Just an update on the 2 stroke quad. Just a reminder, Polaris Xployer 400, with piston size one over. I’m struggling with jetting. I’ve gone back to factory settings. Idles great, but bogs when coming onto the main. If you feather the throttle you can work through the big and she’ll run well... it’s difficult to access the carb with the air filter boot in place. If I pull the air filter, no bog, revs out with no issue, no bog, no hesitation. Put the air filter back on, and she struggles. I’m thinking it’s too lean with the air filter in place.. I’ve adjusted the clip position and have tried turning the air screw in and out with out much success.
One other thought... this machine in oil injected. When I put her back together, all I had was bel ray premix, not 2 stroke oil for oil injection systems. I’m wondering if that could be the underlying cause...
Help me out guys, I’m stumped
