runing on

Frank Collette /

Hello, i have a 50pkxlz that is running on. dead cold it doesnt, but after afew seconds it takes time for the reved engine to return to an idle. someone says it is sucking air due to high vacuum pressure. any methodology to trace the source of where the air is coming from????

Re: runing on

Spray carb cleaner around suspected spots when the bike is running on the stand at a constant speed. If the engine bogs, wherever you are spraying is where the air is coming in.
