Was scared that my stator or something electrical was wrong. Turned out it was my vid box. This fixed it and now ripping again !

Fixed my problem, bike was dead no crank. Bike would crank in reverse but not in forward. Swapped out with this Cdi and now it cranks and the engine performs a lot better than before.

Made my Yamaha run like a cheetah on cocaine

My previous CDI was working, but it was getting old and ready for a new one. So I order this one for my 97' Yahama Warrior 350. As you know, this one is easy to swap, unplug old, plug in new one. I did that, and it absolutely did not work lol. It was firing the piston before it was ready to start up, resulting in some HORRIBLE noises. I unplugged it, plugged old one back in, and was back to normal when starting. So I know for a fact this CDI is junk all together, or it doesn't have the correct internal wiring for a 97'. Plugs fit though, but doesn't actually work right. So I guess whatever year Warrior you have, if it doesn't sound right, it's not you or the quad, it's the CDI lol.

Did not fit my year warrior. Check your connectors twice. I ordered the wrong cdi only one plugged worked. I ended up ordering a different one. Seems to be good quality

Yes, this new CDI makes the difference

Good
