New member here,
I have searched here and other places and have not found an answer to my problem. As the title says I have a 2014 420 Rancher that recently started having an issue were the revs before the clutch engages.
I have checked the oil level (per the service manual) and replace the Valvoline ATV 10w40(less than 5 hours) with 10W30 GN4 for good measure. I have used the "pin" method to pull a DTC. I shows a 8-1 which is a TPS error. This makes some sense, as if the computer doesn't read throttle position correctly, it could have this symptom. I have checked the source voltage, and tested the TPS off the quad with a Fluke and a power supply at 5v. It is smooth and does not seem to be a bad sensor. I am confused by the DTC, because the PS light blinks the code, not the check engine light. However, there are no PS codes of that value. This condition appeared after a couple days of driving in the cold (~32°) and driving though some water/bogs.
A couple questions. First has anyone seen this issue, and do you have any suggestions? I have followed the troubleshoot right up to the point of replacing the ECU, which I don't seem to have one on the shelf :)
Second, anyone used a OBDII reader with an a 4pin adapter to pull codes? If so, what system do you use?
Beyond the rev issue, the quad runs and starts perfectly and when it decides, the clutch grabs tight (no slipping)

I rebuilt the top end, rebuilt the carb, and replaced the reed. Starts, runs and idles but has no power. Cant barely move itself with no one on it. Air filter ok. Sounds like its bogged down with throttle open. Compression test showed 140 psi. Plug looks good. Gaskets look good. Im lost. Any suggestions??????

I'm new here, so I would like to say "Hello" to everyone and hopefully, someone will be able to point me in the right direction to troubleshoot an issue. Last night I was riding and all of a sudden ATV lost power and shut down. I was able to get it shifted back down to neutral and tried to restart it. Neutral light on, engine cranks, but it will not start. I haven't really looked at it yet to attempt dieagnoses, since it was getting dark and needed to get it pulled back to garage. Any Idea's of where I should start troubleshooting?? Thanks for any and all help!
