You didn't say if the v boost was left normal or you installed the manifold
pieces.It would be easier to diagnose if you could isolate the carbs.

>Actual situation:
>
>A).-Stage Seven Kit, 175 mains, air restrictors installed, soft springs,
>drilled slides, needles in fourth position from top as Dynojet recommends.
>
>B).-Two Bros Racing oval slip-ons (absolutely free 2 1/2", see through
>cans).
>
>C).-K&N individual filters.
>
>RESULT: Gutless engine from start to end.
>
>Plug reading: Pearl white ceramic and white/grey rest (checked after 50
>miles along country roads and later on heavy traffic for 1/2 an hour till I
>got home ).
>My belief: bike running too lean.
>
>Second test: change fourth to sixth position on the needles ( max fuel
>intake).
>Rest absolutely the same. (a bit drastic, but I had to try)....
>
>RESULT: Bad idle, cannot use choke since engine stalls. once on the road
>with traffic, bike has a mid range flat between 3K to 5K, then clears and
>wham! the bike goes once more like a rocket.
>
>Plug reading: Too tired to check, but bet they are black due to too rich
>mid range condition.
>
>So, what Am I left with? Just the fifth position, but who can understand
>such a big difference in behaviour between two notches on the needles?
>Surely that cannot be right.

>Any clues?
