My YZ250f was popping a lot when i let of the gas and i know that is a sign of the bike running too lean. Well i bumped up my slow jet from a 42 to a 45. and the popping seems to have left, but sometimes still a slight pop, but what really bugs me is that I added the Boyesen Quickshot and when i snap the throttle it bogs. Could this be a sign that my bike is still a little lean and i need to up the slow jet again? Im thinking the slow jet isnt supplying enough fuel when I snap the throttle that is causing the bog. Any suggestions are appreciated. Thanks.
