bluebanshee98 Posted May 6, 2014 Report Share Posted May 6, 2014 I had a 4 mil dune port with shearers and k&n pods. Jetting was 340 mains 27.5 pilots and 1.5 airscrew. Your prob need a 30 pilot and try 330 main and see what the plugs are like. Better to start rich and work your way down? Call Kev he ported your cylinders he SHOULD know...

MLack Posted June 27, 2014 Author Report Share Posted June 27, 2014 Figured i would update this for someone searching in the future. After a few plug chops and running this through the woods i ended up at a 350 main, middle clip on the needle. 27.5 pilot and 1.5 on the screws. Shes a monster!
