the fz1 carbs run a one liter engine 11,000 rpm producing 130 hp. I have an fz1 & love it.

They are very good carbs. Just bolt them on and run the engine a little with a wideband oxygen meter. That will give you a reasonable starting point for jetting. Dyno runs are important to get it right.

The jets are commonly available. I advise against drilling them as the bit does not leave a clean bore.
