As it has what looks like a non-standard Amal TT or GP carb who knows what else inside the motor has been tuned :?:
You can either put the bike on a rolling road dyno or give us the top speed and weight of the bike and the rider –there is an App on the internet that will show the BHP from the above information.

That is actually the standard roadgoing Amal sidefloat carb for the early 1950s,
so my comments about iron engines still apply.
It does have a fancy new alloy bellmouth...
(hard to know if that would help or hinder).

Yes you can work backwards from the top speed.
But revving the zinger out of old iron is not entirely recommended - if you want it to last ?
Maybe 75 or even 80 mph, would that be about 20 horses - give or take a few ?
I've never seen it quoted anyplace, certainly not officially.
