I have a ZSTAR 110 CC MODEL... when you start it up SOMETIMES it will back fire and blow white smoke out of the carb,,,, pre-igntion... It trys to fire to soon... but then it is ok after that one time.. you wait for a long time and maybe it will do it again... I change the carb... I raise the rod in the carb (like it says in the carb setting section here) to try to lower the amount of fuel setting.. could it be the CDI .. or ingition coil??? any help would be good.. P.S. sometimes there is a big bang from the motor trying to fire up.. but it runs great when it starts and runs.???
