Having a weird issue with my 99 Polaris Xplorer 300. It's of the 2smoke variety.
Runs great. Carb rebuilt and dialed in by someone who knows what they're doing (not me). Plug isn't reading lean.
If I nail it from sitting still, it runs great. If I'm on a trail and on/off the throttle constantly, it's fine.
It seems if I run constant throttle for more than 1/4 mile, it starts acting like it's running very lean or out of fuel. In fact, a while back, one of my friends thought it was funny to turn off the fuel shutoff and it sounds exactly the same. If I stop and let it idle, it will run fine again. Or if I keep going it will start bogging out like it has no gas. And sitting lets it figure itself out and it's fine again.
I don't believe it's a carb issue. If it was a carb issue, seems like it would have lean issues at wide open throttle or flood / require choke at idle. Runs great except on extended sustained speed.
