The forks from the factory were out of lateral balance by almost THREE POUNDS.

Way too much for my taste. Time to go to work.

First thing to do was to find a place to put the weight. This hadn't been a problem on my old Classic with the open forks, but now we have to go poking about in the innards to find a place.
 
Four small screws let you remove the battery box, and one set screw holds the back cover in place. It slides out once you back out the retaining set screw.

I had a lead brick lying about, a souvenir from my glow-in-the-dark days of growing up around the nuclear industry. I cut a chunk off one end, and started carving it into something that would fit.

Built in two pieces
A main block (intentionally light) and a trim block
 

Assembled weight before trimming
Trimming for final balance
 
A few trial fits to check for progress and a few passes through the mill brought the final weight to what it needed to be: 2 lb. 11 oz.

Bolted in place - It fits!
