I just bought a 03 z400, and when i was riding i noticed that to me it seems like it is running a little lean, because when i let off the gas when coasting or coming down a hill in any gear it pops a few times like its sucking to much air or something. Maybe i'm wrong and its too rich but any help would be great! There is no airbox lid but i rigged one out of cardboard to see if it helped but no luck. The guy i bought it from said it had been jetted for the pro circuit t-4 exhaust. Thanks in advance!
