So a day ago i painted my bike body parts everything is nice and smooth no flaws , and today i have decided to spray lacquer i went outside in my garden prepared everything and started spraying as i got nice and smooth finish and brought these parts back into the house to dry them , and after 5 minutes i noticed this strange pattern coming on , maybe someone have a clue what caused it or how to prevent from happening .
lacquer i mixed 2:1 as its says on the can .

OK heres the problem your black base color says its a synthetic enamel ( not lacquer) as we call it. your clear coat is a 2 part catalyzed urethane. what happened is the synthetic enamel doesn't like a catalyzed material put over it, unless it its self is catalyzed. i think you could do this? IF you catalyzed the black synthetic enamel. (MAYBE ). you'll need to strip it down and do it over. looks like you had a NICE finish to start with. synthetic enamels are quite sensitive you would be better off getting a urethane black color.
