Looks pretty good to me except for the price. Should work well on the Busa w/o changing the actual valve stem.

I would not add any weight to the factory rubber stem.
Replace with metal stem.
That's why in the description it saysI would not add any weight to the factory rubber stem.
Replace with metal stem.
My thoughts too
From the website I listed,CBX, I understand your position, however let me add my thoughts. Adding this extension for the sole purpose of checking and filling (then removing) is fine. Adding it and keeping it on there will rip your stock stem out of wheel at time vs speed. Good luck.
Thanks Steven, Rock and Greg.
