So I finally started the atv for the first time today after the rebuild and it's running way too rich. I have replaced the 39/40mm PWK with a smaller 36 PWK and I am trying to get the jetting right. I have already dropped the pilot 2 sizes to a #42 and after warming up and riding it at 0-1/4 throttle it is still rich (smokes a lot and plug comes out wet.)

Is it normal to be so rich at such small pilot size?? I expected to be around 45-50, instead I might have to go to 38! Anyone jetted a 36 PWK on these quad before?

Again, im at stock bore (67mm) with open airbox and fatty pipe.
