Okay I have been messing with this bike now on and off for about 4 months, needed a new wiring harness someone put wrong one on, now i can't get it to start or run is a better example. everything is fine now with wiring , i try crankin(yes its getting gas, yes lines are hooked up correctly) it won't start but if i spray carb cleaner if will fire over once then stop ..suggestions?

 

Getting fuel from the fuel pump to the carb? Carb clean,new carb kit? If you're getting fuel,the carb is ok,then could possibly be an ecm problem. One of the first ones Polaris used. It controls several different functions and if any of the internal circuit breakers fail,could be the problem you're having.
