I run a very similar set up with kein 28's,boss intakes,+no reed spacers.My optium jetting at sea level @70deg is a 48 pilot,165 main,clip on the leanist setting,1+ 3/4out on the air screws.Thats with k+n clamp ons.Do a W.O.T. plug chop.Dial in the mains first+then work your way down through the rest of the circuits.Only change or adj one thing at a time+test.This will take some time+patience,but it will be well worth it.
