The first thing I would do is get a few tanks of fuel through it to break it in. Then gradually start leaning the needles. I was surprised just how rich the low end was set on my .82 from the factory.
No kidding!
The Saito's seem to have a very WIDE tolerance for improper tuning.
They'll keep idling with the LS needle extremely rich.... as it comes from the factory.
After a gallon of fuel I started turning the LS needle in and I was amazed at how far I turned it ( 2.5+ turns IN ) before I hit the idle sweet spot.
