RMSTATORTested PeakRPM CDI Box ECM Replacement For Yamaha YFM 400 Kodiak 2000 2001 | OEM Repl.# 5GH-85540-10-00

Wow! Super impressed with this company and product. First off this was for my 2000 Yamaha Kodiak 400 4x4. I had lost spark just randomly one day after I shut it off. Had replaced the stator and pickup coil due to frayed wires and age in hopes it would fix problems but still no spark. Bought a cheap $30 CDI on Amazon and it was wrong one. Finally pulled the trigger and got this one as Yamaha wanted $450 for new one.Package came nicely packaged to prevent damage in shipping. RMStator also sent packet of dielectric grease for the electric connectors, decal sticker, keychain, and coupon for future purchases from them.This is a 6 pin and 8 pin electric connector. Installed and ATV fired right up!! Easier then ever before and sounded better then it ever had. Very happy and pleased THANK YOU!!

This CDI box worked perfectly,My 2000 Yamaha Kodiak 400 would not start for me one day and I could not figure out why. I had the carb cleaned, new spark plug, New Coil, New Stator and still nothing. It turned over (not very well) and I could get spark with my spark detector if I went straight from the Spark Plug Cap to the block. But as soon as I put the plug in I had nothing. I bought the $70 CDI box thinking I would save the money and they are all the same. Plugged it in and it would not even turn over any more. So I ordered this one. Once I plugged it in my machine fired right up better and faster than ever before. Save yourself the time and DON'T BUY THE CHEAPER VERSIONS!!!

This 4wheeler has been the death of me! Stator and CDI box both went out. Yes, I went the cheap road and bought the cheaper CDI box... waste of time and money! Don't make my mistake... but this one first, and save yourself the headache. (btw... it comes with a sticker and a keychain! I love stickers... ) LOL

I purchased the high performance box on June 5th, 2020. It arrived ahead of schedule and the part worked like a champ when I first installed. It lasted until last week and died. This is on a work 4 wheeler and has been used maybe 7-8 times since install. When I try to crank the the 4 wheeler I can hear the CDI making short sound.

Perfect dropin on Kodiak 400, 2000, with noticable increase in acceleration. Did not test top end as ATV is too fast already.

Bought a cheap CDI and motor wouldn’t even try to turn over. Spent the money on this one and spark came back to the ATV and started right up.

Worked perfect in 2000 Yamaha kodiak ultramatic 4x4!

So far....so good.Seems to work as well as original....at a lower price.

Avant de commander ce module cdi, j'avais acheté un autre module cheap à 70$ qui n'a jamais fonctionné!! Celui ci a marché du premier coup! Je recommande!

Fast shipping and does exactly what is supposed to do at a fraction of the cost of the OEM part! Excellent service; great company to deal with.

perfect

This has brought new life to an 20 yr old machine. Can't believe the improvement.

Exactly as described. Quick delivery. Great product. Worked right away!
