I'd personally imagine that a change to 32:1 would need very little change in jetting. Especially if moving from 40:1. Maybe some slight adjustment on the main and pilot. I can't see it being anymore of a variable than temp &/ humidity.
Best bet is to mix a tank and run the bike. It'll tell the story. I have a KX needle here (NAFW I think) and its way too rich to work in my gasser, even in top clip). Remember the KX will be running a lighter flywheel, as well as all the other variables. It was also designed as an MX bike where the Gasser isn't.
