stock 250 a/s jetting

[Luke22]

Hey guys. I just bought a 38mm a/s carb for my 88 250 r and she's all stock. Anyways I was wondering if anyone could give me a ballpark on the jetting I'm gonna run with the air box lid off. Thanks for the help and I tried doing my searching.

stock is 45 pilot and a 158 to 152 main start there and see what you got it shouldnt make that much of a difference with the carb on the jetting and start with the needle in the middle clip and the air screw at 1 1/2 tuns out from lightly seated go from see how she runs
