What is the standard warm up most of you guys use? I let mine idle (blipping the throttle every few seconds) for about a minute and a half, then ride it easy for another minute. It seems to take my 03 200 forever to run clean. It smokes quiet a bit for the first few minutes. ( I understand thats part of a two stroke) Perhaps it's a bit rich............... I had thought of opening up the airbox a bit, since it seems to be a popular thing to do around this board. That may lean it out a bit, and make it run a little better, but I'm a bit hesitant. I'd rather error toward the side of caution and run it rich. How much will the air box mod lean it up? Any carb adjustments needed? As always, thanks for all the help.
