Taking a flywheel I got for $10 on ebay to the shop to have it lightened. What's the lingo to tell the guy what to do? Just "Make it lighter? A certain thickness that goes along with the task? There's a place in Marina Del Rey that will do it for $30. Seems worth it.

So the flywheel being lighter is going to be better for the engine because it's turning less weight, correct?

Thanks again.

If anyone needs my old one when it comes off, let me know.
