IMO id upgrade your reed cage as well, I've got basically the same mods as you and have a 39mm PWK on there right now I've got a 42 pilot jet and a 175 main. With the cold weather and fresh top end its still a little too lean for my liking. Elevation here is around 500m, don't know what it is there and weather wise I don't know either bud id say start with the 42 pilot and like a 165 main. I also have my needle clip on the last notch
