recently got my rmx 250 going and could use some jetting help. the bike has a new topend, new air filter, no airbox lid, fmf fatty pipe and a pro-core silencer. fresh 32:1 mix. i haven't done much riding with it yet but haven't fouled a plug yet either. it will die off at idle after a few seconds and transfering from idle to just off idle is a little rough. i have adjusted the air screw out to about 2.5 turns to get it to idle a little better but the idle screw makes no change. so according to the jetting links that means i need to step down to a lean pilot jet correct? the mid-range throttle response is nice and clean. wide open throttle does get a little gurgly sounding. again that means i need a leaner main jet correct? also when riding if i stall it out it sometimes will not refire unless it sits for a few minutes. any help on that or what jets i need to try to help fix the problems. it is a mikuni carb. pilot jet is a 45 and main is a 230. thanks
