This seems to have been covered constantly but mostly in relation to the nc30.
So if someone in the know wouldn't mind repeating themselves....

OK so its an NC35 with 3/4 system.

its been tuned twice, first time no bottom end
2nd time (now) using some unused jets for a CBR400(not sure what size) great bottom end leaning out in higher up under gentle throttle.

i've got a new OEM filter just wanted to get an idea for what settings i should be playing with. got a mechanic who's helpful and won't rape me for dyno time.

so what jets do i source for the dyno run>?
Its a road bike but i do track days on it.
also rubber membrane that sits under carbs, keep in or not>?

Hey mate long time no hear!

I'd start with 112 main jets all round, and a pilot screw setting of 2 turns out. Can't go much wrong with that.

You can get the keihin jets from 'show and go' in Oz, just google them.

I'd leave the airbox/flap standard, although modifying these isn't as detrimental to nc35 as it is nc30's.
