Greg, thanks for the commentary.
Grinder (and others), it seems the real fast (and economical) engines are 11.5 cranks (cap, rb m3, orcan, old RB and max, and others) yet more and more are coming out 11.9. Why do you think this is? What are the arguments/reasons?
I also want to know the reason(s) why novarossi is switching from 11.5 to 11.9 crankshaft.
