exactly as the title states, i wanna know how to change my main jet

 

get the carb positioned upside down, watch out there is fuel in there and will run out. you can do it without removing the throttle but it's a pain. pull off the bowl on the bottom. the screws are a pain to get out. most people go to a hardware store and get allen head screws for them. the best thing i've found to get out the stock screws is a drill that has torque settings on it with #2 screwdriver bit in it. after the float bowl is off, your main jet is the one inside the brass tube. it's the largest one in there, if it is stock jetted for sea level then it should say 150 on it or something close to that.

hope this helps
