on this model you have to take fuel tank almost off to change plug. its a two stroke
and idles fine even when reving it up at high rpms if it was fuel than i would think it would be smoking or missing when idling. could the fuel filter be what causes it at high speeds. when im going about 50 mph it feels like there is still plenty of throtle left then i push it in and it stalls much like a governer does on a vehical. the two stroke oil is injected internaly. it seems two be working fine
dont have one. heres something else i thought of the gas adjustment in the carb looked liked it was screwed in two tight and left an indention in the seat so when you turn it one way or another now thers no change in the idle. so i adjusted it on the electronic throttle.
but even still before i adjusted anything it still ran out the same polaris i have always heard are tricky. woulded have a qestion on my yamaha or hoda easily rebuilt them this one is different
