coooool, no stop slacking and get them mods on ur ATV.. times a wasting

 

i'm assuming you got the pwk 39?
on a stock motor with a trail pipe it should fit a 165 to 168 main,for
winter time you can go til 170 main but a plug check is the right anwser
to what it will take.it might take a 38 pilot or richer also.as been told
earlier,get more knowlegde on the carb before any change.
