I used to run an 18 ZVH with big valve head, kent cam, 4 branch manifold and full stainless exhaust, polished/ported and skimmed head on R6 bike carbs. Id say it made around 130ish
You cant rev any higher than a standard CVH as its the valve springs etc in the head that are the weak link. You dont need to rev that high anyway unless your running a full spec race cam with top end power.
I ran the standard dizzy setup although you will benefit slightly from standalone ecu
