Jetting 2012 Superjet

[N3vrSat1sfied]

I've never messed with 38's before. I removed the choke plates for a primer and she got lean. I cant safely turn the highs out anymore (I drilled the tamper proofs off when I did the choke). I need to go up a main jet size. I figured some screw adjustment would be needed but didn't expect a jet change, Just curious if anybody else has done it and what are your jetting specs?

rest of engine is all stock, including flame arrestors.

Bumping this up, i could use good oem dual 38 settings for a stock engine, stock pipe. From the factory they come a bit rich right?
