I made mine serviceable. I have a small mill, so did a bit of work to allow me to change oil, bleed it, and recharge it. You can see that my first attempt with the end mill didn't go too well, but it came out OK. (I am not a machinist, but someone who can get it done. There is a big difference.)
That being said, after i had it apart, cleaned up, and re-installed, I rode it. It was fine, and with a slightly heavier oil (same shimming), the damping was "firmer." Yamaha builds/buys to a price point, and I'm sort of a suspension snob, so after seeing what was inside, i decided to go Penske. It didn't hurt that i had a Penske on my 690 Duke - it really made a difference there.
This was before I knew about Terry. I have used Terry for my dirt bikes, and i was super-impressed, and he's "next door" in Idaho.
The Penske is a really nice piece - I'll probably keep it if i ever sell the S-10 (which is highly unlikely) and install it on a new bike.
