REFLECTOR: Piston

[nmflyer1 at aol.com]

Have a good engine speed shop add some "heavy metal" to the wrist pin to get the weight right. They can get it exact. Don't use a discount engine shop, use a custom speed shop. My engine is balanced to less than 1/2 gram.

I'm replacing a piston.  The new one is 35 grams lighter than the old
one.  I need to have the weight the same as the opposing piston.  I
could machine the opposing one or replace it with a lighter one, but I'd
prefer if I didn't have to.  Can I add weight inside the wrist pin of
the lighter one?
