No, in fact I don't even read the rennlist anymore since I found the pelican forums.

That fact aside, I can think of a lot better places to spend my money than whittling down the crank.

I can see the sense in it for some motor being set up to regularily spin over at 8K RPMs but my motor will rarely ever see even 7K.

If I wanted to lighten up the rotating mass I could easily start with the clutch. That damn 930 pressure plate weighs over 20 lbs. I have concidered going to an aftermarket aluminum unit when the current clutch wears out.
