I started with fuel screws at 1 turn out but after a few test hits the plugs had a little tiny whiter look to them so I went to 1 1/2.
I'll go back to stock at 1 1/8 with needles at top. 42.5 pilots sounds a little lite dont I need more fuel because of the load on engine at the line? Thank you
Appreciate the help. I hated losing to a xc700.
With your needles all the way up and a higher engagement your already starting the powerband of motor on the needles. Stock 42.5 pilots will do just fine. You dont need to be so fat on pilots for drag racing. Stock fuel screw settings and 135 mains worked well for me.
