Who did your port work? They would be the best person to ask on the jetting for their work.

[Bansh-eman]

With stock carbs, lid off air box, pipes, and porting from 0-1500 feet most guys are running 320 mains, 27.5 pilots, middle clip, 2.5 turns to start with, than fine tune from there.

[AKheathen]

2.5? and are most running freezing temps?

not to pick at you, just seems off....... i'd suggest the 27.5's, 1 turn, and 330 or 340 to start in those conditions, with the setup you also discribed.....needle in middle, or 1 clip rich, too

i tried bumping my pilot to 27.5 and i couldnt get it to run for shit. i'm not ported yet but for my set up stock pilot is best. however for cold temps and port 310 seems low i'd go 340 and see how that goes

If your not ported with those pipes then the 27.5 will be to rich for your bike. Stay with the 25.

 

As for the other guy. I would go with AK on the jetting.

An aggressive dune drag can run all the way up to 420s on the main,you need to find out the durations of your porting so you know what your dealing with one mans porting is diffrent from anothers
