2005 Yamaha Raptor 660R not revving up SOLVED

- This 2005 Yamaha raptor would not rev up. I thought for sure it was the carburetor because it kept falling on its face when you hit the throttle.
I read several threads about the CDI box issues. DO NOT BUY A CDI BIX ON AMAZON! I first found a broken connector and thought that was the problem and realized I did not have the green and yellow wire that was for the reverse cut out. I ordered a replacement CDI box for $36 on Amazon which was made in China and when I installed it it did not even start correctly at all. The starter and spark were different. I also suspected the coil for the spark plug and replace that as well.
Replacing the CDI box and ignition coil did not fix the problem. After looking closer I found the black wire on the eight pin connector to the CDI box was separated. I also realized someone had already cut all of the Warriors on these connectors and re-connected them. I spliced and forced the black wire into its original eight pin connection location and the four wheeler started up but it still had issues. I then added a ground from the Green and white wire on the four pin connector. With these two corrections the Yamaha raptor 660 R is now able to throttle and I’m planning to test drive it today.
I was unable to find anyone that sells for eight pin connector or the four pin connector for the CDI boxes and I do not want to buy an entire wiring harness. Let me know if anyone knows someone that sells connector
Thank you so much for the information I grounded my CDI box and disconnected the switch by the clutch runs awesome thank you
Glad it worked for you. This was not a great video. I found the wire is also located under the left footpeg and can be disconnected there and grounded to the case too. Thank you for watching
That hose is your crankcase ventilation tube that hooks to the rubber snorkel on the airbox lid. You need to put a filter on the hose so you're not sucking up dirt & dust into your crankcase.
Thanks, this raptor was missing the air box lid, after I ordered one I noticed the boot to connect the hose. These 660 run much better on stock pipe and filter. I did replace the jets to a 145 on left and a 155 on the right and also a 25 for the pilot. It’s running great now.
Your video helped! Thank you
I am not sure if you read some of the comments but there is the same wire underneath the left foot peg. This wire is for the reverse sensor. If you ground this wire to the chassis it will also solve the issue
Thank you mine was doing the same thing
No shit...
Mine does the same thing & I was just checking that wire & I can see one just above the reverse switch. I will try unscrew the lug and see what happens.
Look under your left foot peg and there should be a warrior going to a switch. That is your reverse safety switch. Remove that one wire and ground it and that should solve the problem too. This will bypass your reverse safety switch so when you are in reverse, it allow the user to go full throttle so be careful. This is the rev safety switch that fails and causes the bike to think it is in reverse all of the time.
Another way to repair this issue is on the left side of the motor underneath the foot peg there is a green and white wire going to the reverse sensor. If you remove this wire and ground it to the chassis or the motor it will solve the issue.
How do you ground it to the chassis! Tap a small hole and screw it in?
Que funcion tiene exactamente la tubería que mete los gases del motor a la caja del filtro de aire¿ que sentido tiene meter gases a la admisión?
la caja controla el encendido y en reversa detiene las altas RPM del motor
So at the cdi box what color wires did you cut and ground? My 05 is having same problem
You can ground the wire under the left foot peg. Should be green and black. The sensor under the left foot peg is the reverse sensor. If it does not work the CDI thinks you are in reverse and cuts out power.
Just us a ring terminal connector on one of the engine screws
@@jakemir Thank you for this explenation, I just bought a 02 raptor for 1100 and it's doing this same thing
Mine does the same thing, but can I change the entire cdi box, would this help or this is not necessary?
It will not help. It is the reverse safety. Ground the reverse safety wire and it will fix the issue. Reverse safety is under the left footpeg and just needs to be grounded to the engine
How do i ground the green with white wire ? I don’t know anything about wiring lol
The engine or any metal part on the four wheeler is a good ground. A better way to do. It is look under the left foot peg and you’ll see the green and white wire there on a small switch. That is the reverse switch sensor. Remove that wire and connect it right to the engine by unscrewing one of the screws slightly and wrapping the way around it and tighten it.
So overall what did you to fix this issue because my Qaud is having the same problem?
Ground out the reverse sensor so the ECU knows it is not in reverse and activating the rev limiter. If you look under the left foot peg you will see a green and white wire on a sensor, found out that wire
Me podrías ayudar cual cable es exactamente x favor o como le puedo hacer
cable verde y negro debajo del reposapiés del lado derecho. tierra ese cable es seguridad inversa
@@jakemir gracias
Disculpa te podría contactar para mandarte un video de mi raptor y el problema.
@@carlosramos7360 buenas tardes usted arreglo el problema con tu raptor 660

Let me know if you need any help with it. You got a great deal. If it has an aftermarket pipe or intake you will have to jet the carb. I jetted mine about six times before I found the right combination. I would recommend staying with the stock intake and muffler but still jetting it. My 2005 660 was faster than my 2015 700 EFI raptor because of jetting it right
@@jakemir Ive got a Titanium 4 FMF exhaust on it, Where do you get your jets from? The person I got it from Has stock jetting still
So 1440/145 thanks by the way
Mine was jetted 145 left and 160 right. The pilot jet also need to be increased from a 22.5 to a 25. The local cycle shops will have them in stock, just bring in your old jets to match them up. Check out Geezer MOTO on CZcams. He has a video about it. I took off that carb so many times, I had it down to 30 minutes. DO NOT BUY THE CHINESE KNOCKOFF CARBS ON AMAZON. I made that mistake, they are complete junk and can’t be adjusted properly. Wasted about three days of my life.
@@jakemir I ended up getting a 6sigmajetting kit, if they dont give me 145/150/155 Mains in the kit ill take the d ones to the shop and just get them, I have 22.5 Pilots right now too, thank you so much, and you are at 145/165 mains right now?
Mine is doing the same thing I hate it
Did you fix it? Look for The green and white wire that goes down under your left foot peg into a sensor. Take that green and white wire in ground it to the chassis and you should be fine
@@jakemir I tried with mine that didn’t work
couldn’t u just get a new cdi box???
A CDI box is very expensive because you can only use an OEM box. Connecting a ground wire is much easier and less expensive
This is literally the only video that I could find that related exactly to my issue and yet went right when the video starts getting informative you cut out and start showing pictures come on dude
Sorry, it is a simple fix but it is the reverse ground wire. Another way to repair this issue is on the left side of the motor underneath the foot peg there is a green and white wire going to the reverse sensor. If you remove this wire and ground it to the chassis or the motor it will solve the issue.
@@jakemir do you ground both wires?
Ground the wire at the reverse sensor under the left foot p g or cut the wire near the CDI box and ground it there. The issue is the reverse s bait fails to ground out so the CDI thinks it is in reverse.
