put the 85mm 12:1 je piston and a stage 1 hot cam in-stock main jet was a 145 am up to a 167.5 and still running kind of lean-has anyone any idea how far i should jump or do i have to keep getting 1 jet at a time?thanks

 

Well the wife has a 366 12.1 with a stage 1 hot cam..im running a 155 main in it..but im in oklahoma..try just going up on your pilot..before going up on your main...Here is how you can tell if its your main or you pilot...get the motor warm..hurry up and put a new plug in it..run it wide open and kill it..then see what color you plug is..if you kill it at a ideal..it will show if your lean in the pilot..and if you kill it a full go..it will show you if your lean on your main...what color is your plug now? the best thing to do..if you can..is put it on a dyno..and they will tell you what jets to put in it and it will be just right..
