finman Posted March 14, 2006 Author Report Share Posted March 14, 2006 What kind of porting? Always recommend to ask who ported what jets first! We have had them from 320 -440 on stock carbs. Depends on the port work. I would GUESS around 360-380 range should be safe! Always start rich and come down. 486594[/snapback] Jeff, I believe the port job was one for all around. It was done on cnc machine. Has the side holes drilled on the intake side. I believe main jet is 340. Quote Link to comment Share on other sites More sharing options...
badassbanshee479 Posted March 14, 2006 Report Share Posted March 14, 2006 take it up a couple on the main jet, do a plug chop and jet down form there. were do you have the needles set? are they stock needles?? what piloit are you running? all these things lead to the running condision of your motor. try a 360 main and see what the plugs look like, there is an article in the jetting page on this forum that has some good tips, you should check it out.
