including all safety switches until the orange wire for ignition coil from the cdi it only reads 3 volts so I replaced the cdi and still 3 volts, any ideas??

Fixing for a friend. Atv was at a different friends house to be fixed and he rebuilt the carb and had it running nice, then it shut off and no more. He replaced the key and the coil.
So he got busy, so I am helping, I checked the wiring from the stator to the cdi, and from the cdi to the coil. All is good. I checked resistance on the pickup coil, good, and on the source coil, open. I buy a new stator (China) and the 4 prong plug only has 3 wires in it while mine has all 4. I checked resistance in the source coil and it's in the 300's. I pulled one of the old pickup wires out of the old stator and wire it in the new one. Still no spark.
Why do the wires differ, I checked the VIN again and it's "J" for the year and I got a 1988 stator. Please help!

Hello
My son scored a free Moto4 - late 80s from the looks of it. I don't know anything else about its history as the owner wasn't there when i picked it up. Can't see the VIN number as its a bit rusty. He cleaned the carb and then with some either it started and still starts first pull. Its runs really nice - not rattles etc. Goes forwards well and the brakes work fine so it looks like a keeper, However, we have only managed to get it into reverse once.
1) it won't shift down into what seems like where first would be - 2nd and upwards only. The changes between gears is fine. No crunching or missed gears - just no first gear. 2nd gears appears to be as low as it will go
2) the clutch - when you hold the gear lever up or down works (only the second ATV we have had. Other is a Quadrunner which doesn't have this feature)
3) no neutral light - will start when no in neutral - should it do that?
4) the one time we did get it into reverse the neutral and then the red (reverse) lights worked. Swapped easy between forward and reverse - when it went into second, it didn't return to first or neutral
5) checked the clutch adjust on the RHS - seemed fine to me. When i turned the screw back 1/8 it was where it was to start with. Clutch doesn't slip. The bike will move forward is all gears.
Any help would be appreciated
Thanks
Andrew

I have a 1997 Yamaha Big Bear 350 4x4. It used to start right up. Then all of a sudden it wouldn't crank. I have a schematic for it so I started tracing the problem. I had no power at the starter solenoid. According to the schematic the power comes from the neutral switch and through the starter circuit cut out relay. I cannot locate the cut out relay on this machine.. If I apply power to the relay it will crank with the start button.
The neutral switch is hard to get to with all the brackets on this thing. I did find out from all my research that if I apply the rear brake lever it will start.
Does anybody know if the cut out relay exists and where it might be found?

Hello there
I'm having a problem finding a quality carburetor for a 1993 Suzuki Quad Runner lt-f 250 2x4. I find a lot that have 3-4 star ratings. And all so far don't have the right throttle Cable inlet at the top. The last one I got 4 star on Amazon has a threaded cable sheath rest that could be partially drilled to work. I would prefer to get one I don't have to modify. Any recommendations are greatly appreciated!
