Fact or Fiction?

Hello Folks.
Was there any truth in the rumours of the day.
That the sohc 750k's were detuned after the K2.
Then the original power restored on the F1?
Just curious.
Sean.

Trigger:
All the engines were basically the same ( apart from the evolution of the engines) .  F1 and all F2 had higher compression domed pistons and the F2 had the bigger valves. So, were do you get this bull shite ?  ;D
Carbs are basically all the same, apart from the F2 and late K's had PD carbs
 

K2-K6:
Some info here to sort out what happened and why.

As Trigger says,  all the pre F series engines are effectively the same design with no claims to a different horsepower rating for each of them, 67 BHP across the board is quoted.
Emissions and smooth running seem to have brought many minor adjustments.

Trigger:
Most of the little changes like the cams and the inner baffles were only on yank units. The UK K2, that ran from 1972 to 1975 were identical in the engine department internals  ;)

Arch stanton:
As I said. It was the word at the time.
It was also  said of the Z900 & the S/KH250's
I just thought I'd raise the subject.
