Hello everyone,

I have a 2016 cforce 500 with around 230 miles on it. Took it out riding and now it will not stay running on idle. If I give it some throttle it will stay running but let off and it dies.

We didnt go through any water and the trails weren't dusty.

So far I have looked at the airfilter, added new gas, check for strong spark, made sure the throttle wasn't stuck, and even kicked it a few times. Ant help would he great. Thank you

Try the easy stuff first. In this case, I would start by cleaning the mass air flow/air temp sensor.

An easy test is fuel pressure, before that I would tap the fuel module in the tank. Stuck sticking fuel pressure regulator that won't allow fuel pressure to build...... will cause your exact symptom. I've seen this first hand with 800's, not with the 500's, I'm assuming same fuel system.

I would for sure look into the simple stuff first.  Make sure you are getting air into the engine, then look for fuel pressure and the TPS.
