    Good work Gw, Did you weld the extended foot rests, or the previous owner? I'm thinking of doing something similar to my quad. The reason is because stock setup does not have much of a foot rest.

    Thanks for all the feedback! Here's how the original CDI got blown: After riding several minutes the ATV suddenly stopped and quit running. I quickly found that the positive terminal on the battery broke off while riding from all the vibration of 20 years. (The engine was not running at this point) After wedging it back on, the quad started up & ran fine, but due to the bumpy road the cable kept coming off, the engine dying each time. After doing this three times the 4 wheeler would only turn over, and as it turned out, it lost spark because the CDI got blown.

    Hello everyone, it's been a while since I was here last. I finally found the correct used CDI on eBay for $315. After plugging it in, the 4-wheeler runs good again. Success! The only thing I don't understand is why the original CDI got burnt by connecting the battery terminal back 3 times while it was on. You would think it would blow a fuse first!

    In my case, the CDI clearly got fried. Still looking for a replacement, any info on where to find a slightly cheaper one?

    I'll try repairing the CDI. If that does not work, looks like my only option is to buy a overpriced new one.

    1 Hour of chipping away, and my first gimps of the circuit board. it would be ten times faster without all those mixed in white plastic bits.

    I already tried one of those aftermarket CDIs with no luck.

    4x4, The CDI should have 2 plugs: 1 with 6 pins, and the 2nd with 8 pins.

    Keep us posted if the CDI works.

    One of the connectors is slightly different on mine, so it's not compatible with my quad. Also one of the reviews says: 1.0 out of 5 stars Did not work for Yamaha big bear or wolverine 350 Reviewed in the United States 🇺🇸 on March 5, 2021 Verified Purchase Came on time but item does not work! I have a 98 Yamaha wolverine 350, and a 2000 Yamaha big bear 350, I tried on both and didn’t work.

    Ok.

    Thanks for the help guys. I'll try repairing my OEM burnt CDI, if that does not work, I will halve buy a new OEM one.

    Would a Kodiak 400 CDI work on a Big Bear 400? The connectors seem to be the same.

    Regular synthetic Mobile-1. Works well in all small engines.
  15. QuadMan49
    The photo makes it look like melted plastic but it's not. I removed some silicone/plastic material with a tool.
  16. QuadMan49
    I use Mobile-1 10w-30 synthetic oil from Walmart in my equipment. It's $60 for a 12qt cardboard container, 10-40w is the same price.

    That is, if I can ever get the CDI fixed.
  18. QuadMan49
    Should I try some rubbing alcohol, or nail polish remover? Not sure if they will damage the circuit board.
  19. QuadMan49
    Welcome! I've joined pretty recently as well.
  20. QuadMan49
    Thanks everyone! I'm in the process of chipping away at the silicone rubber stuff from the CDI, and it does smell like burnt electronics.

    To clarify, I bought my quad a year ago in excellent running condition. About a month ago the 4-wheeler bogged down while riding, I quickly discovered the positive battery terminal snapped off while riding. As soon as I put it back on temporarily, there was a spark and the quad would not run anymore. I looked at the CDI and several capacitors were popped out. I tried a $25 aftermarket CDI, and not surprisingly it wouldn't even turn over. With the original CDI it would turn the motor .
  22. QuadMan49
    Does that mean I'm stuck buying a $300 one?
  23. QuadMan49
    Hello, Long story short, I accidentally fried my quad's CDI box. I found several OEM ones for $300 which are out of my price range. Does any one know where to find one for less? Or any way to modify a $20 Chinese CDI to make it work? Thanks.
