Since I discovered that the stock Mikuni needles are starving the top end on my 727 today. What Needles and slide springs are all you big bore/stock carbed Rappy's running?

Dyno jet,
are you sure it's the needles and not the needle valves themselves that do not allow enough fuel into the carb to keep up with the demand?

Either one will effect the fuel flow. Thinner needles will flow more fuel or drilling out the needle jets will also flow more fuel. I picked up some Dynojet needles today which should help. If it's still not enough, I'm gonna start drilling the needle jet until I get the desired results.
