I have a 98 Polaris 300 ex RPM is good at idle, when throttled near 1/2 engine bogs down, I think the rev limiter is causing this. Would a rev limiter bypass help this. Any assistance welcome

Welcome! You can always pop the front panel and disconnect the black wire on the module and see if it helps. But could be the carb needs to be cleaned also,could have a jet stopped up,trash under the float needle slowing fuel flow,etc. OPT

The carb has been rebuilt, new plug and filters. When I disconnect black wire engine revs to full trottle but will not go into 4x4 mode or turn off engine with key. Problem is definatly electric, and the rev limiter,

do you know how to bypass this

You must have pulled the cdi kill wire if it won't kill with the key switch! Item #28 is the reverse limiter. Dirt Cheap Yamaha, Honda, Arctic Cat & Polaris OEM Parts & Accessories – Cycle Parts Warehouse
