I know nothing about cranks, however I currently have my sump off and couldn't help but notice that my crank wasn't completely stock-looking.
Is this considered to be knife-edged or is it just a bit of grinding to balance it up? Not all counter-weights are done evenly - some have very little grinding, some have quite a bit.
is it correct to assume that this sort of mod would have an impact on response and driveability similar to that of a lightened flywheel?
I'm also assuming the machine shop needs to take care to ensure that the end product is balanced yes?

My KE'd crank is for sale :D
what kind of $$$$$$? PM me maybe?

Mate it was machined by a fitter machinist who competed in Targa Tasie 3 times and finished. It was for but never got into his lancer 2000
HE WAS 73 YEARS YOUNG THEN But unfortunately fell off the roof of s new shed he was building
If you are serious I would have it checked to ensure that it is A OK & find out the postage to NZ

well I have had an estimate of $240 +gst to fix my crank so am looking at other options too

By "fix it " hopefully that does not involve grinding it undersize as that will require re nitradeing .IMHO you will be better off with a crank that tests straight and only requires linishing of the bearing surfaces

have not yet taken the crank for a proper assessment but it will probably need a 30-40thou grind
