Default Re: Curious about the engine, :question:

This is a 40mm crank with the ZL rod. Look how close the pin is to the counterweight. Its what is in my FH engine. They seem to be dwindling in supply. These are $20 shipped off ebay. Mine is a fairly smooth engine. There are some cranks with the ZL rod that don't have the two balance? holes, I believe those are older/inferior.
