Getting some new goodies!

[honda4life]

Dellorto 19mm stage 6 carb, jets, new throttle cable and cf reeds for the Zuma.
Any tips on installing these? Pretty straight forward? I know the carb is supposed to be "easier" to swap jets out. Not sure about that.
Any suggestions would be great to avoid issues I may have.
Stock jet was 73? So I'm guessing I should stay around that? Or maybe go with a 80 and work my way back down?
Even though the carb is larger (getting ready for the bbk next spring) I don't think there is much more airflow because of the stock airbox and exhaust.
Right?

Start rich and work down, less risk to the engine. Did you get dell needles too?

[honda4life]

No just the W7 needle that came with it
It has four slots and it's on the second one from the top

W7 is a highly recommended starting needle. If you find that you are midthrottle rich on one slot, then move the needle one leaner and gets too lean, you might need a richer (longer taper) needle. But other folks here can help get you dialed perfect better than i can

I would start larger than an 80 with the Dell. Prob in the 90s and work down if needed. I've never bought a 19mm, but my 21mm Dells came with 92 main jets. I assume the 19mm wouldn't be far off. Most of mine use 95-105 mains with a stock airbox with a mod to the inlet.
