Popping on Throttle off
Posted: Wed Feb 11, 2009 12:36 pm
Hi all just got my Z!b back together after head rebuild,Starts and run fine but getting popping on throttle off,have checked headers,carb rubbers all seem fine,carbs cleaned and jets ultrasonic cleaned.have altered pilot screw but does not seem to alter engine tick over speed? always thought popping indicated lean condition or air leak any ideas?.The bike is not on the road so i am only able to check off load,seems only popping out of one exhaust but hard to tell which one, any way of telling?Cheers Paul J...
