07NMbanshee

Ok everyone i have a 00 banshee with a fresh rebuild that needs to be jetted badly, try reading the plugs help from other people and take their advise but it just gets worse. Heres what i got: -.80 bored with vitos super stock pistons -custom ported cylinders -4mm stroker crank -vitos hemi head 2 w 17cc domes -vitos aluminum intake manifolds with bullseye fins - NO boost bottle or pipe -vforce 3's -TORS eliminator kit -no lid intake w k&N -fmf gold sst -timing plate @ +4 5000' elevation when i got it back from my engine builder, drove it for 4 tanks during break-in process using motul 800 at 32:1 as soon as i got on it, my plug backed out so i figured it was either lean or lose. tightend it back up and went for another run and it made a hole in the piston. Got that mess taken care of and redid it myself and found it has 300 mains and the vitos needle on the middle clip. I went up to 330 it ran better but not right. got it on 360 and it just dosnt hit right. Please help im not too great wit this
