Hi D, For many years I used stock A14 cranks, but I would only use the 9000-9800 rpm sparingly. On the dyno, operators can see a harmonic at around 7800 rpm due to crankshaft flex.
Now with billet cranks, I am routinely using 9600-10,000 rpm.
I agree that there are probably only 1-2 that want to purchase. But, I had to ask! Peter
