1975 750S --why can't Guzzi do 70 hp now?
not-fishing:
Depending on where you look the Crank horsepower is 70-90 back in 1975.
Why can't Guzzi do it now with all the whiz-bang-computer technology and advances in the last 35 years?
Is it the gasoline is not as good?
and I admit when I had hair I was a blond it this question seems a little dumb

you're comparing the small block heron head to the big block hemi.

If the "where you look" included the Motorcycle Magazines of the times ... they used to lie like big dogs about "horsepower"; I get the impression they would measure it at the rear wheel, extrapolate it to the piston crown, and report THAT as the "horsepower".
On the other hand, no one makes a gasoline-engined car any more like my 1990 Kia/Ford Festiva (Mazda 121) that gets 44 MPG overall, either, so maybe a combination of modern heavier weights and bad gasoline is part of the culprit ....

I think they were using slide rules to compute block hp and rounding up by 15. :BEER:

In the 60s an English moto journalist asked the Montesa importer haow much power their new 250 MXer made .
He asked "How much is Bultaco claiming , our's makes one more" ::)
